16722KN BOX 4 OF 4

The Tuff Country 14722KN 4" Lift Kit is a purpose-built suspension upgrade for heavy-duty GM 3/4-ton 4x4s from the 1970s and 1980s. It combines reliable EZ-Ride front springs, long rear springs, a steering arm, and SX8000 shocks to deliver a confident, balanced lift that supports larger tires and improved off-road capability. This lift kit is built for enthusiasts who want a durable, straightforward upgrade to improve ground clearance, tire fitment, and off-road capability on classic GM 4x4s. EZ-Ride springs minimize ride disturbances and noise, while SX8000 shocks provide steady dampening to keep the ride predictable on rocky trails. With a complete install kit and clear fitment guidelines, you can confidently restore or upgrade your 3/4-ton GM truck or Suburban to handle tougher terrain and bigger tires—while preserving reliability and long-term performance with a trusted brand.
