About this part
3-Inch Steel Lift Blocks with 15.5-Inch Round U-Bolts, fitment-checked
Part 6539 is Rough Country's 3-inch rear block and U-bolt set built around fabricated steel blocks rather than cast ones, tapered to reduce driveshaft angle and drilled for a single 9/16-inch pin. The round U-bolts use a 5/8-inch thread with 3.625 inches of inside width and 15.5 inches of inside length. It does not fit models with overload springs, and it does not fit dually models.
