Important Fitment & Installation Notes:
- U-bolts are not included; verify the required diameter, width and length for the application.
- Longer rear shocks are required for this lift height.
- Offset center pin is built into the block; confirm axle position and factory block arrangement before installation.
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
Choose the U-bolt set by vehicle configuration: Crew Cab spans multiple GM generations/configurations. 1999-2006/2007 Classic: 2WD Trekline 800250099, 4WD Trekline 800250105. 2007-2018/2019 Classic: Trekline 800250109. 2019-2023 New Body: enhanced-tow Trekline 800250114; no enhanced tow Trekline 800250120; factory 2-inch lift uses configuration-specific set (4-inch added block = Trekline 800250125 if measurements confirm).
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.
