Chevelle Ackermann and Bump Steer Kits

Wouldn’t it be great to have a little extra edge when turning into a hard corner? Well if you have ATS AFX tall spindles on your ’64-72 Chevelle now you can! Our Ackermann kit lengthens the steering linkage assembly and increases turn-in steering angle on your inside tire, see illustration below. Although it doesn’t affect straight line driving it can help pull you through the corners faster, increasing corner speeds and reducing your lap times.

Kit # 30522 below is based on a specially machined ATS AFX spindle billet steering arm that takes the place of the standard ATS billet steering arm, and pushes the tie rod end pick up point outward to increase Ackermann. It also includes a special longlength billet adjuster sleeve and our spherical bearing type tie rod end and bump steer correcting kit. If you already have AFX spindles on your car it’s an easy swap to convert to the new arm, or if you’re buying spindles now and you’re wanting the extra Ackermann advantage, be sure to order these special arms along with your Spindle kit.

Kit #30522 Includes:

Ackermann enhancing steering arms machined for shoulder bolts rather than tie rod pins
Long length billet tie rod adjuster sleeves, 5/8″ for ’64-70 cars
Spherical bearing type outer tie rod ends
Bump steer tuning shim kit and tie rod end shoulder bolts
***WILL NOT FIT 17″ WHEELS OR SMALLER****

You’re building your car for better control right? The last thing you need is bump steer, a condition when the car steers itself without driver input. This condition typically happens when the suspension bumps over uneven surfaces in the road or while in suspension compression through the turns. When your steering linkage and the suspension travel in different arcs the steering linkage will push or pull on the spindle’s steering arm making the car feel twitchy and unpredictable. Improper bump steer geometry can also cause opposing steering as you turn into a curve and the car starts to body roll.
