Upgrade your 73-87 Square Body with the QA1 MOD Series Front Coilover Crossmember System for improved driving performance and a perfect stance. This complete system converts your Chevy C10’s front end to coil-overs and a tubular crossmember with rack-and-pinion steering. Enjoy up to 8” of adjustable ride height, enhanced drivability, and a weight savings of 140 lbs. over the stock setup.

Key Features:

Rack and Pinion Steering: Quicker, more responsive steering with a tighter feel and increased steering angle for larger wheels.
Increased Ground Clearance: Raised crossmember and control arms make the undercab frame rails the truck's lowest point, improving clearance.
Single-Adjustable Shocks: Fine-tune ride quality with easy shock valving adjustments, perfect for cruising or performance driving.
Easy Bolt-On Installation: The powder-coated crossmember installs with no cutting or welding required, making setup hassle-free.
Modular Engine Mounts: Choose from engine mounts (sold separately) for Small Block Chevy, Big Block Chevy, and LS applications, with DIY options for custom setups.

Optional Front Sway Bar: Add a front sway bar (sold separately) to enhance cornering and reduce body roll for increased grip.

Fitment Notes:

Retrofit kits available for existing QA1 coil-over systems.
Requires 1973-1987 C10 spindles and may need trimming of inner fenders.
At least 18” wheels are required for optimized bump steer settings with proper backspacing.
May require new headers, oil pan, and power steering hoses depending on engine placement.
