Upgrade your square body C10 with the QA1 73-87 C10 Single Adjustable Front Coilover Crossmember System for improved driving performance and a perfect stance. This all-in-one kit converts your Chevy C10's front end to coil-overs and a tubular crossmember with rack-and-pinion steering, offering up to 8” of adjustable drop and saving 140 lbs. over stock components.

Key Features:

Rack and Pinion Steering: Enjoy quicker, more responsive steering and increased angle for larger wheels, enhancing overall drivability and performance.
Increased Ground Clearance: The crossmember and control arms raise undercab frame rails to be the lowest point, ensuring maximum clearance while maintaining optimal shock travel for smooth performance at low heights.
Adjustable Ride Comfort: QA1’s single adjustable coilovers let you switch between a comfortable cruise and a more aggressive feel with a simple turn of the 18-position knob, making tuning easy.
Easy, Bolt-In Installation: The powder-coated crossmember requires no cutting or welding, ensuring a straightforward bolt-in process, and includes provisions for common engine mounts (sold separately).
Modular Engine Mounts: Available mounts allow compatibility with Small Block Chevy, Big Block Chevy, LS engines, and DIY customization for exact positioning.

Made in the USA: Proudly manufactured in Lakeville, MN, delivering the highest quality for your C10 truck.
