The ProComp 3 Inch Rear Block Kit Ford F150 4WD is a practical, well-built rear lift solution for 2004 through 2020 F150 4WD owners who want to restore a useful rear rake for towing and hauling without cutting, welding, or making permanent changes to the factory truck. Built with OE-style construction, including factory-style bump-stop landings and locating pins, these 3-inch rear lift blocks are designed for F150 trucks equipped with rear leaf springs and factory blocks. At IMM Hawaii Parts, we carry this kit for F150 owners who want a reliable bolt-on rear block solution that fits cleanly and performs the way the factory suspension expects it to.
ProComp 3 Inch Rear Block Kit Ford F150 4WD With Factory Style Bump Stop Landings and Locating Pins
The factory-style construction on these blocks is what sets them apart from basic aftermarket alternatives. Each block includes integrated bump stop landings that ensure the bump stops contact the axle at the correct height after the blocks are installed, protecting the suspension from premature bottom-out at the wrong point in the travel range. The integrated locating pins keep each block precisely centered and positioned between the axle and the leaf spring pack through installation and through sustained driving, hauling, and towing loads without shifting or misaligning over time. For F150 owners who want rear blocks that behave like factory components, this ProComp kit from IMM Hawaii Parts delivers exactly that.
Restores Rear Rake for Better Towing and Hauling Performance
When a loaded F150 compresses under heavy cargo, a toolbox, or a camper shell, the rear suspension drops and the truck sits flat or nose high, creating an unstable and uncomfortable towing and hauling stance. The ProComp 3-inch rear blocks restore the slight forward rake that keeps the F150 sitting and handling properly under load by raising the rear of the truck back into the position the suspension was designed to work from. This improved rake makes a meaningful difference in towing stability, braking feel, and the general confidence of driving a heavily loaded F150 on the highway or through work site terrain.
Heavy Duty U-Bolts and All Required Hardware Included
Every component needed to complete the installation is included in this kit, including vehicle-specific heavy-duty U-bolts sized for the F150 4WD rear axle dimensions and all required fasteners and hardware. Using vehicle-specific U-bolts rather than generic hardware ensures the correct clamping force is applied across the rear axle during installation, keeping the blocks securely positioned through the sustained vibration and load stress that a working F150 regularly encounters. Customers appreciate that this kit arrives complete and ready to install without any additional hardware sourcing required.
Simple Bolt-On Installation With No Permanent Modifications
This rear block kit installs using a clean bolt-on process that requires no cutting of any factory F150 components and no permanent changes to the truck structure. The 3-inch blocks sit between the axle and the factory leaf spring pack at the factory mounting locations and are secured using the included heavy-duty U-bolts. The installation is straightforward, reversible, and leaves the factory rear suspension structure completely intact for owners who want to maintain the condition of their F150 while adding the practical rear lift they need for towing and hauling.
Important Notes Before Installing
The block height on this kit is 3 inches, but the actual lift gained after installation depends on the height of the factory rear block that is removed and replaced. This kit is designed specifically for 2004 through 2020 Ford F150 4WD trucks equipped with rear leaf springs and factory rear blocks. Always confirm your specific F150 build and rear suspension configuration before ordering.
