What Suspension Parts Can You Buy Besides Shocks and Struts?
Most suspension projects begin with a familiar problem. The vehicle bounces after bumps, leans through turns, squats under a load, or wanders across the highway. Since shocks and struts affect ride control, they’re usually the first parts people consider.
However, shocks and struts are only part of the suspension system. Depending on the symptom, you may also need springs, sway bars, end links, steering stabilizers, mounts, or other supporting components.
Customers often ask questions such as:
- Do I need sway bars when replacing my shocks and struts?
- Will these lowering springs fit my exact vehicle?
- Can I buy a Bilstein 5100 already assembled with a coil spring?
- Do I need different suspension parts after lifting my truck?
- Are SumoSprings sold individually or as a complete axle kit?
The answer depends on the vehicle, its existing suspension, and the problem you’re trying to correct. Before ordering, it’s important to understand what each part does. You should also confirm availability and fitment for your exact application.
Start With Shocks, Struts, and Complete Strut Assemblies
Shocks and struts control the movement of the vehicle’s springs. They slow down compression and rebound after bumps, dips, turns, and changes in road surface.
Springs support the vehicle’s weight and establish its ride height. Shocks and struts manage how quickly those springs move. A conventional shock generally doesn’t correct sagging ride height or increase the vehicle’s load rating.
ShockWarehouse carries OE-style replacements, heavy-duty shocks, performance dampers, and shocks for lifted applications. Available brands include Bilstein, KYB, Monroe, Rancho, Gabriel, KONI, FOX, Old Man Emu, and ICON.
Bare Struts vs. Complete Strut Assemblies
One of the most important decisions is whether you need a bare strut or a complete strut assembly.
| Option | What It Typically Includes | What to Consider |
|---|---|---|
| Bare strut | The strut or damper only | The original spring, upper mount, bearing, boot, and related parts may need to be reused or replaced separately. |
| Complete strut assembly | Strut, coil spring, upper mount, bearing, boot, and related components | The unit arrives assembled and usually doesn’t require transferring the old spring. |
Installing a bare strut often requires a spring compressor. Compressed coil springs store significant energy, so this job requires the correct equipment and procedures. If you aren’t comfortable working with compressed springs, have a qualified technician complete the installation.
A complete strut assembly costs more than a bare strut. However, it can reduce installation time and replace several worn components at once.
Performance struts, such as many Bilstein B8 5100 applications, are generally sold as bare units. Some 5100 front struts include adjustable spring-seat positions, but they don’t normally arrive as complete loaded assemblies. The original coil spring and other components may still need to be transferred.
Sway Bars, End Links, and Bushings Control Body Roll
Sway bars, also called anti-roll bars or anti-sway bars, address a different type of vehicle movement. Shocks control the speed of suspension movement. A sway bar helps resist excessive side-to-side body roll.
A heavy-duty sway bar may be worth considering when:
- A truck or SUV leans excessively through turns.
- A motorhome feels top-heavy during lane changes.
- Crosswinds make a tall vehicle feel less stable.
- Passing trucks create noticeable side-to-side movement.
- A loaded vehicle needs better roll control.
Hellwig sway bars and suspension components are available for many trucks, SUVs, vans, and motorhome chassis. Coverage is application-specific, so front and rear bars won’t be available for every vehicle.
A sway bar won’t correct an overloaded vehicle, improper weight distribution, or worn steering components. Trailer sway may also require changes to loading, tongue weight, tires, or the hitch system. However, the correct sway bar can help the tow vehicle feel more controlled.
Inspect the End Links and Bushings
Before replacing a sway bar, inspect its end links, frame bushings, brackets, and mounting hardware. Worn or damaged components can create clunks, delayed response, or loose handling.
A good sway bar can’t work correctly if its bushings allow excessive movement. In some cases, replacing worn end links or bushings may restore the response you’re missing.
Choose Springs Based on Ride Height and Load Requirements
The word “springs” covers several different product categories. Some springs lower a performance car, while others lift a truck or provide additional support under a load.
Performance and Lowering Springs
Eibach suspension products include performance springs and suspension options for many cars, trucks, and SUVs. Belltech also offers lowering products for selected applications.
Lowering springs can reduce ride height, decrease the vehicle’s center of gravity, and sharpen handling. However, the rest of the suspension must work with the new height.
Stock-length shocks or struts aren’t automatically appropriate for every lowered application. Excessive lowering can reduce available suspension travel and cause frequent contact with the bump stops. It may also place the damper outside its intended operating range.
The correct setup depends on the amount of lowering, the damper design, and the manufacturer’s recommendations. Springs and dampers should be selected as a matched pair.
Lift Springs and Heavy-Duty Coil Springs
Lift springs increase ride height for specific truck, SUV, and Jeep applications. Heavy-duty coil springs may also help support added accessories or consistent cargo weight.
Any increase in ride height changes the suspension’s operating range. The shocks must have the correct extended and compressed lengths for that lift. Larger lifts may also require geometry corrections or other components that aren’t included with the shocks.
Helper Springs and Load-Support Products
Load-support products address rear suspension squat when a vehicle carries cargo or trailer tongue weight. Available options include SuperSprings, SumoSprings, and Timbren suspension enhancement systems.
These products supplement the factory suspension. Depending on the design, they may engage progressively as the suspension compresses or add support through the vehicle’s existing leaf spring system.
Shocks don’t normally correct rear-end squat because they aren’t the vehicle’s primary weight-supporting components. They may improve motion control, but spring capacity and vehicle loading determine static ride height.
Load-support products can help with:
- Trailer tongue weight
- Slide-in campers
- Work equipment carried in a truck bed
- Consistent cargo or tool weight
- Motorhome weight-related suspension compression
These products don’t increase the vehicle manufacturer’s gross vehicle weight rating, axle rating, tire capacity, or legal payload limit. The vehicle must remain within every published weight rating.
Most helper-spring products are packaged as vehicle-specific kits, but package quantity varies. Check whether the listing covers one axle, one side, or another configuration before ordering.
Steering Stabilizers Address Steering Movement
A steering stabilizer is a horizontally mounted damper or centering device connected to the steering system. It helps control unwanted steering movement rather than supporting the vehicle’s weight.
Depending on the vehicle and stabilizer design, it may help reduce:
- Steering wheel kickback over rough roads
- Unwanted steering movement from pavement grooves
- Driver fatigue caused by frequent corrections
- The effect of crosswinds and passing vehicles
- Steering movement following a front-tire failure
Safe-T-Plus steering control products use a self-centering design for supported motorhome, truck, and commercial vehicle applications. ShockWarehouse also carries selected steering stabilizers and kits for trucks, Jeeps, and other vehicles.
A stabilizer can’t repair loose tie-rod ends, worn ball joints, a damaged steering box, incorrect tire pressure, or poor alignment. It also shouldn’t be treated as a permanent repair for Jeep death wobble.
Inspect the steering and suspension system first. Installing a stabilizer over worn parts may temporarily change how the symptom feels without correcting its cause.
Check the Brackets and Mounting Hardware
Some steering stabilizers include all required brackets and hardware. Others reuse factory hardware or require a separate vehicle-specific mounting kit.
Confirm everything included in the package before starting the installation. If the stabilizer itself matches the application but won’t mount, the problem may involve a missing bracket, sleeve, bushing, or hardware kit.
Air Suspension Parts and Coil-Spring Conversion Kits
Vehicles equipped with factory air or electronic suspension require a different approach. Depending on the application, you may replace the failed air components or convert the vehicle to conventional coil springs.
Arnott suspension products include new and remanufactured air suspension components for supported applications. Arnott also offers coil-spring conversion kits for selected vehicles.
A conversion kit may replace air springs, air struts, or other electronic suspension components with conventional springs and dampers. These conversions are often considered for older vehicles that have experienced repeated air suspension failures.
Before converting, consider the following:
- The vehicle may lose automatic load leveling.
- Adjustable ride-height functions may no longer operate.
- Ride quality may differ from the factory air suspension.
- Some applications need an electronic module to prevent warning messages.
- Not every conversion includes the same components.
Some remanufactured suspension products also require a refundable core deposit. The deposit and return process should be shown on the applicable product page. Don’t discard the original unit until you’ve reviewed the core-return requirements.
Don’t Forget Mounts, Boots, Bump Stops, and Hardware
Smaller components can determine whether a suspension repair feels complete. These parts may not receive as much attention, but they protect the new shocks and struts.
Inspect or replace the following parts when applicable:
- Upper strut mounts and bearings
- Shock mounts and bushings
- Dust boots
- Bump stops
- Spring isolators
- Bushing sleeves
- Mounting bolts, washers, and nuts
A collapsed bump stop can reduce usable suspension travel. A damaged dust boot can expose the piston rod and seal area to debris. A worn upper strut mount may cause noise, binding, or poor steering response.
Some shocks include new bushings, sleeves, washers, and nuts. Others reuse factory hardware. Never assume every required part will be in the box. Review the product listing and inspect the original components before beginning the job.
Some Chassis Parts May Need to Come From Another Supplier
ShockWarehouse focuses primarily on ride-control and suspension-upgrade products. The selection includes shocks, struts, complete strut assemblies, springs, sway bars, load-support products, steering stabilizers, and air suspension components.
General chassis wear parts, such as tie-rod ends, ball joints, wheel bearings, and replacement leaf spring packs, may not be available for your application. Control-arm availability is also limited and commonly tied to specific performance or lift systems.
If you’re planning a complete front-end rebuild, confirm every part before scheduling the work. Don’t assume that finding the correct shocks means every steering or chassis component is available from the same source.
This is particularly important with lifted trucks. Some lifts require upper control arms, track bars, extended links, brake-line changes, or other geometry corrections. Shock requirements are only one part of the complete suspension plan.
How to Check Suspension Part Availability
- Enter the complete vehicle information. Confirm the year, make, model, drivetrain, submodel, and suspension configuration.
- Account for modifications. Include the lift or lowering amount, added weight, wheel and tire changes, and any existing suspension upgrades.
- Search by part number when available. A confirmed manufacturer part number can provide a more precise starting point.
- Identify the actual symptom. Explain whether the vehicle bounces, leans, squats, wanders, clunks, or sits unevenly.
- For motorhomes, identify the chassis. Examples include Ford F-53, Freightliner XC, Workhorse W-Series, and Spartan chassis.
- Review package quantities. Confirm whether the product is sold individually, in pairs, or as a complete axle kit.
- Check what’s included. Look for mounts, brackets, bushings, sleeves, and installation hardware.
A VIN may help confirm certain vehicle details, but it won’t always identify aftermarket suspension modifications. Measure the current ride height and verify any lift or lowering equipment already installed.
Match the Suspension Part to the Problem
| Primary Complaint | Parts to Inspect or Consider |
|---|---|
| Continued bouncing after a bump | Shocks or struts |
| Excessive body roll | Sway bars, end links, and bushings |
| Rear squat under cargo or tongue weight | Springs or load-support products |
| Steering kickback or frequent corrections | Steering components, alignment, tires, and steering stabilizer |
| Sagging or leaking air suspension | Air components or a vehicle-specific conversion kit |
| Noise after replacing a strut | Upper mount, bearing, spring seating, hardware, or installation |
The Bottom Line
Shocks and struts are often the right starting point, but they can’t correct every suspension complaint. Body roll may point toward sway bars. Squatting under a load requires attention to springs, weight, and load support. Steering problems require a complete inspection before adding a stabilizer.
The best results come from diagnosing the symptom before choosing parts. Treat the suspension as a system, confirm what’s included, and verify every component against the exact vehicle.
Explore the ShockWarehouse catalog to find shocks, struts, sway bars, springs, load-support products, steering stabilizers, and air suspension components. If you’re unsure what fits, contact ShockWarehouse with your vehicle details, modifications, and the problem you’re trying to solve.
