UCA shafts with 'Shelby Drop' built in

Not an original idea but we are now offering CNC machined drop shafts with the popular 'Shelby Drop' built in.

These shafts are machined from 4140 so are super durable. They are available as an upgrade to new orders as well as a retrofit option to existing customers.

Skip drilling holes, bolt these to the factory holes and the UCA is set to the 'Shelby Drop' specifications.

Shaun - for the control arm, how ‘short’ can the heims be adjusted vs the stock arm? I have a bit of a mess going on in the shock tower, the PO added some odd bracing, that isn‘t helping my suspension geometry. The added rectangular plate is pushing the upper control arm further out. Secondly, that lower brace is preventing me from doing the 1” drop.

This wasn’t noticeable with my skinny tires, but now with 235s, I’m getting some rubbing, even with the fenders rolled flat.

I know long term, the shock tower needs to be cleaned up, but was thinking that if for now, I can run the shorter upper arm, at least I could avoid the rub, and maybe get a reasonable alignment.

It’s a 1968, running new stock upper and lower control arms, Drake perches, Drake 1” springs with half coil cut, stock strut rods. Thanks in advance!

Thanks Shaun, understood. I‘d estimate the thickness is about 1/8” to 3/16”. Would your arms be able to be shortened this amount by adjusting the heim? Thanks!
Thanks Shaun. I may go part by part, starting with the UCAs, see what those do first. Thanks!
