Superlift 73-87 Chevy K20/GMC K25 Pickup 4WD 4in Block Kit

Superlift has been around since 1975, building a reputation for suspension parts designed by truck and off-road enthusiasts who actually use their products. They know what it's like to spend time on the road and off, and they aim to make parts that perform well in both environments. This 4-inch rear block kit is designed to lift the rear of your 1973-1987 Chevy K20 or GMC K25 pickup, helping you achieve a more level stance or accommodate larger tires.

This kit includes two solid cast iron blocks, four U-bolts, and all the necessary nuts and washers for installation. The cast iron construction offers a strong foundation for the lift, and the included hardware means you have most of what you need to get the job done. It's a straightforward way to add a bit of height to the rear of your truck, commonly used when installing a lift kit or just to level out the vehicle's profile.
