McGaughy's 2.8" Lift Block Kit with U-Bolts – 2020-2025 Silverado / Sierra 2500HD & 3500HD 2WD & 4WD

Pair your McGaughy's 4" lift kit with these 2.8" Rear Lift Blocks to bring back the factory rake on your Chevrolet Silverado or GMC Sierra 2500HD/3500HD. Standing a full inch taller than the blocks included with the 4" kit, these precision-engineered blocks add extra rear height. Built from high-quality materials, they install using the u-bolts already supplied with your McGaughy's lift kit, making this one of the simplest upgrades you can bolt on.

Key Features:

• Designed exclusively for use with McGaughy's 4" lift kits on Silverado and Sierra 2500HD/3500 trucks.
• Adds 1 inch of rear height over the standard 4" kit blocks to restore factory rake.
• Maintains factory suspension geometry for a smooth, controlled ride.
• Constructed from high-quality materials for superior strength and long-lasting durability.
• Fits all configurations including AT4X and ZR2 models.
• Simple bolt-on installation reusing the u-bolts from your McGaughy's lift kit.

Kit Includes:

• (2) Rear Lift Blocks
