Superlift 73-87 Chevy K20/GMC K25 Pickup 4WD 5in Block Kit

If you're looking to give your 1973-1987 Chevy K20 or GMC K25 4WD pickup a bit more rear-end height, this 5-inch block kit from Superlift is a solid option. This kit is designed to work with a range of GM 3/4 ton trucks and Suburbans from the mid-70s through the late-80s, offering a straightforward way to lift the back of your vehicle.

The kit includes two durable cast iron blocks that fit between your leaf springs and the rear axle. You'll also get all four necessary U-bolts, along with all the nuts and washers needed to get everything securely bolted down. This setup is a popular choice for those wanting to level out their truck's stance or make room for larger tires without altering the existing suspension geometry too drastically.

Superlift has been in the suspension game since 1975, and they stand behind their products with a Limited Lifetime Warranty, so you can feel confident about this addition to your truck.
