If you have lowered your vehicle or altered the geometry through a control arm relocation kit or our X2 Balljoints, X5 Balljoints then you have increased bump steer which needs to be corrected.
Steeda's Bump Steer Kits have a wide adjustment range for bump steer correction and feature spherical rod ends and use tapered spindle studs for a hassle free installation.
Don't buy inferior kits that require you to ruin your spindle by drilling it out in order to install them. Do it right with Steeda's Bump Steer Kit.
Bump Steer Definition: Bump steer is a change in toe angle caused by the suspension moving up or down. Bump steer is built into the geometry of the suspension and steering system, and occurs independent from any steering wheel input. The effect of bumpsteer is for the wheel to toe-in or toe-out when the suspension moves up or down.
This toe change or "steering" occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Excessive bump steer that occurs from lowering or altering suspension geometry is undesirable because the suspension is giving you unwanted steering inputs from the excessive toe changes.
