By nature, the GM 4-link rear suspension performs well in straight-line situations—but it leaves a lot on the table when it comes to handling. The stock setup suffers from suspension bind, geometry changes under load, and weak stamped-steel control arms. Speedtech’s Complete Rear Suspension with Coilover Conversion for the 1994–1996 Impala SS fixes those problems with a fully engineered system designed for builders who want superior cornering, traction, and stance. This is the ultimate bolt-in upgrade for high-performance B-Body builds.
Performance & Handling Reimagined
Speedtech’s B-Body rear suspension system delivers modern performance by addressing the core issues of the factory 4-link. Adjustable upper and lower trailing arms with a combination of rubber bushings and rod ends eliminate binding and maintain consistent geometry through suspension travel. The kit also relocates sway bar mounting points for better leverage, giving the car flatter cornering and more predictable response. Paired with QA1 adjustable coilovers, this setup provides tunable ride height and damping for everything from street cruising to aggressive track use.
Bolt-In Engineering
This complete rear suspension system installs using factory locations -no cutting or welding required. Each component is CAD-engineered and laser-cut for a precise fit, with all Grade 8 hardware included. Builders can fine-tune pinion angle, wheelbase, and ride height for a perfect setup. Speedtech’s coilover conversion brackets are designed to work with factory GM-style shock mounts, making installation simple and reliable for professional shops or skilled DIY builders alike.
