What is the purpose of the tapered blocks in this kit?

The blocks are tapered to help correct the driveshaft's pinion angle after lifting the rear of your vehicle. This is important for preventing driveline vibrations and ensuring smooth operation.

What does the e-coating on the U-bolts do?

The e-coating is applied to the U-bolts to provide resistance against corrosion. This helps to protect the metal from rust and degradation, especially in wet or harsh environments, extending their lifespan.

What else might I need to install this kit?

While this kit includes the blocks and U-bolts, you may need additional tools for installation such as wrenches, a torque wrench, and potentially a jack and jack stands. It's always recommended to consult the manufacturer's installation instructions for a complete list of tools and procedures.

Product Details

If you're looking to lift the rear of your truck or SUV for a more aggressive stance or to fit larger tires, this Skyjacker suspension block and U-bolt kit is a solid option. This kit is designed to add 4 inches of lift to the rear suspension, helping to level out your vehicle or prepare it for off-road adventures. It's a popular choice for many Ford F-150, Jeep Cherokee, and Jeep J10 owners from the 1970s and 1980s.

The kit includes ductile iron blocks that feature fixed center pins for a secure installation. These blocks are tapered, which is a smart design choice because it helps to correct the driveshaft's pinion angle. This correction is important for preventing those annoying driveline vibrations that can occur after lifting a vehicle. The included U-bolts are e-coated to resist corrosion, ensuring they hold up well over time, even in harsh conditions. This attention to material and design means you're getting a well-built kit that addresses common issues associated with lifting.
