1973-1987 Chevy C10 | Slam Your Square!

Full Suspension Solution  for C10 Square Body Trucks

 Now available, this C10 Square Body suspension upgrade for all four corners of your square body pickup has an all-new torque arm design for the 1973-1987 Chevy C10. With these all-new, engineered- from-scratch systems, truck owners can add modern performance to a pickup that was originally designed for utility, all without needing to remove the bed of the truck, although it is recommended for an easier process. QA1 engineered this unique bolt-in torque arm design which maximizes performance without the inherent binding issues of other four-link systems. 

Dialing in the stance will be easy with the adjustable coilover system—you can easily achieve 4 to 7 inches of adjustment below stock. The major benefit of the torque arm design is that each component is designed to perform one function. This provides superior control over suspension movement, resulting in a smooth ride and great handling characteristics.

“If you didn’t know better, you would never know you were driving a vehicle with a bed on it,” says Damien Brase, QA1 fitment technician and owner of a 1983 C10. “The ride quality and handling are nothing like what you would expect from a pickup. I never would have guessed it could handle as well as it does now.”

The drivability of your classic truck will be greatly improved with 7 degrees of added caster and a fully adjustable ride height thanks to the adjustable coilover shocks. When pairing the front and rear QA1 suspension systems, not only can you lower your C10, but you’ll also have that perfect level stance that you know you want. The multiple adjustability options let you tailor the QA1 system to create the performance you desire, so your truck can handle those corners and curves like a sports car.

Both front and rear systems use QA1 shocks, with the choice between our double or single adjustable shocks. All QA1 shocks are 100% dyno tested, serialized and proudly made in QA1’s Lakeville, Minnesota, facility. The suspension comes powdercoated with all necessary hardware for installation. Complement these systems with C10 sway bars from QA1 for an even more impressive ride.

We chose QA1 for our square body build for the simple reason that we wanted a painless, DIY installation with no wiring, running air hoses or dealing with leaky systems. Just a solid stance, a smooth ride and some really nice new parts for our truck! Over the next few issues, we will rip apart the suspension on this all stock squarebody and show you just how simple it is to have a corner carving, tire spreading squarebody. Let’s do it!
