Hey guys! Im new to the site. Need help making a decision. I have a 96 Tahoe 4x4 2door & want to put a lift to run 33x12.50x17 on 17x9 wheels. It is factory height now with 285/75/16's on factory wheels with no scrubbing. Do I really need a 4inch lift to run 33's? would a set of 3 inch coil springs and rear blocks be enough? If not, what is the best lift for the least $..? please help!
