QA1 BW03-GMA3 Level 3 Big Wheel Suspension Kit 73-77 GM A-Body MOD Series

The QA1 BW03-GMA3 Level 3 Big Wheel Suspension Kit is a complete bolt-in suspension system engineered to fit larger 24" wheels on 1973–1977 GM A-Body vehicles. Designed for enthusiasts who want both a commanding stance and improved real-world performance, this kit delivers ride height adjustability, upgraded front-end geometry, and maximum shock tunability — all with straightforward, bolt-in installation.

MOD Series Coilover Performance:

At the heart of the Level 3 kit are QA1's flagship MOD Series shocks, featuring 4-way adjustable high- and low-speed valving for precise tuning across a wide range of driving conditions. Front and rear coilovers allow easy ride height adjustment — raise or lower the front to clear larger wheels, and adjust the rear from 0.5" above to 2" below stock ride height. The included spanner wrench makes height changes fast and simple.

Key Features:

• Complete bolt-in suspension system — no cutting or welding required
• 4-way adjustable front and rear MOD Series coilovers for superior ride and stance
• Rear ride height range: 0.5" above stock to 2" below stock
• Specially engineered control arms with corrected suspension geometry for big wheel fitment
• Adjustable trailing arms to center the rear axle in the wheel well
• Front and rear sway bars for improved cornering and handling
• Spanner wrench included for quick ride height adjustments
• Compatible with factory rear end housings
• Proudly made in the USA (Lakeville, Minnesota)

Big Wheel Geometry Correction:

QA1's specially designed control arms feature corrected suspension angles engineered specifically for big wheel builds. These arms are lighter and stronger than stock, improving drivability while providing the clearance needed for larger wheel and tire packages. Adjustable trailing arms center the rear axle in the wheel well for a proper fit.

Note: Some body styles may require fender modifications to accommodate the largest wheel sizes. Kits are compatible with factory rear end housings.
