2 in Block and U-bolt Kit — Ford F-150 2021–2026

KINGROCK KR-2409 2-Inch Rear Lift Block and U-Bolt Kit — Ford F-150 2021–2026

Adjust the rear ride height of your Ford F-150 with the KINGROCK KR-2409 kit. It includes two suspension blocks, four U-bolts and mounting hardware to change suspension height while retaining the existing leaf springs.

The blocks feature welded construction with internal reinforcement and two locating pins per block. Their tapered profile ranges from 1-7/8 inches to 2 inches in height. The black finish on the blocks and U-bolts blends cleanly with the surrounding suspension components.

Features and Benefits

• Application: Ford F-150 2021–2026.

• Length: 13-1/4 inches.
• Width: 3-1/4 inches.

Kit Contents

• 2 rear suspension blocks.
• 4 U-bolts.
• 8 nuts.
• 8 flat washers.

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.

Block orientation: position the shorter, 1-7/8-inch end toward the front of the vehicle. The taller, 2-inch end must face the rear.

Verify proper locating pin engagement, full contact between the mounting surfaces, suitable shock length and adequate suspension clearances for the vehicle’s configuration.

Block Height and Actual Lift

The nominal 2-inch measurement refers to the block’s height. When replacing an existing block, the change in ride height depends on the difference between the two blocks. A 2-inch block therefore does not necessarily provide 2 inches of additional lift.
