Offset Upper Control Arm Shaft for GTO, Grand Prix, Lemans, and Tempest 1964-1972 #702

If you want to improve your handling, straight line stability and overall tire wear, you need to install a set of offset upper control arm shafts from Global West Suspension. They are designed to fit upper control arms for the GTO, Grand Prix, Lemans, and Tempest--model years 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, and 1972.

Generally, whenever we are rebuilding a stock front end, we will install offset shafts every time.

Why use offsets?

Offset upper shafts are used for several reasons:

• Repair alignment because of frame damage or frame sag.
• Repair alignment due to ride height change.
• Fine tune alignment for racing or performance street applications.

The Global West Advantage:

• By rotating the offset shaft in the control arm when you install it, you can push the tire towards the fender (positive camber) or in towards the motor (negative camber) to fix the wheel alignment. Another advantage of using the offset shaft is to gain more caster. Caster will help out the front end tremendously.

For most conditions, offset shafts are used for frame issues. They generally give you about 1-1/4 degrees of addition adjustment. However in the performance world, they are perfect for getting the best possible alignment using stock suspension.

One of the keys to better tire life and performance on these older muscle cars is to increase caster and induce some static negative camber. In fact you want to do this because more caster is going to give the car straight-line stability, faster steering response, and greater feel. Then add some negative camber to the mix and your tire life will improve; the offset shaft will allow you to do that.

Drag Racing:

The main advantage for using offset upper control arm shafts on drag cars using stock upper control arms is more positive caster. Positive caster will give you stability at high speeds. The offset shaft allows you to add shims to the back bolt on the upper control arm shaft and increase caster while maintaining camber. You can't get the caster you need without them, camber will be to much negative.
