U-Bolts. Block and U-Bolt kits can also be used to level vehicles that carry heavy loads. SuspensionMAXX Heavy Duty Block and U-Bolt Kits are made with quality alloy metals for high strength and long life – they won’t crack or compress.  

SuspensionMAXX provides all hardware needed and components are quickly installed using job specific tools. Installation involves no major alterations to the vehicle and the truck or SUV can easily be put back to stock specifications. Made in America and covered under the MAXX Structural Lifetime Warranty.

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.

1.5" lift

No, this is not necessary on blocks less than 3” in height.  No change in pinion angle is required for 1-2.5” of lift.

Suspension MAXX block and U-bolt kits use high-quality blocks from SOLID STEEL, unlike the cheaply made hollow cast import lift blocks. Each of our blocks is precision cut and CNC machined.  We also use All- American made steel U-bolts, Tall Nuts, and Heavy Duty washers.

Factory shocks have 8-12” of shock travel and can work well with 1” and 1.5” of lift on most trucks.  2” of lift is the maximum height of lift we recommend; it depends on the application as some vehicles like F150 trucks have extremely long shocks from the factory.  Shock extensions or longer shocks will be needed for sharp drop-offs, like speed bumps, for example.
