Overview
The Rough Country Dana 44 ring and pinion set, part 54445622, is a 4.56 ratio gear set for the rear axle of the Jeep Wrangler JK. Based on the product title and description, it fits the Jeep Wrangler JK from 2007 to 2018.
After a lift and larger tires, the factory gear ratio is off, so the driveshaft and engine turn more slowly and power can feel weaker. A 4.56 ratio is used to restore low-speed pull.
After a lift and larger tires, the factory gearing sits outside its intended range, which slows the driveshaft and engine and can cost power and fuel economy. A 4.56 pair restores that low-speed pull. The gears are smooth-finished, durable and run cooler and quieter than some alternatives, and they carry a 10-year warranty against defects. Confirm your tire size and transfer case setup before choosing a ratio. A 4.56 set performs best with a full install kit and a tooth pattern check.
Key features
- Smooth-finished gears that run cooler and quieter than some alternatives
- 4.56 ratio for the rear Dana 44
- Durable construction
- 10-year warranty against manufacturing defects
Gear ratio and install planning
Changing the ring and pinion ratio changes how many times the driveshaft turns for each turn of the wheel. A numerically higher ratio favors low-speed pull and crawling, but it also raises engine speed at highway speeds. Driving habits and tire size decide whether that trade is worth it.
Setting up a new gear set takes more than swapping gears. Pinion depth, carrier bearing preload and backlash all affect how the teeth wear and how quiet the axle runs. Gears set poorly can be noisy or fail early, so a careful setup and tooth contact check matter as much as the gears themselves.
- Verify backlash with a dial indicator
- Check pinion depth before final assembly
- Use fresh bearings, seals and shims
- Re-check the gear oil level after the first drives
