BUMP STEER ADJ. KIT, MUSTANG 79-93

• Corrects Bumpsteer that occurs when the Mustang's front end is lowered or raised from stock
• Fully adjustable kit replaces non-adjustable stock components with precision, aircraft-quality components that bolt into place with common hand tools
• Does not require the front spindles to be modified or drilled out
• Can also be used for easy, on-car toe adjustments
• Includes 6061-T6 billet aluminum adjuster tubes with anodized finish to resist corrosion, 5/8 rod ends and an assortment of adjustment shims

Bumpsteer Definition

Bumpsteer is the toe-in change that occurs as the front suspension travels through its vertical movement. The vertical movement comes from; cornering causing body roll, braking and nose diving or hitting bumps in the road. The problem is a matter of geometry. As the front suspension goes through its vertical travel, there are a couple of arcs that are defined. One arc is the radius defined by the lower ball joint as it pivots around its chassis mount. Another arc is the one made by the outer tire rod end that is attached to the steering arm. It is pivoting off the rack and pinion ball joints. When a vehicle has its front suspension lowered, it effectively changes the factory geometry causing these two arcs to work against each other. Any differences in these pivot locations will result in bumpsteer which is a sudden change in toe-in during vertical suspension travel. Once for example you hit a "bump" the car "steers" somewhere other than where it was intended to go. The result is a car that darts from one side to the other, without any driver input into the steering. As the car goes faster, the effect becomes more violent. This kit is designed to correct the inherent weaknesses in the factory front suspension effectively eliminating "bumpsteer." Competition Engineering has developed this kit to correct bumpsteer, which allows you to shim the outer tie rod away from its steering arm mount to equal out the arc of travel with the lower control arm. We have also included a precision rod end and billet aluminum link to replace the failure prone factory tie rods and split sleeves.

NOTE: RE-ALIGNMENT AND TOE-IN ADJUSTMENT IS MANDATORY AFTER INSTALLATION!
