- EZ-Ride Front Springs: tuned for a smoother ride with low-friction performance; includes teflon pads to reduce noise and squeaking on uneven terrain.
- Rear Springs: 52-inch long leaf springs to enhance load support, stability, and ride quality with gear or cargo.
- Shocks: Not included in this kit; factory shocks must be replaced with extended shocks for proper installation.
- Tire Compatibility: supports up to 33" x 12.5" tires, giving you room for a more aggressive, off-road-ready look.
- Vehicle Fitment: designed for 1973–1987 Chevy Suburban K2500 4WD and 1973–1987 GMC Suburban/Truck K2500 4WD; not compatible with diesel engines; intended for 3/4-ton models.

- Hardware Included: complete mounting hardware kit with U-bolts, nuts, washers, and brackets for a straightforward install.
Benefits: This kit delivers a practical, durable lift that enhances ground clearance and tire options while maintaining ride quality on rugged classic pickups. The EZ-Ride springs reduce noise and improve ride feel, and the 52" rear springs improve load stability for camping gear, tools, or towing needs. Because shocks are not included, plan to install extended shocks to maximize travel and control. If you’re working with a 1973–1987 3/4-ton 4WD Chevy Suburban or GMC truck, this Tuff Country lift kit provides a value-focused upgrade built to last, backed by a loyal heritage of suspension expertise.
| Important Installation Note | Factory front & rear shocks must be replaced with new extended shocks to install this lift kit properly. Please choose shocks & boots in the "Options" fields above if you have not already purchased extended shocks. |
