1971-72 Bolt In Adjustable Upper Torque Box Assembly

Ever wanted more adjustability out of your A-Body? This assembly is completely bolt-in and very easy to install. It provides a wide range of adjustment to dial in your instant center and anti-squat, helping your car launch harder and track straight.

This setup bolts in using the factory upper control arm mounting holes. No welding is required. Only four holes (two per side) need to be drilled to secure the torque boxes to the frame.

• No cutting or grinding required on the frame

• Requires shorter upper control arms (kit-specific arms available, or you can have your existing arms shortened — see A-Body products)

• Optional bolt-in center cross brace available

• Optional bolt-in side braces available

• Powder-coated options available

Outer braces are supplied unwelded.
