The Essential Guide to Summit Suspension Parts: What You Need to Know

When upgrading your vehicle’s suspension, Summit Racing offers a wide selection of brand-name parts and their own house-brand components. This guide covers the key categories of Summit suspension parts, how to match parts to your driving needs, and practical considerations for a successful upgrade.

Why Choose Summit for Suspension Parts?

Summit Racing has built a reputation as a reliable source for performance parts. Their in-house Summit brand suspension components are designed to meet or exceed OEM specifications, often at a lower price point than premium aftermarket brands. They also carry parts from top manufacturers like Bilstein, Eibach, Moog, and KYB. Whether you need a simple replacement or a full coilover system, Summit’s catalog covers most domestic and import vehicles from the 1950s to current models.

Types of Summit Suspension Parts

Shocks and Struts

Shocks control spring oscillation and keep your tires planted. Summit offers gas-charged, twin-tube, and monotube shocks. For most daily drivers, their Summit brand gas shocks provide a comfortable ride at a budget-friendly cost. For performance driving, consider monotube designs from Bilstein or KYB. Struts combine the shock and spring into one unit – common on many front-wheel-drive cars. Summit lists strut assemblies that include the spring, making replacement easier.

Springs

Coil springs and leaf springs support the vehicle’s weight. Summit carries stock-height and lowering springs. Lowering springs reduce the center of gravity and improve cornering, but may stiffen the ride. For towing or heavy loads, consider air springs or helper springs. Summit also sells coil spring spacers and leaf spring bushings. When choosing springs, know your vehicle’s spring rate (lbs/in) and whether you want progressive or linear rate. Progressive springs offer a softer initial feel and more resistance under compression.

Control Arms and Ball Joints

Control arms connect the wheel hub to the frame. Upgraded arms often feature stronger materials, polyurethane bushings, and adjustment slots for camber adjustment. Summit offers upper and lower control arms for many trucks and muscle cars. Ball joints are wear items – inspect them when replacing control arms. Summit’s house-brand ball joints are a good middle-ground option. For off-road trucks, look for heavy-duty ball joints with larger studs.

Sway Bars and Links

Sway bars reduce body roll during turns. Summit sells aftermarket sway bars in various diameters (typically 1.0 to 1.25 inches) with stiffer bushings and adjustable end links. A thicker bar reduces roll more but may increase understeer. End links are often overlooked but must match the bar and vehicle. Summit’s polyurethane end links offer durability over rubber.

Bushings and Mounts

Rubber bushings isolate noise and vibration but degrade over time. Polyurethane bushings are firmer and more responsive. Summit carries full bushing kits for control arms, sway bars, and leaf springs. For track use, consider Delrin or spherical bearings. Note that polyurethane may squeak without regular lubrication.

Matching Parts to Your Driving Needs

Daily Driver

For a commuter, focus on comfort and longevity. Stick with OEM-style replacements from Summit’s house brand or Moog. A set of Summit gas shocks and stock-height springs will restore ride quality without breaking the bank. Avoid overly stiff components that cause jarring.

Street Performance

If you want sportier handling, go with lowering springs (1.0–1.5 inch drop), monotube shocks, and a thicker sway bar. Summit’s brand performance shocks are a solid entry. Pair with upgraded control arms to correct geometry after lowering. Adjustable camber plates can help align the front end.

Off-Road / Truck

For lifted trucks, Summit offers lift springs, extended shocks, and adjustable track bars. Focus on shock travel and valving. Fox 2.0 or Bilstein 5100 series shocks are popular choices sold through Summit. Add sway bar disconnects for better articulation. Summit also sells leaf spring shackles and add-a-leaf kits.

Track / Autocross

For competitive driving, precision matters. Coilovers from brands like QA1 or Viking allow adjustment of ride height, spring preload, and damping. Summit stocks these along with camber and caster plates. Lightweight aluminum control arms reduce unsprung weight. Consider spherical bearings in control arms for zero deflection – but expect more noise.

Installation Considerations

Most suspension parts require basic tools – jack stands, wrenches, a spring compressor for coil springs. If you lack experience with alignment, have a professional install. Improper installation can cause handling issues or premature wear. Torque all bolts to manufacturer specs. After installation, get a wheel alignment. Summit’s website often includes installation notes in the product description.

Final Recommendation

Begin by assessing your vehicle’s current condition and your goals. For a budget-friendly refresh, replace worn shocks and bushings with Summit’s house-brand parts – they offer good value. For targeted performance gains, invest in specific upgrades like a sway bar or lowering springs. Avoid mixing components that conflict in spring rates or damping. Use Summit’s customer service chat if unsure about compatibility – they can cross-reference part numbers.

Summit suspension parts provide a reliable path to improved ride and handling, whether you’re restoring a classic or fine-tuning a track car. Shop with confidence knowing their return policy covers defective parts. Always prioritize safety – if you’re not confident, have a certified mechanic handle the install.
