- Teflon Pads: Reduce noise and squeaks for a quieter daily drive and trail use.
- Tire Compatibility: Supports up to 33" x 12.5" tires when paired with appropriate wheels, expanding off-road and clearance options.
- Installation Time: Average 4–6 hours for a thorough, safe upgrade (professional installation recommended).
- Vehicle Fitment: 1973–1987 Chevy Suburban K2500 4WD and 1973–1987 GMC Suburban/Truck K2500 4WD; diesel engines are not supported.
- Warranty: Limited lifetime warranty on leaf springs for long-term confidence.
This kit combines durable leaf springs, rear blocks, and precision-fit components to deliver a reliable, controlled lift that enhances ground clearance, approach/departure angles, and overall stance. It’s ideal for weekend trail explorers, hunters, campers, or anyone restoring a rugged look to a classic 3/4-ton 4WD. With Tuff Country’s 25+ years of suspension expertise behind it, you gain a proven solution that prioritizes performance, durability, and value. Note that shocks are sold separately, and this kit is tailored for the specified 4WD models—not suitable for diesel variants. If you’re upgrading your Suburban for tougher terrain or heavier loads, this 3" lift provides an accessible, solid foundation to grow with your setup over time.
