Product Details
Description
The Tuff Country 13730KN 3" Lift Kit with EZ-Ride Front Springs, Rear Lift Blocks, and SX8000 Shocks is a complete suspension upgrade designed for Chevy and GMC 4x4 trucks from the late 1980s to early 1990s. It provides a practical 3-inch lift to improve ground clearance, support larger tires, and enhance overall ride quality.
- Lift Height: 3-inch overall lift to elevate the stance and improve off-road capability.
- EZ-Ride Front Springs: Advanced EZ-Ride leaf springs that enhance ride quality and load handling when lifted.
- Rear Lift Blocks: Precisely designed blocks to maintain proper axle alignment and factory-like geometry.
- SX8000 Shocks Included: Front and rear shocks tailored to this kit for improved damping and control on and off-road.
- Teflon Noise Pads: Integrated pads to minimize noise and squeaking for a quieter ride.
- Tire Compatibility: Enables use of 33" x 12.5" tires for enhanced traction and a bolder look.
- Durable Construction: Engineered for rugged reliability with components built to withstand off-road use.
- Fitment Notes: Designed for 1988–1991 Chevy Blazer 4WD, Suburban K1500 4WD, and GMC Jimmy 4WD (gas engines only; diesel engines will not fit).
- Installation Time: Typical installation ranges from 4–6 hours with standard workshop tools.
- Warranty: Backed by Tuff Country’s limited lifetime warranty on the leaf springs and the overall kit.
This kit helps you tackle rough terrain with confidence: added ground clearance, room for bigger tires, and a smoother, more controlled ride thanks to EZ-Ride springs and SX8000 damping. The rear blocks preserve proper alignment, so you can carry gear or tow with steadier handling. Built on decades of suspension engineering, this Tuff Country kit offers a focused solution for classic GM 4x4 trucks, delivering real-world benefits without compromising stability or everyday drivability.
