Description
Restores Lost 4.0L Power & Acceleration: Oversized tires alter your effective gear ratio, bogging down the legendary 4.0L inline-six and causing constant highway gear hunting. This kit corrects your final drive, giving you back instant throttle response and smooth cruising speeds.
Precision-Matched Front & Rear Packages: Tailored specifically for Cherokee XJ axle combinations (like High-Pinion Dana 30 front and Chrysler 8.25″ or Dana 35 rear), ensuring synchronized 4WD operation and perfectly matched ratios from front to back.
Maximum Trail Crawl Control: Deeper gear ratios optimize low-speed torque delivery, allowing your XJ to creep smoothly up steep inclines and over rocky obstacles without riding the brakes or stalling out.
Heavy-Duty Heat-Treated Construction: Precision-cut from high-strength 8620 steel, these ring and pinion sets are built to withstand sudden shock loads, extreme heat, and harsh off-road torque demands without teeth chipping or stripping.
Protects Engine & Transmission Life: Forcing your engine and AW4 automatic transmission to turn large tires on tall stock gears causes severe thermal strain and wear. Re-gearing takes the load off your drivetrain, helping extend vehicle lifespan and improve overall fuel efficiency.
