hey mate, I have a 2 inch lift with rancho quicklifts. I just bought some 2 inch round blocks of steel with the right size hole drilled through it.Might be alloy. i have not had to change anything with this lift and have not had any dramas at all.Its still very high and tough looking, with out having to change control arms etc. Have just put in all new ball joints so will see if the lift damages these over time.I have a telescopic steering arm so not sure if yours is the same as ive read on here that some people have had issues with steering and have had to change theirs to telescopic. its a great job doing the lift, worth it but a bit of work. so be patient.there is a full write up on here somewhere and that is what i followed and perfect result.i have just given my black beast a full re birth eg. engine out and all new timing chains and bits and pieces (big job) transmission fully rebuilt, all new rotors pads, ball joints, control arm rubbers, new roof rack with 5 hela black magic spotlights, just waiting for black rims from the states and going to run 285 70 r16 . custom bull bar to come .any way, go the 2 inch looks tough without being to damaging to your truck. cheers from oz
