Just put a revtek 3" lift on my 01 tacoma. all went well, except I have a "hollow sounding banging" noise from my front suspension going over bumps. Is that to be expected since the factory rubber bumpers at the top of the coils are replaced with metal blocks, or is something not right? For those of you who don't know, the revtek lift is front and rear blocks; no new springs involved. Truck looks great though!!! Any info would be apprecciated, thanks James
