SuspensionMAXX Heavy Duty Block and U-Bolt Rear Leaf Spring Leveling Kits are the perfect solution for lifting or leveling the rear of trucks or SUV’s carrying heavy loads including campers.  Such loads can cause rear suspension to compress and sag - thereby reducing rear ride height. Our Block and U-Bolt Kits simply fit between rear leaf springs and axle to compensate for suspension compression and restore rear ride height.

SuspensionMAXX Heavy Duty Block and U-Bolt Rear Leaf Spring Leveling Kits utilize premium quality high strength components including CNC drilled and located solid steel blocks, heavy-duty Grade 8 U-Bolts, tall nuts and extra thick washers. Installation can be done in about 1.5 hours and is supported by SuspensionMAXX Technical Support Program.
