ICON Vehicle Dynamics 1 Inch Cast Iron Lift Block Kit

The ICON Vehicle Dynamics 1" Cast Iron Lift Block Kit is a pair of cast iron rear lift blocks designed to raise a truck's rear ride height by one inch. The kit is a straightforward, cost-effective alternative to a full suspension replacement when a modest rear lift is the goal. U-bolts are sold separately.

Simple Rear Lift, Solid Construction

Cast iron construction gives these lift blocks the rigidity needed to sit between the axle and the leaf spring pack without flex or deformation under load. A one-inch block is one of the most common increments for correcting rear sag, leveling a loaded truck bed, or matching a front lift already in place. A block kit accomplishes that without replacing springs or other suspension hardware.

What Is and Isn't Included

The kit ships with two cast iron lift blocks, one per side. U-bolts, which must be replaced any time a lift block is installed, are not included and must be ordered separately. Using the correct-length U-bolts for the specific vehicle and axle is required for a safe installation.

Features

• One-inch rear lift: raises rear ride height by 1" using a block between the axle and leaf spring pack
• Cast iron construction: rigid, high-quality cast iron blocks sold as a pair
• U-bolts sold separately: compatible U-bolts must be sourced and replaced at installation

Specifications

Who This Is For and Isn't

This kit suits truck owners running a leaf-spring rear suspension who need a simple one-inch rear lift to level the vehicle, correct mild rear sag under typical load, or complement a front lift already installed.

This kit does not include U-bolts; a complete installation requires separately purchased U-bolts sized for the specific vehicle and axle. Vehicle fitment has not been confirmed in the available product data. Verify compatibility before ordering.

Common Questions

How much does this kit raise the rear of the truck?

The ICON 1" Cast Iron Lift Block Kit raises the rear ride height by one inch. The blocks are installed between the axle and the leaf spring pack on each side of the rear axle.

Do U-bolts come with this kit?

U-bolts are not included with the ICON 1" Lift Block Kit and must be purchased separately. Replacing U-bolts is required any time lift blocks are installed, so the correct size for the specific vehicle and axle must be sourced before installation.

What material are the lift blocks made from?

The lift blocks in this kit are cast iron. Cast iron provides the rigidity needed to support the axle and spring pack without flex under normal truck loads.
