Overview
The G2 Axle and Gear 4-TJ2-456 is a 4.56 ratio front and rear ring and pinion kit for non-Rubicon Jeep Wrangler TJ models, with a Dana 30 front axle and a Dana 44 rear axle. The TJ chassis code covers the 1997-2006 Wrangler.
One kit supplies both the front and rear gear sets, so the ratio is changed at both ends of the driveline in one job. The matched master installation kits for each axle come in the same package. The carriers are not included and are sold separately.
Key features
- Front and rear 4.56 ratio ring and pinion sets
- Dana 30 front axle and Dana 44 rear axle
- Matched front and rear master installation kits included
- Computer heat treated 8620 steel
- Double shot peened and double lapped
Choosing a TJ ratio
The 4.56 ratio is a numerically higher gearing, which means more torque reaches the wheels at low speed and the engine turns faster at a given road speed. That trade suits trail driving and heavier tires, though highway cruising will feel busier. Consider how the vehicle is used before committing to gearing that changes both axles at once.
A ratio change is more than a gear swap. The pinion bearings, carrier shims and master installation kits all need to be correct, and the front and rear carriers should be checked for wear. If a Wrangler has been fitted with larger tires, check the speedometer calibration after the swap, since gearing changes the reading.
- Check the carrier condition before reusing it
- Match each master installation kit to its gear set
- Verify speedometer accuracy after the change
- Plan a break-in period on the new gears

Vehicle fitment
The kit fits the Jeep Wrangler (TJ) from 1997 to 2006 and is made for non-Rubicon models with a Dana 30 front and Dana 44 rear.
The TJ years run 1997 to 2006, so YJ, LJ and JK Wranglers fall outside that range. Rubicon models are outside this non-Rubicon set, so their axle layout needs checking before ordering. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Set pinion depth and gear backlash once the new ring and pinion is in the carrier, and keep each master installation kit with its matching gear set. An incorrect setup will wear the new gears quickly, so have the carriers checked with the proper tools.
What’s included
Front and rear 4.56 ring and pinion sets, plus matched front and rear master installation kits.
Not included: The carriers are sold separately.
