Getting current technology is a lot easier than you think, especially with suspension. We offer several components that are designed to help your suspension handle modern tire science. The first step is to give the car some stability. This is done through geometry and alignment.
The upper control arms have the following:
The Global West Advantage: Why increase caster?
- More caster built in
- Improved camber curve for better handling and less tire wear
- Offset upper cross shafts
- Upper ball joints
- Bump stops
- Finish --- powder coated black
- New alignment specifications included
Caster provides straight-line stability to a vehicle; to achieve our goal, caster was built into the upper control arms to help improve stability at all speeds. 1958-64 Impalas never had enough available through standard alignment techniques.
In addition to our design, we installed Del-a-lum bushings and added width to the bushing dimensions so we could increase the holding capability of the lower arm with the sticker tires.
Standard ball joints are used for easy replacement down the road and these arms will work with stock lower control arms.
Global West also offers a special upper control arm that is longer for cars using airbags or hydraulics.Note:
We have placed the bump stops on the control arm rather than relying on them to be on frame because most cars have lost them.
