Important Fitment & Installation Notes:

- Verify rear shock travel after installation; longer shocks may be required.
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: 2011-2020 2500HD/3500HD blocks use 3-inch-wide leaf springs. Model-specific U-bolt match needs axle/spring measurement before direct-linking; do not infer from 1500/1500HD hardware.
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.
