Adjustable Bump-Steer Spindle Adapter - GM Spindle Taper
This is the 4140 chrome moly spindle adapter
only for those that are building a bump-steer kit for custom
applications or those who have purchased a bump-steer kit that requires drilling out the spindle. Many bump-steer kits on the market do not come with a spindle adapter
that is machined to be a direct fit to the GM spindle taper but rather simply come with a 5/8" bolt and you have to drill out the spindle's tapered hole to 5/8". We
understand no one wants to do that so we now offer just our bump-steer spindle adapter that you can then use with your existing bump-steer kit.
Altering ride height can result in unwanted toe change during suspension travel. This is known as bump-steer.
Bump-steer kits allow the user to alter the outer tie rod position on the spindle to correct bump-steer.
This bump-steer spindle adapter comes with two 5/8"-18 RH jam nuts, one 7/16"-20 RH top lock nut and two 5/8"
safety washers. Our spindle adapters do not require you to drill out your spindle hole. Our bump-steer spindle adapters are CNC machined from 4140 chrome moly
and are machined to be a direct bolt on to the GM spindle taper. They feature a silver zinc plated finish for durability and a nice appearance.
They are on the car bump-steer adjustable. The bump steer spindle adapters are fully threaded with double locking jam nuts for easy up-down adjustment that eliminates the need for spacers. They feature 5/8” chrome moly safety washers that go on the top and bottom of your 5/8" rod end for adequate articulation and safety.
