Overview
The G2 Axle and Gear 3.73 ring and pinion, part G/21-2151-373R, is a front Dana 44 AdvanTEK gear set. The product title and description place it in 2018–2022 Jeep Wrangler JL models.
The 3.73 is the numerically lowest ratio of the front Dana 44 sets in this group. It keeps engine speed lower at highway speed, at the cost of less low-speed torque multiplication.
The front Dana 44 sits at the steering end of the driveline, and its ring and pinion has to match the front carrier and housing exactly. Confirm the axle location and type on your vehicle before the gears are ordered.

- Forged from 8620 steel for a strong base
