QA1 77-90 GM B-Body Level 1 Big Wheel Kit

QA1 77-90 GM B-Body Level 1 Big Wheel Kit

Fits up to 28” wheels

LEVEL 1 – BIG WHEEL SUSPENSION SYSTEM
Ride Height Corrected Street Package

Engineered to properly support up to 28” wheel setups on 1977-1990 GM B-Body applications.

28” wheels dramatically increase unsprung mass and change leverage against suspension components. Factory geometry cannot properly manage the added height and weight.

This system restores proper shock stroke range and control arm angles while allowing adjustable ride height for accurate stance control.

Ride Height Engineering for 28” Builds

• Threaded ride height adjustability
• Restored compression and rebound travel
• Corrected control arm operating geometry
• Proper fender-to-tire clearance management

Included Components

• QA1 threaded-body adjustable front coilovers
• QA1 rear adjustable shock/spring system
• Heavy-duty spring rates engineered for 28” wheel mass
• Complete bolt-in installation hardware

Built to allow large diameter wheel fitment while maintaining real suspension function and stability.
