The QA1 tubular LCA’s are better quality than the factory LCA’s ever were. Hands down a better design and better build quality.
It probably had more to do with the tolerances actually being correct, as opposed to factory loose.
The rubber bushings sold now won’t last 40 years. The MOOG rubber set of LCA bushings I ran on my Challenger didn’t last 4, one was completely thrashed before the 40k mile mark. The poly bushings I replaced them with still look brand new after 30k.
Properly installed the poly bushings will outlast any of the rubber bushings out there.
