If you are having problems with ARB's leaking it is installer error. I have never had a leaking problem and have been running them F&R since 98.
Hey OOPS,
I always enjoy your posts, and I know you’ve been on Earth for awhile.
But I think there’s enough history with the ARBs to indicate that they have or had an inherent failure-prone design. The guys I ran with that installed ARBs had problems and it wasn’t because of installer error – some the guys actually took steps above the recommended install instructions and were top notch mechanics and had the time and money to do everything right.
I have never had an ARB. But that’s just my experience with the guys I know who installed them.
Gnarls.
