If there is some mismatching of the arcs that the wishbone and steering arm travel through during bump this will cause some unwanted steering arm movement. This steering arm movement causes 'bump steer' which reduces overall steering control and requires more steering input in cornering.
This kit can be used to eliminate or tune bump steer by replacing the track-rod end and spacing the outer fixing point using shims for fine tuning.
The kit includes everything you need to replace your track rod ends and tune bump steer:
Steering rack adaptors and lock nuts,
High performance PTFE lined rod ends,
20 x adjustment shims,
Spacers to allow full range of rod end misalignment,
High tensile bolts and nyloc nuts,
