TheCamberKing F1 fabrications
i have tried contacting them via every way I can think of:
FB
eBay
direct email
im at a loss.
I get one time one word responses and then nothing.




Id rather have the poly anyway, they last longer, and have better road manners.

I don’t particularly like the double locking nut design of either as they tend to slip and twist under load. I’m about to take mine out to correct that as well as replace the shïtty cheap sphericals UPD ships with theirs. I might also add that the UPD arms contact the frame on full compression (and only on full compression) and damage the arms - my straight arms each have a 1/4” deep divot taken out of them. I’m going to have to grind down a frame edge while they’re out, and the arms may be trashed depending on what I see when I get them out. When I reached out to ask if they would replace just the arms, they were real dïcks about it, so UPD customer support is about as bad as it gets if that helps make your decision easier.

I hear the kmac ones have issues with noise and now as above the UPD contact the frame!
After I used loctite on all the nuts they seem to be pretty decent and they've been through quite a bit of abuse. Around 6-7 track days so far.
Customer service was great, I blew the end links and they replaced them, but blew them again later.
I also have the rear adjustable control arm and its held up. Had to use a tiny bit of blue loctite to prevent them from breaking loose.
