Skyjacker Suspension Block and U-Bolt Kit 1999-2006 GMC Sierra 1500 4 Wheel Drive

When you're looking to lift the rear of your 1999-2018 Chevrolet Silverado 1500 or 1999-2018 GMC Sierra 1500 4WD, this Skyjacker Suspension Block and U-Bolt Kit is what you get. Inside the box, you'll find ductile iron blocks with fixed center pins, designed to give you a lift ranging from 1.25 to 5 inches. These blocks are tapered, which helps to correct your pinion angle and prevent those annoying driveline vibrations that can come with lifting a vehicle.

Along with the blocks, the kit includes U-bolts that have been e-coated to resist corrosion, keeping them strong and functional for longer. Skyjacker offers these U-bolts in various shapes and sizes to ensure a proper fit for your specific application. This combination of well-built blocks and durable U-bolts is a popular way to achieve rear lift on these trucks.
