Adds Rear Ride Height for Towing, Hauling, or to Compensate for a Leveling Kit

Whether you need to get extra rear ride height for preventing squat when towing heavy or to help you win back a good amount of rake after installing a front leveling kit, adding a larger rear block to your 2021-2022 F150 may be a good bet. The Auto Spring 3" Rear Block Kit for 2021-2022 F150s add around 1.75" of rear ride height to 4WD F150s. The increase in ride height on the 4WD F150s is more than enough to help keep your truck level when you're towing and hauling heavy or to give you back rake after adding a leveling kit so you don't end up sitting nose-high when towing or hauling. The Auto Spring 2021-2022 F150 3" Rear Block Kit features a durable construction and drops right into place of your F150's factory block without modifications, making them an easy, hassle-free upgrade for your awesome F150 build.

OEM-Style Cast Steel Lift Blocks with Black Polyurethane Finish and Grade 8 U-Bolts

The Auto Spring Rear Blocks are made to be incredibly strong all while easily dropping onto your truck. Each of the blocks included in this kit are made out of OEM manufacturer-style cast steel that's far more durable than typical cast iron or billet aluminum rear blocks. The blocks come standard with a black polyurethane finish that protects the blocks from corrosion while letting them blend in with your F150's undercarriage. The block kit comes standard with grade 8 U-bolts and nuts that keep the blocks locked to your F150's axle no matter how hard you're ripping your 2021-2022 F150 around. The Auto Spring rear blocks are easy, drop-in replacements for your F150's stock rear blocks. These blocks are made right here in the USA and come backed by a limited lifetime warranty.
