Bump Steer Kit Bolt cross threaded.

dcolli10 · Jun 3, 2023

Anyone know where I can find a replacement 5/8 bolt that you would typically find in a bump steer kit. Last owner cross threaded the bolt and it flattened all the threads. Don’t want to buy a whole kit for the one part.

Speedway motors sells a bolt for a ford “pinto.” Don’t know if that has the same taper as the sn95 spindle where it mounts.

Kit I have is a UPR bump steer kit if that helps.

Was contemplating just drilling out the spindle and replacing with a straight 5/8 grade 8 bolt. Wondering if anyone has seen that done before.

You can drill out the spindles but have it done in a drill press, don't do it by hand. It's gotta be a true job and not a hack job.

I had a machine shop drill out my spindles many years ago to about 15.5 millimeters and the thing came out perfect with something like that same bolt you have there. Bumpsteer package I ultimately settled on was from Maximum Motorsports to use a straight bolt setup, rather than the tapered.

Another option, if you’re wishing to keep the tapered setup, is to have a machine shop make a new bolt.

I think if I was in that position I’d ask the shop to quote the new, tapered bolt, and also machining the spindle(s) and see what the price difference is. It’s not much to machine out the spindle for a thru bolt, but it also isn’t much to fire up a lathe and make that tapered bolt.
