Ring and Pinion Kit for JL & JT 2018-ON D44F/D44R 4.88
Upgrading to 37s or 40s turns your Jeep Wrangler JL or Gladiator JT Rubicon into an off-road monster—until you step on the gas and feel the sluggish acceleration, hunting transmission gears, and lost low-end crawl speed. Re-gearing isn't just an upgrade; it’s an absolute necessity.
The Motive Gear Differential Ring & Pinion Front and Rear Complete Kit is engineered to restore factory power delivery, optimize crawling performance, and take the strain off your entire drivetrain. Built for heavy-duty AdvanTEK Dana 44 axles, this all-in-one package delivers the rock-solid reliability you need when you're miles away from pavement.
Restores Lost Power & Drivability: Bigger tires drain your engine's power band and cause constant highway gear-hunting. This kit corrects your final drive ratio, restoring snappy throttle response and smooth shifting.
Superior Crawl Control: Higher numerical gear ratios maximize low-end torque, letting your Rubicon creep smoothly over technical rocks and steep inclines without lugging the engine or overheating the transmission.
Heavy-Duty Metallurgy: Precision-cut from heat-treated 8620 steel, these ring and pinion sets are engineered to handle extreme torque loads, high impact, and harsh off-road abuse without failing.
All-in-One Front & Rear Package: Eliminates guesswork by providing perfectly matched gear sets for both front and rear axles in a single package, ensuring balanced performance and simpler installation.
Protects Your Drivetrain: Re-gearing takes excessive stress off your motor and transmission, preventing premature mechanical wear and thermal breakdown caused by pushing heavy, oversized tires on stock gears.
