Product Details
Description
Elevate your heavy-duty Chevy or GMC with the Tuff Country 12921KN 2" Lift Kit — a simple, bolt-on solution designed for 3/4-ton and 1-ton 4WD trucks and Suburban models. This kit adds a practical 2" of front and rear lift with included SX8000 shocks, delivering improved clearance without compromising the vehicle’s essential rake.
- Lift Height: Adds 2" of front and 2" of rear lift for a balanced, level stance while preserving the factory rake (rear slightly higher than the front).
- Shocks Included: SX8000 shocks paired with the kit to enhance damping for on-road comfort and light off-road capability.
- Rear Suspension Enhancement: Rear add-a-leafs provide additional lift and load support for better capacity and stability.
- Torsion Bars & Keys: Includes torsion bars and keys that are designed to install with stock suspension only; not compatible with other lift kits (will void warranty if mixed).
- Installation Type: Simple bolt-on installation that minimizes downtime and avoids the need to crank torsion bars.
- Made in the USA: Proudly manufactured in the United States, emphasizing quality and durability.
- Warranty: Backed by a lifetime warranty, reflecting Tuff Country’s commitment to long-lasting suspension solutions.
- Tire Compatibility: Supports up to 32" x 11.5" tires, increasing traction and versatility for tougher terrains.
- Vehicle Fitment: Specifically designed for 1992–1998 Chevy Suburban 2500 4WD without Autotrac; 1988–1998 Chevy Truck K2500/K3500 4WD 8-Lug without Autotrac; 1992–1998 GMC Suburban 2500 4WD without Autotrac; 1988–1998 GMC Truck K2500/K3500 4WD without Autotrac.
The 12921KN kit leverages Tuff Country’s 35+ years of suspension expertise to deliver a trustworthy upgrade that stays true to real-world use. Expect improved ground clearance for rough roads and modest trails, more tire clearance for larger diameters, and a coherent ride between front and rear. The included SX8000 shocks help maintain control on highway speeds and off-road excursions, while the rear add-a-leafs keep load handling consistent with the lifted stance. This kit is an ideal choice for drivers who want a straightforward, durable lift that respects the vehicle’s original design and towing capability.
