Aftermarket Suspension Parts & Kits

Aftermarket suspension systems improve handling, ride quality, and ride height adjustment beyond what factory suspension provides. From lowering springs and coilover kits for sport handling to lift kits and leveling kits for truck and SUV off-road capability, quality suspension components transform how a vehicle rides and handles. Sport car and performance vehicle owners upgrade for reduced body roll, sharper turn-in, and adjustable ride height. Truck and SUV owners upgrade for load-carrying capacity, tow stability, off-road articulation, and larger tire fitment.

Suspension is the highest-leverage handling upgrade on any vehicle. A properly matched shock, spring, and sway bar package produces measurable improvements in cornering grip, transient response, and ride quality that no amount of engine, exhaust, or wheel work will replicate. It is also the modification most affected by installation quality and post-install alignment  plan for a professional four-wheel alignment on the same day as any suspension change.

Coilovers vs Lowering Springs vs Shock & Spring Kits

Choose the right suspension configuration based on how the vehicle is used, the budget, and the level of adjustability required.

Coilovers

Complete shock-and-spring assemblies with adjustable ride height set by threading the spring perch on the shock body. Coilovers replace both the factory strut and spring and offer the most flexibility for ride height, spring rate, and damping tuning. Available in single-adjustable (rebound only), double-adjustable (rebound and compression), and triple-adjustable configurations for street, track, and race use. Top brands include KW, Ohlins, BC Racing, Silvers, Fortune Auto, HKS, TEIN, Feal, MCS, and JRZ.

Lowering Springs

Drop-in spring replacements that lower the vehicle a set amount when used with the factory shock absorbers. Lower cost and simpler install than coilovers, but without adjustability. Recommended when the factory shocks are still healthy and the goal is a moderate 1-1.5 inch drop for improved appearance and mild handling gains. Top brands include Eibach, H&R, Swift, RS-R, and Vogtland.

Shock & Spring Kits

Matched shock and lowering spring pairs from a single manufacturer, tuned together for correct spring rate and damping. A step up from mixing standalone lowering springs with factory shocks, and a step below full coilover adjustability. Common examples include Bilstein B12 Pro Kit, KW Variant 1 (fixed height coilover), and Koni matched packages.

Lift Kits, Leveling Kits, and Truck Suspension

Lift kits raise trucks, SUVs, and Jeeps 2 to 12 inches for larger tire fitment, off-road clearance, and appearance. Leveling kits raise only the front to match a factory rear ride height, allowing a modest tire size increase without a full lift kit. Available lift components include lift springs, spacer kits, extended shocks, replacement control arms, drop brackets, extended brake lines, sway bar drop kits, track bars, and pitman arms.

Top lift and leveling brands include ICON Vehicle Dynamics, BDS Suspension, ReadyLIFT, Rough Country, Skyjacker, Zone Offroad, Pro Comp, and Fabtech. Confirm year, make, model, cab and bed configuration, factory suspension type, and any pre-existing modifications before ordering.

Sway Bars and Anti-Roll Kits

Sway bars reduce body roll during cornering by tying the left and right suspension together through a torsion bar. Aftermarket sway bars offer thicker bar diameters, adjustable mounting positions, and matched-pair sets for front-and-rear balance tuning.

Aftermarket sway bars are the single most cost-effective handling upgrade on most vehicles a modest investment produces immediately noticeable reduction in body roll and improvement in transient response. Top brands include Eibach Anti-Roll Kit, Whiteline, Hotchkis, Cusco, Steeda, and Progress Group.

Control Arms, Tie Rods, and Ball Joints

Adjustable and billet control arms replace factory stamped-steel or bushing-loaded arms for increased strength, adjustable camber and caster, spherical bearings for reduced deflection, and correcting suspension geometry after ride height changes.

Tie rods, tie rod ends, and heavy-duty ball joints replace worn or under-spec factory components on high-horsepower, off-road, and heavy-load applications. Confirm thread pitch, taper size, and mounting-eye dimensions.

Featured brands include SPC Performance, Moog, Whiteline, Mevotech, ICON, RCV Performance, and Black Ops Auto Works billet control arms.

Bushings and Bushing Kits

Polyurethane and spherical bushings replace factory rubber bushings for reduced deflection, sharper handling, and longer service life on high-mileage and heavily driven vehicles. Available as single-component replacements, subassembly kits (control arm, sway bar, differential), and full-vehicle bushing kits.

Polyurethane bushings offer a balance of durability, reduced deflection, and street comfort. Spherical bushings offer the sharpest response and the least deflection but generate more noise, vibration, and harshness. Rubber bushings offer the best isolation from road noise but the most deflection.

Top bushing brands include Energy Suspension, Prothane, Whiteline, Powerflex, SuperPro, and Daystar.

Alignment Kits, Camber Kits, and Caster Kits

Alignment adjustment hardware is required to restore correct camber, caster, and toe settings after ride height changes. Available hardware includes camber bolts, camber plates, adjustable ball joints, adjustable control arms, adjustable tie rods, and caster/camber offset bushings.

Vehicles lowered more than 1 inch or lifted more than 2 inches typically cannot be aligned to factory specifications with factory hardware alone. Plan on ordering the appropriate adjustment components before the alignment appointment. Top brands include SPC Performance, Ingalls, Eibach Pro-Alignment, Whiteline, and Moog.

Air Suspension Systems

Air suspension kits replace factory springs and shocks with airbag-and-shock combinations that allow ride height to be adjusted on the fly from a controller inside the vehicle. Available for lowering (show, static-drop appearance), leveling (load-carrying, towing), and lift (off-road ground clearance) applications.

Air suspension components include air struts and airbags, air compressors, air tanks, air lines, pressure sensors, height sensors, and management controllers. Top brands include Air Lift Performance, Air Lift Company, Firestone Ride-Rite, AccuAir, Universal Air, and Ridetech.

Chassis Bracing and Strut Bars

Chassis bracing reduces flex in the vehicle body and subframe under cornering, braking, and acceleration loads. Available products include front and rear strut tower bars, subframe braces, sway bar reinforcement plates, undercar cross braces, and structural chassis stiffener kits.

Chassis bracing produces the largest improvement on unibody sports and performance cars with removable roof panels or a convertible body style, where factory chassis rigidity is inherently reduced. Top brands include Cusco, Ultra Racing, Beatrush, Hotchkis, and Black Ops Auto Works billet strut braces.

Shocks and Struts

Aftermarket shocks and struts replace worn factory dampers with performance-tuned or heavy-duty units. Categories include OE-replacement shocks (matched to factory ride height and rate), performance shocks (firmer damping for sport handling), lifted-truck shocks (extended length for lift kits), and off-road shocks (large bore, remote reservoir, adjustable damping).

Top brands include Bilstein B6/B8/5100/6112, KYB Excel-G and Gas-a-Just, Koni Yellow (Sport), Red (Special), and STR.T, Fox 2.0 and 2.5 Performance Series, KING Off-Road, Radflo, and Icon Vehicle Dynamics.

Steering Components

Steering components include steering racks, steering knuckles, spindles, steering dampers, and steering stabilizers. Available upgrades include quick-ratio steering racks, billet spindles for track and drag racing use, heavy-duty steering dampers for lifted trucks and Jeeps with large tires, and dual steering stabilizer kits for off-road stability.

Steering dampers reduce shimmy and bump-steer on lifted and off-road vehicles running large tires. Top brands include Fox ATS, ICON, Rancho RS9000XL, and Bilstein 5160.

Common Questions About Suspension

What is the difference between coilovers and lowering springs?

Coilovers are complete shock and spring assemblies with adjustable ride height set by threading the spring perch on the shock body. They replace both the factory strut and spring and offer the most flexibility for ride height and suspension tuning. Lowering springs are drop-in spring replacements that lower the vehicle a set amount when used with the factory shock absorbers, at a lower cost but without the adjustability of a full coilover kit.

Do I need an alignment after suspension upgrades?

Yes. Any change to ride height, spring rate, or suspension geometry requires a professional four-wheel alignment to restore proper camber, caster, and toe settings. Driving on a misaligned suspension after a ride height change causes accelerated tire wear and can negatively affect handling stability. A full four-wheel alignment is recommended immediately after any suspension modification is complete.

How much can I lower my car without buying camber kits?

Most vehicles can be lowered approximately 1 inch on factory alignment hardware without exceeding manufacturer camber and caster specifications. Beyond 1 inch of drop, adjustable camber plates, camber arms, or camber bolts are typically required to restore correct alignment. Confirm with your alignment shop before purchase whether adjustment hardware is required for the target ride height.

How much lift can I add without new control arms or drop brackets?

Most trucks and SUVs accept 2 to 3 inches of lift on factory control arms and factory brackets before geometry issues appear. Beyond 3 inches, upper control arms, drop brackets, or extended-length components are typically required to maintain correct ball-joint and CV-joint angles. Confirm the lift kit manufacturer's recommendations before purchase.

Are coilovers OK for daily driving?

Yes, quality coilovers from Bilstein, KW, Ohlins, BC Racing, Silvers, and similar manufacturers are designed for daily street use with adjustable ride height and damping. Race-only single-purpose coilovers with very high spring rates and limited damping range are not recommended for street use. Match the coilover series to the intended balance of street comfort and track performance.

What is the difference between a strut and a shock?

A strut is a structural suspension component that carries the vehicle weight and locates the wheel, integrating a shock absorber inside the strut body. A shock absorber is a damping-only component that does not carry weight or locate the wheel and works alongside a separate coil spring or leaf spring. Most modern front suspensions use struts; most modern rear suspensions use separate shocks and springs.

Can I mix and match brands of shocks and springs?

Yes, but matched shock-and-spring kits from a single manufacturer (Bilstein B12, Koni STR.T + Eibach, etc.) are engineered together for correct spring rate and damping and generally produce better results than mixing standalone components. If mixing, select shocks with damping matched to the target spring rate and lowered ride height.

How long do aftermarket shocks last?

Quality aftermarket shocks and struts typically last 50,000 to 100,000 miles under normal street use. High-performance coilovers driven on the street and track often benefit from a rebuild every 20,000 to 30,000 miles or every 1 to 2 years of hard use.

Do sway bars affect ride quality?

Larger aftermarket sway bars mildly increase ride harshness on rough single-wheel bumps because the stiffer bar transfers more motion between the left and right suspensions. On smooth roads and in cornering, they primarily reduce body roll and sharpen turn-in with minimal impact on straight-line comfort.

What is a shock & spring kit vs a coilover kit?

A shock & spring kit is a fixed-height matched pair (shocks + lowering springs) engineered to work together. A coilover kit is a fully adjustable ride-height-and-damping assembly. Shock & spring kits offer a matched setup at a lower cost; coilovers offer adjustability at a higher cost.
