- Warranty and support: backed by Tuff Country’s limited lifetime warranty on leaf springs and the kit’s overall lifetime assurance for long-term peace of mind.
- Installation: typically 4–6 hours of install time, depending on your shop or garage experience and vehicle condition.
- Compatibility notes: specifically for 1988–1991 Suburban K2500 4WD models; will not fit diesel engine variants and is intended for 3/4-ton configurations.
This kit translates into real-world benefits: a confident, capable ride on rough roads or light trails, improved tire clearance for a more aggressive look, and a suspension system tuned to minimize ride harshness while maintaining handling precision. The EZ-Ride springs work with SX8000 shocks to deliver a balanced combination of comfort and control, making daily driving and weekend adventures more enjoyable. With a trusted brand heritage and the protection of a lifetime warranty, this 3-inch lift kit is a strategic upgrade for serious Suburban enthusiasts seeking lasting value.
