Superlift 99-10 Chevy Silv/GMC Sierra 1500/2500 4WD 2.5in Block Kit

This 2.5-inch rear block kit from Superlift uses solid cast iron blocks, a strong material choice that holds up well under load. It's designed to give your 1999-2010 Chevy Silverado or GMC Sierra 1500 or 2500 4WD truck a 2.5-inch lift in the rear, helping to level out the stance if you've added a lift to the front or if you haul heavy loads.

Included in the kit are two cast iron blocks, four U-bolts, and all the necessary nuts and washers for installation. This means you get everything you need to get the job done without having to hunt for extra parts. Superlift has been around since 1975, and they focus on making parts that perform well both on and off-road, with a commitment to customer satisfaction.
