A 4-link suspension system is commonly used to replace leaf springs and shocks in vehicles to provide much greater stability while cornering, greater tire contact and traction for drag racers, and reduces body roll in lifted off-road trucks and SUVs. Four-link kits create a definitive center for a rear suspension, and are commonly used with a Panhard or track bar to improve vehicle handling because it lowers your off-road vehicle’s center of gravity.

4-Link Kit for Trucks and Off-Road

A 4-link rear suspension system provides many performance advantages and longevity over a leaf-spring setup for intense off-road use or street vehicle. Whether you’re driving a Jeep Wrangler YJ, a Chevy S10 or C10 pickup, or Ford Bronco, Summit Racing carries several 4-link kits for trucks and SUVs. Four-link systems attach to the rear axle, and the center of your truck or SUV to let the axle articulate over rough terrain while significantly reducing the impact on the body of the vehicle. That reduces a ton of wear on various parts, and dramatically improves ride quality for drivers and passengers.

4-Link Kits for Drag Racing

Four-link brackets offer flexibility to set up your racecar’s 4-link instant center (or IC) in the location that provides maximum hookup and acceleration for your specific vehicle to help you win a lot of races. Four-link kits are available with or without crossmembers, and with or without diagonal links included. Summit Racing has everything you need to build the triangulated or parallel 4-link suspension setup you want.
