Product Description

The Revolution Gear & Axle REV-JK-NON-456 gear package is engineered specifically for the 2007-2018 Jeep Wrangler JK Non-Rubicon models with Dana 30 front and Dana 44 rear differentials. With a 4.56:1 ratio, this kit boosts performance for larger-tire setups, lifts, towing or off-road use where the stock 3.21/3.73 gearing falls short.

Built from high-grade 8620 alloy steel and heat-treated for durability, the ring and pinion gears are precision lapped for quiet, smooth engagement and long service life. The inclusion of full front and rear sets plus master install kits makes this a comprehensive upgrade solution - streamlining the rebuild process and improving drivability for owners of JK Non-Rubicon Wranglers.

Installation should be carried out by a qualified technician using proper differential setup tools - bearing preload, backlash, and gear-pattern must be set correctly for best results. Fitment is confirmed for the years listed; coverage beyond 2018 or other chassis/models is unconfirmed at this time.
