Thread: Need to shorten rack & pinion.....help

Tweet

You really need to study up on bump steer and it's causes. If the tie rods and lower control arms don't follow very similar arcs, you will have bump steer.

The pivot points of the inner tie rod ends and the lower control arm pivots need to be in very close relation to one another. If this rack is too wide at the inner tie rod ends, it will need to be narrowed on the center portion instead of the tie rods.

Hydraulic racks can be shortened, but it is difficult. A MII manual rack can be shortened relatively easy compared to a power rack. Can't say about others.

There are racks that have the tie rods connecting near the center of the rack and I have seen these used in some swaps. You would have to map out the geometry to see if they cause much unwanted steering movement.

I have also seen racks with special attachments on the ends that move the inner tie rod ends inward or outward to what ever position is needed.
