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.
Lifting your iconic Jeep Cherokee XJ and fitting 31s, 33s, or bigger tires gives it the legendary look and clearance it deserves—but factory gears quickly show their limits. You’re left with sluggish acceleration from a stop, an automatic transmission continuously searching for power on highway inclines, and a complete loss of low-speed crawl control off-road. Re-gearing isn't just a modification; it’s the ultimate key to restoring your XJ’s legendary reliability and driveability.
The Motive Gear Differential Ring & Pinion Front and Rear Complete Kit is built to solve these exact performance losses for Cherokee XJ owners. Engineered specifically to match popular XJ setups—such as the High-Pinion Dana 30 front axle paired with either a Chrysler 8.25" or Dana 35 rear axle—this kit corrects your final drive ratio. Restoring your engine’s target power band gives you snappy street performance, reduced heat buildup, and precision torque control on technical rock trails.
