Superlift 73-87 Chevy K5 K10/GMC K15 4in Block Kit

If you're looking to level out the stance of your classic Chevy or GMC truck, this 4-inch rear block kit from Superlift is a solid option. It's designed to lift the rear of your vehicle, helping to correct the common nose-down look that can happen after installing a front lift or just from age. This kit fits a wide range of 1973-1991 GM 1/2 ton pickups, Suburbans, Jimmys, and Blazers, including popular models like the K5 Blazer and K10 Pickup.

The kit includes two solid cast iron blocks, which are known for their strength and durability. You'll also get four heavy-duty U-bolts along with all the necessary nuts and washers to get the job done. Installing these blocks is a straightforward way to gain a bit of rear height without altering your existing leaf spring setup. It's a practical modification for trucks that see a mix of on-road driving and occasional off-road use.
