Product Details
Description
Raise the rear of your GM SUV or pickup with confidence using the Tuff Country 97003 Block & U-Bolt Kit. Engineered for rear-axle installations on Chevy Blazer, Suburban K1500, and GMC variants, it delivers a reliable 1.5-inch lift while preserving a comfortable, factory-like ride.
- Rear Lift Height: Adds 1.5 inches of rear height to level the stance when lightly loaded or towing.
- Block Construction: Heavy-duty non-tapered lift blocks crafted for durability; kits may include cast blocks (or aluminum blocks in some configurations).
- U-Bolt Hardware: Extended, zinc-plated rear u-bolts designed specifically for Chevy Blazer applications, paired with appropriate nuts and washers for a secure fit.
- U-Bolt Dimensions: 5/8" diameter x 3" wide x 11 3/4" long, round style to match the original mounting geometry.
- Shocks Compatibility: For lifts around 2" or higher, factory shocks are generally not long enough—extended-length shocks are recommended to maintain proper damping and travel.
- Installation: Simple bolt-on installation that inserts the lift blocks between the factory rear leaf springs and axle; designed for rear-axle use only, not suitable for front axles.
- Finish: Zinc-plated hardware and corrosion-resistant components to endure road grime and weather exposure.
- Vehicle Fitment: Specifically tuned for 1973–1991 Chevy Blazer 4WD, 1973–1991 GMC Blazer 4WD, 1973–1991 Chevy Suburban K1500 4WD, and 1973–1987 Chevy Truck / 1973–1987 GMC Truck K1500 4WD 1/2 ton models.
With the 97003 kit, you gain a controlled rear lift that improves stance and balance when carrying cargo or towing, while keeping ride comfort at the forefront. The combination of solid lift blocks and zinc-coated u-bolts delivers dependable performance in varied conditions, and the bolt-on design makes installation accessible for DIY enthusiasts. If you’re planning a taller lift (2" or more), plan on upgrading to extended-length shocks to maintain optimal damping and suspension travel. This kit is a practical, long-lasting upgrade for classic GM SUVs and trucks seeking a more level, capable rear end.
