Overview
The G2 Axle and Gear 5.13 ring and pinion, part G/21-2050-513R, replaces the gears in a front Dana 30 axle. Based on the product title and description, it fits Jeep Wrangler JL models from 2018 to 2026 and Wrangler JK models from 2007 to 2018.
At 5.13 this is the most numerically aggressive front Dana 30 ratio in this pair of sets. It multiplies the most torque at low speed and turns the engine faster on the road.
Key features
- Forged 8620 steel
- Precision-machined to OE specifications
- Heat treated to endure harsh conditions
- Lapped mating surfaces for a smoother finish
Dana 30 front axle care
The Dana 30 front axle relies on its pinion seal, carrier bearings and differential fluid to keep the gears running cool and quiet. Check for leaks at the pinion seal and axle shafts during routine service, and address any seepage before it reduces fluid level. Low fluid accelerates wear on gear teeth and bearings, particularly under heavy towing or off-road loads.
Front axle components also share load with the driveline. Inspect the u-joints or CV joints, the tie rod ends and the front hubs when the gears are serviced, since looseness in these parts can change gear mesh and make noise that is easy to mistake for a gear problem.
- Check the pinion seal for leaks
- Inspect U-joints or CV joints
- Replace differential fluid on a regular schedule
- Listen for whine that changes with load
