SPC Upper Control Arm

There are several, but I ended up going with the Dirt King tubular ball uppers, because they use non-proprietary bushings and BJs, and I have been exceptionally pleased with my DK uniball lowers as well as their customer service.

Camburg also makes +caster UCAs as does TC, JD Fab, and several others - best bet is to find a retailer that stocks a bunch of manufacturers and look through the descriptions.

 

Mine are the old version non greasable. I bought them used in 2015. I've only had to replaces the bushings once. 76k mi on them no other issues. The guy I bought them off of had 36k mi on em.

 

Last arms I had were ones pre nov 2022 (got them under warranty around nov 2021). Still couldnt pay me to touch the "newest" ones with "better q/a and tolerances".

 

I'm at 240K km (150K miles) on my tubular SPC UCA's (bought end of 2012). I changed ball joint once (2018) to the greaseable model and I'm about to install my second set of Spec Ride bushings. Hopefully SPC goes back to the tubular model before I need another set of UCA'S, they seem to last quite a bit more than the newer models!

 

who is your contact at SPC?

I did the “upgrade” , from the old style to the axis bushings, 2 years ago when one of my ball joints was needing replaced, after close to 80,000 miles on them. Now right at 2 years and less than 20,000 miles and both ball joints are bad and there is some play in the axis bushings. I was emailing with Jack Stevenson at SPC and he seemed very helpful and acted like they would warranty them with new arms. He asked for pictures and video of them, so I sent them and have yet to hear back from him, it’s been close to 2 weeks.

I guess I need to call there or contact someone else. I’d really like to get them fixed before something happens.
