QA1 SS304-07850 Spring Slider Kit 850lb/in GM F-Body with K-Member

The QA1 SS304-07850 Spring Slider Kit is a high-performance front suspension upgrade engineered for the 1982–1992 GM F-Body platform. Designed to work in conjunction with the QA1 tubular K-member and QA1 Pro-Touring lower control arms, this fully bolt-in kit transforms the front suspension geometry for improved handling, adjustable ride height, and significantly greater negative camber capability.

The spring slider assembly retains the factory inboard spring location while leveraging the combined strength of the frame and lower control arm to support an aggressive 850 lb/in spring rate—making it ideal for high-demand performance and track-oriented builds. The inboard spring positioning also enhances tire clearance, accommodating wider wheel and tire combinations.

Key Features:

• 850 lb/in Spring Rate — supports the heaviest spring loads for the most demanding performance applications
• Inboard Spring Relocation — retains factory spring location for maximum frame and control arm load support; improves tire clearance for wider wheels
• Adjustable Ride Height — allows precise ride height tuning to meet specific performance or stance requirements
• Aggressive Negative Camber Adjustment — enables greater camber range compared to standard coilover strut setups for improved cornering grip
• Heavy-Duty Steel Construction — black-finished steel spring sliders built for durability under high-load conditions
• Fully Bolt-In Design — no welding required; straightforward installation when used with compatible QA1 components
• Sold as a Complete Kit — includes all hardware needed for installation with the QA1 K-member

Installation Notes: Requires the QA1 tubular K-member and QA1 Pro-Touring lower control arms. A strut is required for alignment and dampening — this kit does not include or replace a shock absorber. For maximum negative camber performance, pair with QA1 struts and caster/camber plates.
