1964, 1965, 1966 A Body rear coilover kit stock rear end using QA-1 single adj shocks

Global West manufactures two different rear coilover suspension kits for 1964, 1965, and 1966 Chevelle, El Camino, Monte Carlo, Gto, Lemans, Cutlass, 442, Skylark, and other A-body applications.

Both kits are used for street and racing purposes; however the major difference is where the shock mounts. The first kit Global West produced uses Penske racing shocks and the shocks mount before the axle.

This particular kit, the shocks mount behind the axle. They install approximately where the factory shocks are. The advantage to running the shock in the back is mostly cost. It is easier to install and no welding is required. The main advantages to using a coilover shock-spring combination verses the stock setup are adjustable ride height and multiple spring rate availability. Both coilover kits use a 2.5 id flat ground spring which is a standard size for many coilover applications.

Installation is fairly simple. No welding is required; you have to drill a few holes during the installation process and that’s it.

The Global West Advantage:

Instead of just bolting a coilover over shock and spring to the stock upper mount and moving the lower mount over for clearing the differential, Global West supplies an upper cross-member for taking the majority of the load. The cross member bolts close the factory frame rails and then picks up the original shock mount on the frame.

Note: When installing the shock to the new cross-member, an additional bracket (supplied in the kit) will bolt on the other side of the shock so that the shock attaching bolt is supported on both sides.

By doing it this way, we increase the load capability and put the bolt in double shear, which is the strongest way to attach the coilover shock. The lower shock mount is also placed in double shear. The shock mount bolts to the differential and moves the shock over away from the differential for spring clearance. To install, drilling a couple holes in the differential lower arm bracket is required.

Why use adjustable shocks:

This kit uses QA-1 single adjustable shocks. The shock allows you to adjust the firmness of the ride simply by turning the knob. The shock is best used for street or non racing environment. The shock has 19 adjustments from full soft to full hard. Ride height is adjusted by using a spanner wrench that is provided in the kit and rotating the threaded collar up or down on the shock body. This will raise or lower the car.



What comes in the kit:

This kit includes: Single adjustable Qa-1 shocks, 150 rate Eibach springs, cross member, shock mounts, brackets, and hardware.
