One thing I would try to avoid in tubular UCA’s is heim joints. I have a set of Hotchkis UCA’s on my Challenger, which have heims. The first set lasted only 7k miles before being wiped out. That was without boots on the heims. Hotchkis replaces those heims for me, and sent a set of boots. But 7k miles later, they’re showing wear again and probably won’t make 10k.
Now, I’ve used heims at the strut rods, and they’re like new after 70,000 miles on my Challenger. But I don’t like heims at the UCA on a street car. Just my opinion.
QA1, PST, Firm Feel, and Bergman Autocraft all make tubular UCA’s with extra caster built in (or adjustable in the case of Bergman Autocraft) that also use bushings.
