dynofit 3-Inch Rear Lift Blocks for Silverado/Sierra 1500 (2007–2024) — CNC Steel, Powder-Coated

dynofit 3 Inch Rear Lift Blocks are a CNC-machined steel leveling kit designed to add 3 inches of rear lift to 2007–2024 Chevy Silverado 1500 and GMC Sierra 1500 pickups, supplied with extended U-bolts and hardware for a secure fit.

If you need to correct rake, improve ground clearance, or fit larger tires on a Silverado or Sierra, this kit gives a simple, bolt-on solution without major suspension surgery. The lift blocks are precision-machined from steel, powder-coated for corrosion resistance, and paired with longer-grade bolts and thicker washers to handle the load and maintain contact with the leaf springs. The package includes two lift blocks and four extended U-bolts sized to replace factory hardware for square leaf spring axles.

How will these blocks affect my truck’s ride and clearance?

Adding a 3-inch rear block raises the rear axle, increasing tire clearance and reducing front-to-rear rake. That extra lift can help accommodate taller tires or level the truck when towing or hauling moderate loads. While lift blocks are a durable and economical option, they change rear suspension geometry and may slightly alter handling and ride firmness.

• 3-inch nominal rear lift for added clearance and a level stance
• Increased tire fitment room for larger diameter tires
• Simple installation keeps stock springs intact

What materials and hardware come with the kit?

The blocks are CNC-machined steel with a black powder-coat finish to resist rust and wear. Hardware includes four extended U-bolts manufactured from high-strength steel with 9/16" thread pitch and heavy washers to spread load. Bolt grades meet 10.9–12.9 specifications for improved tensile strength.

• Two CNC-machined steel lift blocks, black powder-coated
• Four extended U-bolts (colors shipped randomly: black or yellow)
• High-grade bolts and thicker washers for reliable clamping

Is installation difficult and what should I expect during fitment?

Installation is straightforward for anyone comfortable with basic axle and suspension work; you’ll need to support the axle, remove existing U-bolts, insert the block between axle and leaf spring perch, and torque new U-bolts to spec. No cutting or spring replacement is required, but proper torqueing and alignment checks after installation are recommended.

• Direct bolt-on replacement for square leaf spring axles on specified models
• Requires jack stands and torque wrench; moderate mechanical experience advised
• After installation, check wheel alignment and torque after initial road miles

Who is this for: This kit is intended for owners of 2007–2024 Chevy Silverado 1500 or GMC Sierra 1500 trucks, 2WD or 4WD, who want a cost-effective, reversible way to raise the rear 3 inches for better clearance, to level the truck, or to make room for larger tires without changing leaf springs. It suits do-it-yourself mechanics and professional installers looking for CNC-machined durability and corrosion-resistant finish, as long as users accept the typical handling trade-offs of rear lift blocks.
