Chevelle Ackermann and Bump Steer Kit
Steering arms shown above are purchased separately from the bump steer kit.
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 '64-70 Chevelle now you can! Our Ackerman 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.
This kit is based on a specially machined ATS AFX billet spindle steering arm that takes the place of the standard ATS billet steering arm. If you already have AFX spindles and steering arms 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 (sold separately, order below) along with your Spindle kit.

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.
Fighting the car rather than having it go where you want it to can be frustrating while cruising and ruin your track times. The best way to resolve this is by dialing in your suspension geometry with our adjustable bump steer kit. By simply changing the stacking order of the varying height shims in the kit, (see example below), you can tune the steering linkage to eliminate much of the bump steer associated with factory settings and components. Compared to other brands our design uses a shoulder bolt rather than a pin/ bolt combo to allow greater wheel clearance and size options.
