Aluminum, threaded body, single adjustable mono-tube QA1 shocks
Hyperco high silicone ire coil spring
The spring coiling the shock means that the shock and spring operate at the same rate regarding the wheel rate. This makes it easier to understand why a change in one has a certain affect. Placing the coilover closer to the axis center line will have a spring and shock rate closer to the wheel rate. This enables you to respond quicker to the wheel movements and it's more sensitive smaller movements. Furthermore the shock is more rigidly mounted for maximum durability of the package. The spring's rate is designed to optimize the suspension movement very closely. The shocks are rebuild-able, re-valve-able, and generally much higher quality than OE shocks. They absolute true independence and allow you to fine tune the rear suspension much closer. Unlike the transverse leaf which reduces the true independence.
NOTE: 1963-64 Cars need to convert to disc brakes. Will not work with drum brakes.
