Product Details
Description
Tuff Country 97010 Block & U-Bolt Kit delivers a clean 4-inch rear lift for Chevy/GMC 3/4-ton 4WD trucks with a focus on reliability and a factory-like ride. Designed for rear axles only, this bolt-on kit elevates the rear for improved stance, capability, and clearance without compromising handling.
- Lift Height: 4" rear lift to noticeably improve ground clearance and load stance on 3/4-ton Chevy/GMC 4WD models.
- Block Material: Heavy-duty cast iron blocks (tapered design) engineered to minimize driveline vibration and maintain smooth operation.
- Block Dimensions: 4" (H) x 2 1/2" (W) x 4 3/4" (L) for a precise fit with factory springs and axles.
- U-Bolt Hardware: Extended zinc-plated rear u-bolts designed specifically for Chevy trucks, plus accompanying nuts and washers for secure mounting.
- Block Design: Tapered blocks reduce driveline stresses and help preserve alignment during travel and acceleration.
- Compatibility: Fits rear axles on 1973–1991 Chevy Suburban K2500 4WD, 1973–1987 Chevy Truck K2500 4WD, 1973–1991 GMC Suburban 4WD 3/4 Ton, and 1973–1987 GMC Truck K2500 4WD.
- Installation Notes: Simple bolt-on installation by inserting the blocks between the factory rear leaf springs and axle. Factory shocks may need to be replaced with extended-length shocks when using blocks 2" tall or taller.
- Block Options: Kits may include CAST BLOCKS or ALUMINUM BLOCKS depending on the specific package.
This kit is built to withstand demanding use, from daily driving to towing and payload work. The tapered block design, zinc-plated hardware, and targeted fit for Chevy/GMC 3/4-ton 4WD trucks ensure a durable solution that delivers increased rear height, improved stance, and reliable performance over time.
