Lift-block height is not always the same as net vehicle lift when a factory rear block is already installed. If a factory block is removed, subtract its thickness from the new block height to determine the approximate net increase. After installation, verify U-bolt torque, brake-line clearance, driveline angles, shock travel and tire clearance.
Complete Your Installation — U-Bolts Required
U-Bolt Selection Requires Measurement: 1973-1991 C10/K10/C15/K15 Suburban. Current exact standard/lift U-bolt SKU is not being inferred from flip-kit hardware. Link U-Bolts parent category and require axle/leaf-spring measurement.
Search Serial Killer Customs U-bolts and match the required dimensions to the truck before ordering.
Fitment safeguard: Always measure before ordering U-bolts. Verify bend style, bolt diameter, inside width, overall length and usable thread against the actual axle and leaf-spring pack. Factory options and previous suspension changes can alter the required dimensions.
