KSP 3in Silverado Rear Lift Block Kit - 3in Rear Lift for 1999-2024

Our review of the KSP 3in Silverado Rear Lift Block Kit finds it best suited for owners who need a straightforward, dependable 3in rear lift for Silverado and Sierra 1500 trucks from 1999 through 2024. The single biggest reason to buy is the combination of a cross gusset plate locked lift block and black powder coated finish that delivers stronger support and improved rust resistance compared with basic blocks. Installation is simple for anyone familiar with leaf spring work, and the kit includes longer 10.9 grade u-bolts so installers do not have to hunt for parts.

Key Features

• Fitment: Direct-fit design for 1999-2024 Chevy Silverado 1500 and 1999-2024 G-M-C Sierra 1500 2WD and 4WD models, reducing compatibility guesswork.
• Black Powder Coated: The block surfaces are powder coated to resist rust and keep the lift looking clean under the truck for longer service life.
• Cross Gusset Plate Locked: The gusset plate locked design gives stronger structural support to the rear block assembly compared with unbraced blocks.
• 10.9 Grade U-Bolts: Longer 10.9 grade u-bolts with 9/16 thread pitch provide high strength and flexibility for tuners, and can be cut if too long.
• Complete Hardware: The kit ships as a two-piece rear lift block with four extended square leaf spring u-bolts to keep the installation self-contained.

Who It's For

This kit is aimed at Silverado and Sierra 1500 owners who want a modest 3in rear lift for improved stance, clearance, or to level a truck running heavier front lift or accessories. It is a good choice for do-it-yourself mechanics and professional installers who need parts that fit 1999-2024 2WD or 4WD trucks without aftermarket modification.

Drivers who need a larger lift, complex suspension re-geometry, or who prefer a complete lift kit with shocks and block-matched hardware should look elsewhere, since this product focuses on the rear lift block and extended u-bolts rather than a full suspension overhaul.
