Here is a basic overview of the traction bars with shock relocation for first and second gen Camaros. -This traction bar kit also moves the shocks to the rear of the housing to the inside of the springs. It comes with the parts to move install the shocks at both ends- the chassis and traction bar spring plate. -67-69 Can use the long upper shock mount to match the shock location for an offset spring- this means you have moved the rear of the spring inboard approx. 1.75" to straighten them out. The long shock mount will allow for the proper spacing of the shock on the spring plate. -70-81 Camaros don't benefit from offsetting the rear of the spring the same way the 67-69 do. This means the standard short shock mount will be included with the 70-81 years. -Standard Rod end supply rod ends, machined spacers, fine thread hardware, powder coated black and your choice of how many front pivot holes- 1 or 3.
