What is the purpose of the tapered blocks?

The tapered blocks are designed to correct the pinion angle of your driveshaft after lifting the rear of your vehicle. This helps to prevent driveline vibrations and ensures a smoother ride.

What material are the U-bolts made from?

The U-bolts included in this kit are e-coated for corrosion resistance. This coating helps protect them from rust and environmental damage, extending their lifespan.

What is the difference between ductile iron and regular cast iron?

Ductile iron is a type of cast iron that has been treated to improve its strength and ductility. It's a well-built material that can withstand more stress and impact than standard cast iron, making it suitable for suspension components.

Product Details

If you're looking to add a little lift to the rear of your truck for a more aggressive stance or to fit slightly larger tires, this Skyjacker Suspension Block and U-Bolt Kit is a solid option. This kit is designed to work on a wide range of GM trucks and SUVs from the late 80s through the late 90s, including popular models like the 1988-1999 GMC K1500 and Chevrolet K1500 Suburban.

The blocks themselves are made from ductile iron, which is a strong material that can handle the stresses of lifting your vehicle. They feature fixed center pins and are tapered to help correct the driveshaft angle, which can help prevent driveline vibrations after the lift. The included U-bolts are e-coated to resist corrosion, keeping them looking good and functioning properly for a long time, even in rough conditions. This kit offers lift heights from 1.25 to 5 inches, so you can choose the amount of lift that best suits your needs.
