1968-1972 GM A Body Bump Steer Kit

FSA1673 · 11-23-2023, 11:21 AM

Anyone make a bump steer kit for this type of chassis that raises the outer tie rod. All kits I can find seem to lower the outer tie rod. Based on my measurements I need to raise the outer tie rod about 0.5 inches to reduce bump steer.

Speedway motors kit is for a pinto type spindle.

All the other kits are designed to lower the tie rods from my understanding.

what you need and want are anti dive bars, designed by Larry Pappas

anti dive bars? You mean the cross shafts on the upper control arm?

I guess these are legal. My outer tie rods needed to be raised to reduce bump steer. Already had the Weibe anti dive cross shafts.

I can't image why you are having a bump steer issue, I never did.

Just trying to get every last thousand of ET out of it. Toe changes about 1/4" each side as currently set up from full compression to full extension. Wheels shimmy a bit when landing from wheel stand. Might be nothing there.

It looks like Global West also has its own.
