QA1 BW02-GMA3 Level 2 Big Wheel Suspension Kit 73-77 GM A-Body

The QA1 BW02-GMA3 is a complete Level 2 Big Wheel bolt-in suspension system engineered to accommodate larger 24-inch wheels on 1973–1977 GM A-body vehicles. This comprehensive kit delivers improved ride quality, adjustable stance, and upgraded handling—all without cutting or welding.

Double-Adjustable Coil-Overs — Dial In Your Perfect Stance

Front and rear double-adjustable coil-overs allow you to fine-tune ride height with precision. Raise the rear up to 0.5 inches above stock or drop it up to 2 inches below stock. Use the included spanner wrench to lock in your desired stance in minutes. Individually tune compression and rebound damping to optimize ride comfort or maximize traction off the line.

Engineered for Big Wheels Without Rubbing

Upgraded tubular front control arms feature corrected suspension geometry specifically designed for large-diameter wheels and tires. These arms are lighter and stronger than stock, improving front-end drivability while providing the clearance needed for 24-inch fitment.

Adjustable Trailing Arms for Rear Wheel Centering

Adjustable rear trailing arms allow you to precisely center the rear axle within the wheel well, ensuring proper clearance and eliminating rubbing with larger wheels.

Front & Rear Sway Bars for Improved Handling

The included front and rear sway bars reduce body roll and improve stability—addressing the handling challenges that come with running larger wheels and modified ride heights.
