QA1 71-76 GM B-Body Level 1 Big Wheel Kit

QA1 71-76 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 specifically to support up to 28” wheel and tire combinations on 1971–1976 GM B-Body applications while restoring proper suspension geometry and shock travel.

Upgrading to 28” wheels significantly increases unsprung mass and suspension leverage. Factory geometry cannot properly maintain compression travel or control arm angle at this diameter without correction.

This Level 1 system restores shock stroke positioning within its proper operating range while providing threaded ride height adjustability to dial in stance and clearance.

Ride Height Engineering for 28” Builds

• Threaded-body ride height adjustment
• Restored compression and rebound travel
• Corrected control arm operating angles
• Reduced bump stop engagement
• Improved fender-to-tire clearance management

Included Components

• QA1 threaded-body adjustable front coilovers
• QA1 rear adjustable shock and spring system
• Heavy-duty spring rates engineered for 28” wheel mass
• Application-specific trailing arms (where required)
• Complete bolt-in installation hardware

Designed to allow large wheel fitment while preserving suspension function and street drivability.
