Description

ReadyLift gives your 2025-2026 Trail Boss or AT4 a massive 6-inch lift with durable Falcon shocks.

Take your 2025-2026 Trail Boss or AT4 deeper into the woods with the ReadyLift 4-inch Big Lift Kit. This complete upgrade pairs a 6-inch total height gain with robust Falcon 2.1 shocks for smooth, controlled off-road action.

  • Massive Clearance: Combines a 4-inch ReadyLift lift with the factory 2-inch suspension for a total 6-inch lift.
  • Undercarriage Shielding: A full-width front skid plate made from thick 3/16-inch plate steel protects your underside from sharp rocks.
  • Built to Last: Boxed steel cross members handle heavy off-road loads while keeping your chassis locked and square.
  • Reinforced Differentials: New 1/4-inch boxed plate steel drop brackets feature a double gusset and center rib to resist twisting.
  • Smooth Ride Quality: Integrated Falcon 2.1 shocks absorb rough trail bumps for a controlled ride on tough terrain.
  • Precision Fitment: Engineered specifically for the 2025 and 2026 1500 Trail Boss and AT4 models for a stress-free install.
  • Compact Dimensions: The complete 225-pound kit measures 48 x 25 x 13 inches for easy handling and storage.
