Product Details
Description
The Tuff Country 14067KN 4" Uni-Ball Lift Kit is a complete suspension upgrade designed for 2007–2018 Chevy Silverado 1500 and GMC Sierra 1500 2WD models. It provides a 4" front lift and a 2" rear lift, enabling larger tires while preserving a near-factory ride and confident on-road handling.
- Lift Height: 4" front / 2" rear to maximize ground clearance and tire compatibility
- Core System: Uni-ball Upper Control Arm Drop / Strut Spacer Kit for improved articulation and smoother travel
- Shocks Included: SX8000 shocks paired with the kit for balanced damping and stable ride quality
- Rear Suspension: Rear blocks and U-bolts to maintain proper axle positioning
- Wheel Fitment: Supports up to 33" x 12.5" tires; requires rims with 4.5" backspacing
- Installation Notes: No drilling required; designed for vehicles with OE one-piece cast steel upper arms
- Warranty: Limited lifetime warranty provides long-term assurance on the lift system
- Made in the USA: Proudly manufactured in the United States with U.S. sourcing
- Vehicle Scope: Custom-fit for 2007–2018 Chevy Silverado 1500 and 2007–2018 GMC Sierra 1500 2WD
The 4" Uni-Ball Lift enhances capability without radically changing the vehicle’s core characteristics. With this kit you gain true off-road potential—clearance for uneven terrain, room for larger wheel and tire packages, and improved front-end articulation thanks to the Uni-ball design. The SX8000 shocks work alongside the taller front end to maintain stability during rough terrain, while rear blocks preserve axle geometry for even loading and predictable handling. Built with durability in mind, the kit aims for a balanced, near factory feel during daily driving, so your truck remains comfortable when you’re not charging into trails. For best results, ensure your wheels have 4.5" backspacing and note that Magnetic Ride Control or air suspension-equipped models are not compatible with this lift.
