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.
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: No factory 2-inch lift/no enhanced tow: Trekline 800250120. Enhanced tow: Trekline 800250114. Factory 2-inch lift + 4-inch block: Trekline 800250125.
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.
