Upgrade your 3/4-ton Chevy or GMC 4WD with the Tuff Country 13720K EZ-Ride 3" Lift Kit. Designed for 1973–1987 Chevy Suburban K2500, Chevy Truck K2500, GMC Suburban K2500, and GMC Truck K2500 4WD models, this kit provides a reliable 3" front and 3" rear lift that enhances stance and capability without breaking the bank.

  • Lift Height: 3" front and 3" rear to achieve a balanced, lifted stance across the axle line.
  • EZ-Ride Leaf Springs: Engineered to improve ride quality while adding height, combining strength with comfort on rugged terrain.
  • Teflon Pads: Integrated to minimize noise and squeaks for a quieter ride.
  • Polyurethane Bushings: Included with springs for durable performance and reduced deflection over time.
  • Tire Compatibility: Supports up to 33" x 12.5" tires for improved ground clearance and aggressive look.
  • Shocks Not Included: Factory front & rear shocks must be replaced with extended shocks to install properly; select extended shocks in the options if you haven’t already.
  • Warranty: Backed by Tuff Country’s limited lifetime warranty for long-term confidence.
  • Vehicle Fitment Notes: Specifically designed for 1973–1987 3/4-ton GM 4WD models; will not fit diesel engine configurations.

The 13720K kit brings practical, real-world benefits: a taller, more capable stance for better approach and departure angles, room to run larger tires, and a ride that remains controlled thanks to EZ-Ride leaf springs and durable polyurethane bushings. With a proven 25+ year track record, Tuff Country combines engineering rigor with value, making this lift kit a thoughtful upgrade for restored or daily-driven GM 4WD trucks and Suburbans.
