Kit Contents

• 2 rear suspension blocks.

Installation

The blocks install beneath the leaf springs, between the springs and the rear axle spring seats. The supplied U-bolts and hardware secure the assembly.

Shock length and clearances must be checked for the vehicle’s configuration and final suspension height.

Block Height and Actual Lift

The 3-inch measurement refers to the nominal block height. When replacing an existing block, the change in ride height is the difference between the two blocks. A 3-inch block therefore does not necessarily provide 3 inches of additional lift.

Warranty

The KINGROCK KR-2410 kit is backed by a lifetime warranty.
