Tuff Country 12000KN 2" Leveling Kit (Upper Mount Billet Aluminum Spacers) with SX8000 Shocks
Product Details
Description
Raise the front of your GM truck or SUV with the Tuff Country 2-Inch Front Leveling Kit featuring SX8000 shocks. This bolt-on solution is designed for models with front coilovers, delivering a balanced stance, improved handling, and room for larger tires without sacrificing ride quality.
- 2" Front Lift: Achieves a level stance by lifting the front end while keeping the rear untouched for a classic, unified look.
- Includes SX8000 Shocks: Upgraded front shocks are part of the kit, providing improved damping and control.
- Billet Aluminum Spacers: High-strength upper-mount spacers designed for durability and precise alignment.
- No Drilling Required: Simple bolt-on installation with common tools; no drilling or cutting needed.
- No Strut Disassembly: Reuses factory components for a straightforward, efficient install.
- Maintains Factory Ride: Engineered to preserve OEM feel while adding height and improved stability during handling.
- Lifetime Warranty: Confident protection from Tuff Country, a trusted name with decades of suspension expertise.
- Made in the USA: Proudly manufactured in the United States for quality you can trust.
- Vehicle Fitment: Suitable for 2007–2025 GM trucks and SUVs with front coilovers (including Silverado 1500, Suburban 1500, Tahoe, Sierra 1500, and Yukon/Yukon XL). Not compatible with Trail Boss/AT4, Magnetic Ride Control, or Air Suspension.
- Wheel/Tire Guidance: Supports up to 32x10.50 tires with aftermarket rims. A positive 30 offset is required for proper clearance; lower offsets may require trimming. Factory rims typically require no trimming.
With this leveling kit, you’ll reduce the nose-down look and gain clearer tire clearance, opening the door to larger, more capable tires while preserving a smooth, comfortable ride. The kit’s design minimizes suspension disruption, so daily driving stays composed, even on imperfect pavement. For enthusiasts who want a more aggressive stance without sacrificing ride quality, this is a reliable, straightforward upgrade backed by a lifetime warranty and made in the USA.
