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

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

What material are the suspension blocks made from?

The suspension blocks in this kit are constructed from ductile iron, which is a strong and durable material. They also feature fixed center pins for secure mounting.

What is the benefit of the e-coating on the U-bolts?

The e-coating applied to the U-bolts provides a layer of protection against corrosion. This helps to extend the life of the U-bolts, especially in environments where they might be exposed to moisture and road salt.

Product Details

Skyjacker is known for making suspension components that help you get the most out of your truck or SUV. This kit is designed to give your vehicle a lift in the rear using a combination of suspension blocks and U-bolts. It's a popular way to add a bit more clearance for larger tires or to level out the stance of your vehicle, and it fits a range of trucks like the Ford F-150, Jeep J20, and Toyota Pickup.

The U-bolts in this kit are e-coated to help them resist corrosion, which is important for parts exposed to the elements. The blocks themselves are made from ductile iron and come with fixed center pins. They're also tapered, which helps to correct the driveshaft angle after lifting the vehicle, reducing the chance of vibrations. You can choose blocks in various heights, from 1.25 inches up to 5 inches, to achieve the specific lift you're looking for.
