Product Details
Description
The Tuff Country 12721KN 2" Lift Kit with EZ-Ride front springs, 52" rear springs, and SX8000 shocks is a practical, value-driven upgrade for classic GM 3/4-ton 4WD trucks and Suburbans. Designed for gasoline-engine models from 1973–1987, it delivers a clean two-inch lift that enhances clearance, tire options, and overall stance.
- Lift Height: 2 inches of front and rear lift to improve ground clearance and accommodate larger tires without changing ride geometry.
- EZ-Ride Front Springs: Advanced leaf springs with Teflon pads to reduce noise and squeaks while improving ride quality and articulation.
- 52" Rear Springs: Longer rear leaves engineered for better load handling and a steadier, more stable ride under load.
- SX8000 Shocks: Included shocks provide controlled damping for smoother on-road feel and confident off-road performance.
- Shocks Included: Front and rear SX8000 shocks are part of the kit, ensuring you have the components needed for a complete upgrade.
- Installation Note: Factory front and rear shocks must be replaced with extended shocks to install the lift kit properly.
- Vehicle Fitment: Specifically designed for 1973–1987 Chevy Suburban K2500 4WD, Chevy Truck K2500 4WD, GMC Suburban K2500 4WD, and GMC Truck K2500 4WD (gasoline engines only; diesels not supported).
- Warranty: Limited lifetime warranty on the leaf springs for long-term peace of mind.
- Recommended Tire Size: Optimized for up to 32" x 10.5" tires to balance height, handling, and gearing on older GM platforms.
- Install Time: Typical installation ranges from 4 to 6 hours with proper tools and a methodical setup.
With this lift kit, you’ll gain a more commanding road presence, expanded tire compatibility, and improved off-road capability without sacrificing essential stability. The EZ-Ride springs reduce road noise and improve ride quality, while the longer rear springs enhance load support during gear-hauling or towing. The SX8000 shocks deliver predictable damping for both daytime highway driving and rugged trail use, helping you maintain control across varied terrains. Supported by Tuff Country’s decades of suspension expertise and a limited lifetime warranty on the springs, this kit offers a reliable, value-focused path to a capable, comfortable lifted ride.
| Important Installation Note | Factory front & rear shocks must be replaced with new extended shocks to install this lift kit properly. Please choose shocks & boots in the "Options" fields above if you have not already purchased extended shocks. |
