The Yukon Gear & Axle Dana 30 JK Front ring and pinion set in 4.88 ratio is engineered for Jeep Wrangler JK owners running 35" tires who want to restore lost power and throttle response. The JK's reverse-rotation Dana 30 front axle requires a specific reverse-cut gear set — this Yukon set is purpose-built for that application, maintaining correct differential operation while delivering the gear ratio needed for larger tires.

Why Re-Gear to 4.88?

Lifting a JK and fitting 35" tires effectively raises your final drive ratio, making the engine work harder and reducing acceleration. Re-gearing to 4.88 restores factory-equivalent performance with 35s, improving throttle response, fuel efficiency under load, and towing capability.
