I have TSS billet gears in my 6.2 supercharged Raptor and I pay $345.00
+$400.00 for installation, Ford performance part extremely overpriced, if you don't do any engine modification no necessary to upgrade the pump on the Voodoo engine.
I think it's just bad luck, I never been stopped with my GT350 in the city and even with the exhaust on the loud mode the cops even not bother to give a look.
altjx,yes the owner is a very cool guy I meet him few times . he is smooth talking guy that will make you believe that his product is superior and if there is an issue then it's somebody else fault.
from my previous experience with ARH don't expect much help from them ( i live 45 minutes from they shop and got terrible customer service for my Raptor and Corvette headers). eventually, I switched to Kooks.
