OEM vs Aftermarket Shocks: Which Are Better for Your DeVille?
When it comes time to replace the shocks on your 2024 Cadillac DeVille, you have an important decision to make. Should you stick with original equipment manufacturer (OEM) shocks from Cadillac, or go with an aftermarket option from a third-party brand? There are pros and cons to both that are worth considering.
OEM Shocks
OEM shocks are designed specifically for your DeVille by Cadillac engineers to meet the factory specifications for ride quality, handling, and durability. Here are some of the benefits of sticking with OEM shocks:
- Guaranteed fit – Since they are made for your exact make and model, you know OEM shocks will bolt up perfectly without any modifications needed.
- Maintain original ride – OEM shocks are tuned to provide the same ride feel that your DeVille had when it was new.
- Manufacturer tested – OEM parts undergo rigorous testing to ensure they meet Cadillac’s high standards.
- Designed for specific vehicle – OEM shocks are engineered to compensate for the weight and suspension geometry unique to the DeVille.
- Warranty – OEM shocks usually come with a warranty from Cadillac against defects for 12 months or 12,000 miles.
However, there are some downsides to OEM shocks to be aware of:
- More expensive – Since they are made exclusively for Cadillac, OEM shocks typically cost more than aftermarket options.
- Less customization – You get the factory shock valving whether it suits your needs or not.
Aftermarket Shocks
Aftermarket shock brands like Bilstein, KYB, and Monroe offer shock absorbers engineered as direct replacements for OEM shocks. Here are some potential advantages of aftermarket shocks for your DeVille:
- Lower cost – Aftermarket shocks are usually cheaper than OEM for the same level of quality.
- Customization – You can choose shock valving optimized for different needs like sporty handling or a plush luxury ride.

Potential downsides of aftermarket shocks include:
- No vehicle-specific design – Aftermarket shocks are designed to fit a range of vehicles, not just your DeVille.
- Durability variance – Quality and longevity can vary more between aftermarket brands.
- No factory warranty – You usually get a 1-2 year warranty from the brand instead of Cadillac’s backing.
Picking the Best Shocks for Your Needs
So which is the better option – OEM or aftermarket shocks? There’s no definitive answer, as a lot depends on your budget and priorities. Here are a few tips for choosing shocks for your 2024 DeVille:
- If maintaining a factory ride is critical, OEM is the way to go.
- If you want to fine-tune the handling and ride or get increased durability, consider aftermarket.
- Research brands thoroughly and read reviews to find reliable aftermarket shocks.
- For a blend of OEM design and aftermarket quality, look at brands that partner with Cadillac like Monroe Reflex.
- Consider your mileage and length of ownership. OEM shocks may be the better value if you don’t put many miles on.
It’s a good idea to replace all 4 shocks as a set to keep the suspension balanced. Plan to have a professional shop do the installation to avoid any issues with fit or alignment. With proper maintenance and parts, your 2024 DeVille’s suspension should provide the responsive yet comfortable ride Cadillac intended for many years.
Top Considerations When Upgrading Your Cadillac’s Suspension
If you’re looking to enhance your Cadillac’s handling and ride quality, upgrading the suspension is a great mod. But before you dive in, it’s important to think through what you want to achieve, your budget, and how intense you plan to get with modifications. Here are some key factors to consider when planning suspension upgrades on your Cadillac:
Set Your Goals
First, define what type of improvements you want from suspension modifications. Possibilities include:
- Lowering the stance for style
- Reducing body roll in corners
- Improving ride comfort and compliance
- Increasing cornering grip and control
- Enhancing high-speed stability
Be realistic about which goals are achievable and compatible. For example, you may have to balance ride quality and handling based on how aggressively you’ll drive.
Consider Your Budget
Suspension upgrades can range from a few hundred dollars for basic springs and shocks to $5,000+ for an adjustable coilover kit with camber plates. Set a reasonable budget that aligns with your goals. Focus first on the most bang-for-buck upgrades like shocks and anti-roll bars, then consider pricier parts like control arms or coilovers down the road.
Research the Options
Major suspension components to research include:
- Shocks – Adjustable shocks provide tunable damping and ride height.
- Springs – Lowering springs paired with quality shocks enhance handling.
- Coilovers – All-in-one units with adjustable shocks and springs.
- Anti-roll bars – Thicker bars reduce body lean for flatter cornering.
- Control arms – Adjustable arms correct geometry and allow alignment tweaks.
- Bushings – Polyurethane bushings tighten steering response.
For each part, read Cadillac forum discussions and reviews to learn about brands, fitment, ride changes, and optimal configurations.
Factor In Usage
How you drive your Cadillac should guide your upgrade path. Lowering your daily driver too much can compromise ride quality and functionality. But going with an extreme setup on a dedicated track car is likely fine. Gauge whether you want a moderate change to enjoy on the street or more aggressive parts for the occasional autocross or track day.
Work With a Trusted Shop
Unless you’re an experienced mechanic, have a reputable shop install suspension upgrades. Cadillac-specific shops are ideal. A good shop will:
- Ensure parts fit properly
- Adjust components like control arms to factory specs
- Perform a full alignment to dial in new settings
- Test drive the car and make tweaks to get the right balance
The right shop can make recommendations and perform the work correctly so you get the most out of upgraded components.
Change Components Methodically
Start with easier bolt-on parts like shocks, springs, and anti-roll bars. Once you’ve tuned those, consider more advanced parts if needed. Changing too much at once makes dialing in the right setup tricky.
Upgrading your Cadillac’s suspension takes research and thoughtful parts selection. But once upgraded properly, you’ll enjoy much sharper handling and cornering ability along with a comfortable ride. Take time to define your goals and budget to pick the ideal upgrades that align with how you drive.
Do You Really Need New Shocks or Just Struts?
When your Cadillac starts showing symptoms like bouncing, nose-diving, or an uneven ride, it’s tempting to think you need all new shocks. But in many cases, replacing just the struts can restore ride quality at a lower cost. Here’s how to determine whether new shocks or struts will fix your Caddy’s suspension issues.
Understanding Shocks vs. Struts
Shocks and struts perform similar damping functions to control bouncing and settle the suspension. But there are some key differences:
- Shocks are separate from the coil spring and mount in the rear suspension of most Cadillacs.
- Struts combine the coil spring and damping unit into a single assembly for the front suspension.
- Struts also provide structural support for alignment, steering, and handling.
So while shocks mainly control bounce, struts perform that job plus support the front suspension geometry.
When to Replace Shocks
Here are signs your Cadillac’s rear shocks need replacement:
- Bouncing after hitting bumps or dips
- Continued bouncing more than 1-2 times after a bump
- Rear end sways side to side on turns or braking
- Excessive rear suspension noises over bumps
- Rear tire cupping or uneven wear
If you notice these symptoms, new rear shocks can restore control and stability. You can replace shocks individually if only one side is bad.
When Struts Need Replacing
Symptoms indicating worn front struts include:
- Nose-diving under braking
- Bouncing after bumps, especially uneven side to side
- Poor steering precision and wandering
- Knocking noises from front suspension
- Uneven front tire wear
Replacing struts comes with an added cost since the labor involves disassembling the suspension. But new struts renew dampening and restore proper wheel alignment.
Inspecting Shocks and Struts
A visual inspection and bounce test can reveal if shocks or struts are worn out:
- Check for oil leaks indicating blown seals
- Inspect for dents or damage to the body
- Push down on each corner and release – worn units will bounce more than twice
If you’re unsure, have a shop put your Cadillac on a lift and check the condition of the shocks and struts.
Prioritizing Replacement
Since struts are tied to wheel alignment, it’s best to replace them in pairs. Plan to get an alignment after new struts are installed.
For shocks, start with the worst side first if you’re spacing out the work. Driving with one new shock can exacerbate suspension imbalance.
Labor costs make struts pricier to replace than shocks. But worn struts undermine the whole front suspension system, so they should take priority if both need replacing.
Using Quality Parts
Don’t cheap out on replacement shocks or struts – the wrong parts can make ride and handling issues worse. Work with your Cadillac repair shop to select quality aftermarket or OE parts that match your car’s year and model.
By understanding the difference between shocks and struts, inspecting for typical symptoms, and using reputable components, you can target just the replacement parts needed to restore your Caddy’s suspension performance.
Rear vs Front Shock Absorbers: Key Differences Explained
Shock absorbers are a critical part of your Cadillac’s suspension system. But the rear and front shocks aren’t identical – they have distinct designs and roles. Understanding the key differences will help you make informed repair and upgrade decisions.
Rear Shock Function
The rear shock absorbers are vertically mounted on most Cadillacs. Their job is to:
- Dampen bounce and oscillation from road impacts
- Help keep the rear tires in contact with the road
- Control rear suspension movement and limit hop
- Influence vehicle pitch during acceleration and braking
Good rear shocks stabilize the car over bumps, improve handling precision, and prevent uneven tire wear. That’s why replacing worn rear shocks restores ride quality and comfort.
Front Strut Function
Front struts perform similar dampening duties to shocks but also provide critical structural support:
- Control bounce just like shock absorbers
- Incorporate the front coil springs
- Hold alignment settings like camber and toe
- Influence steering feel and responsiveness
- Support front suspension components
Worn front struts allow alignment and handling to deteriorate. Replacing struts restores stability, steering precision, and correct geometry.
Design Variances
Here are some key design differences between rear shocks and front struts:
- Shocks use a compression tube with fluid and valves attached to the suspension by the bottom mount and shaft eyelet up top.
- Struts integrate a shock absorber compression tube inside the coil spring assembly bolted at the top and bottom suspension points.
- Shocks move independently and use swing arms to control vertical wheel travel.
- Struts connect more solidly to steering knuckles allowing them to share suspension loads.
Differences in Wear
The tighter integration of struts means they tend to wear out sooner than basic shocks. Here are some patterns of wear:
- Struts usually need replacement between 50-70k miles
- Shocks can often last up to 100k miles before needing replacement
- Bad roads, loads, and driving style impact wear life
- Oil leaks indicate end of life for both
- Bent struts require immediate replacement
Both shocks and struts wear over time and use. But struts are more complex and safety-critical, so they require diligent inspection and timely replacement.
Replacement Considerations
Here are some factors to keep in mind when servicing rear shocks vs. front struts:
- Replace struts in pairs to maintain even suspension geometry
- Staggered shock replacement is ok provided sides are balanced
- Strut replacement requires an alignment to reset positioning
- Shocks are cheaper and easier to swap than complete strut assemblies
- Use high quality replacement parts to avoid premature failure
Understanding the unique roles and service needs of shocks vs struts allows you to make informed repair decisions and keep your Cadillac’s suspension performing its best.
Why Proper Dampening Matters for a Smooth Cadillac Ride
A hallmark of Cadillac models over the years, from vintage to modern, has been delivering a smooth, comfortable ride. Much of that signature Caddy ride quality comes down to proper dampening from the shocks and struts. When they wear out, the ride suffers. Understanding how dampening works illuminates why maintaining the shocks and struts is critical on your Cadillac.
What Dampening Does
The job of dampeners like shocks and struts boils down to controlling the motion of the springs and weight of the vehicle. Here’s how they accomplish this:
- Constrict fluid flow through small openings and shim stacks to control compression and rebound
- Absorb impact forces when wheels hit bumps to isolate the chassis from jolts
- Restrict spring and suspension oscillation after impacts
- Improve traction by keeping tires planted over uneven surfaces
Good dampening stops bounce and wavering motions for a composed ride. Deteriorated dampeners allow the springs to vibrate wildly.
Tuned Cadillac Dampening
Cadillac engineers optimize shock and strut valving specifically for each model. Here’s what they aim for:
- Softer, more compliant dampening for a relaxed freeway cruise
- Firmer control when hitting bumps and dips to limit chassis movement
- Reduced float and wallow through turns for sharper handling
- Proper ride height balance and anti-dive under braking
The factory dampening provides responsive handling without compromising luxury ride comfort when new.
What Happens When Dampening Fails
As shocks and struts wear out, their ability to dampen deteriorates. Typical symptoms include:
- Constant bouncing after hitting bumps or dips
- Excessive chassis leaning and shifting during cornering
- Front suspension diving too deep under braking
- Nose bobbing up and down at highway speeds
- Bottoms out easily over large bumps or when loaded
At this point, the shocks and struts can no longer control the suspension properly, leading to an unstable ride.
Restoring a Smooth Ride
Replacing worn shocks and struts renews your Cadillac’s dampening performance. Here’s what you’ll notice with new dampeners installed:
- Bounce and oscillation quickly dissipates after bumps
- Improved high-speed composure and cornering stability
- Steering response feels sharper
- Passengers feel comfortably isolated from impacts
- Ride height and anti-dive geometry get reset to factory specs
Properly functioning dampening is foundational to the Cadillac motoring experience. Don’t delay getting new shocks or struts when handling and ride comfort decline.

How Often Should You Replace the Shocks on Your DeVille?
Keeping your Cadillac DeVille’s shock absorbers in good working order is key to maintaining that signature smooth and stable Caddy ride. But shocks do gradually wear out over time and mileage. Here’s a guide on determining when it’s time to replace your DeVille’s shocks.
Rear Shock Life Expectancy
Cadillac rear shocks typically last:
- 50,000 – 70,000 miles
- 4-6 years
This can vary based on driving conditions and loads. Signs of declining shock performance indicate replacement time.
Front Strut Life Expectancy
Struts generally need replacement more often than shocks due to their more complex design:
- 30,000 – 50,000 miles
- 3-5 years
Again, inspecting worn strut symptoms means a replacement should be scheduled.
Key Factors in Shock Life
Several factors accelerate shock wear:
- Frequent hauling or towing
- Living in an area with poor roads or harsh weather
- Aggressive driving on curvy roads
- Lowered ride height
- Larger wheel and tire combinations
Conversely, smooth highway commuting extends the shock lifespan. But wear will eventually occur.
Symptoms that Shocks are Worn Out
Replace shocks immediately if you notice:
- Excess bouncing after hitting bumps
