Tuff Country 79064 1" Lift Blocks 2.5" Width Non-Tapered - Pair
Product Details
Description
Tuff Country 79064 lift blocks provide a robust, cast-iron solution to elevate the rear of heavy-duty trucks that use leaf-spring suspensions. Designed for GMC Sierra 2500HD and Chevy Silverado 2500HD 4WD models from 2001–2010, this pair adds a reliable 1 inch of lift for improved stance under load.
- Block dimensions: 5" wide by 1" tall per block, non-tapered design for straightforward installation and even load distribution.
- Material: Cast iron construction built to endure heavy-duty use and resist wear under load.
- Design: Non-tapered blocks engineered to sit between the leaf springs and rear axle for consistent elevation.
- Vehicle compatibility: Fits 2001–2010 GMC Sierra 2500HD 4WD and 2001–2010 Chevy Silverado 2500HD 4WD.
- Set configuration: Comes as a pair, providing balanced lift on both sides of the rear suspension.
These lift blocks help restore a level stance when the vehicle carries heavier payloads or pulls trailers, reducing rear sag and improving overall balance between front and rear heights. The combination of durable cast iron and a precise, non-tapered profile ensures stable ride characteristics and long-term durability on demanding jobs or weekend adventures.
