my old 2001 silverado 4x4 , first i ran just a 3 inch body lift and 35x12.50s on the stock rim with NO RUBBING AND NO TRIMMING OF ANYTHING!!!! i eventually ran a wider rim 16x8 moto metal and i added a 2.5 leveling kit from READY LIFT. i had to trim the valance at an angle and trim just a lil bit of the inner plastic. AND THIS IS FOR ALL U PEOPLE ON HERE WHO SAY THEY WONT FIT OR WHO SAY U NEED A 4 OR 6 INCH SUSPENSION LIFT TO RUN 35's! ALL THAT MATTERS IS U NO WHAT UR DOIN, AND MY 01 DID NOT RIDE ROUGH AT ALL. IF RODE GREAT!!!
