Product Details
Description
Upgrade your GM 4x4 with the Tuff Country 14712KN 4" Lift Kit—a comprehensive suspension system built for 1973–1987 Chevy and GMC 4WD models (Blazer, Suburban, Jimmy, and Truck). It delivers a reliable 4-inch lift with steel performance components, making room for larger tires and tougher terrain without compromising stability.
- Lift height: 4 inches of overall suspension lift to increase ground clearance and off-road capability.
- Front springs: Heavy-duty front leaf springs designed for big-block engines and snow plows, providing durable, dependable support.
- Rear suspension: Rear blocks paired with appropriate hardware to maintain axle geometry and load handling after the lift.
- Steering arm: Sturdy steering arm engineered to preserve steering feel and alignment post-lift.
- Shocks included: SX8000 shocks included for improved damping and a balanced ride on and off the pavement.
- Noise reduction: Teflon pads used to minimize noise and squeaking for a smoother, quieter ride.
- Tire compatibility: Ready for up to 33" x 12.5" tires, enhancing traction and stance when you’re off the beaten path.
- Warranty: Limited lifetime warranty on leaf springs, providing long-term confidence in your investment.
- Install time: Typical installation ranges from 4–6 hours with proper tools and know-how.
- Fitment notes: Designed for 1973–1987 GM 4WD models; will not fit diesel engine configurations; suitable for 1/2-ton models.
With this kit, you gain meaningful ground clearance for rough trails and obstacles, a more capable stance, and improved tire options without sacrificing ride quality. The SX8000 shocks deliver controlled handling across urban roads and rugged trails, while the heavy-duty front springs support heavier engines and practical duties like plowing. The teflon pads minimize annoying squeaks, and the leaf-spring warranty reinforces your long-term reliability. This is a purpose-built upgrade from a brand with decades of suspension expertise, designed to help you get more from your GM 4x4 both on and off the road.
