Bump Steer Kits

Easy adjustment to correct for bump steer

Bump steer - is a change in toe setting due to vertical wheel displacement. A car that bump-steers requires constant steering adjustment to maintain a steady trajectory over uneven surfaces. This can be handful to drive.

Bump steer becomes severe with lowered ride height and is extreme with spindle height modifications. It's easily corrected by spacing the end of the tie rod down. The correct spacing depends on ride height and spindle height, we make all our bump steer kits adjustable.

Toe steer - A second problem is introduced when a long bump steer spacer is used, as required on raised spindle cars. The long spacer acts as a lever to twist the steering knuckle. Beyond the obvious issue of strength, any twisting of the steering knuckle causes toe steer, and a required correction at the steering wheel to maintain steady trajectory.

We offer two adjustable bump steer kits; Our Racing kit is for cars with spindles of any height and resolves both bump steer and toe steer. Our Bolt-on Bump steer kit is for cars with spindle height ranging from stock to +19mm.

Racing Bump Steer Kit

Our top-performing bump steer solution is super strong and provides the sharpest, most predictable steering response. It eliminates steering knuckle twist induced toe steer. It can be used on raised spindles of any height.

Double steering knuckle - Holds tie rod end between two steering knuckles to eliminate knuckle flex regardless of bump steer spacer length.

Long bump steer spacers (required with raised spindles) place bending loads that twist stock steering knuckles. Twist causes undesired toe steer.

Second steering knuckle is welded to the strut body. You can optionally have us perform the welding for you.

Bump steer adjustable - allows massive bump steer adjustment range in .125 inch increments. Double shear mounting provides solid support for even the longest bump steer spacing.

Rod End - Weather sealed precision rods ends included work with regular turbo tie rods. Included boots to seal out dirt and and water for extended life.

Our purpose-made rod ends are extra long to ensure proper threaded engagement with standard turbo tie rods.

Spindle height - Kits available for 19mm, 30mm, 40mm spindle height. Kits are easily modified for use with essentially any spindle height.
