Jeep Wrangler Differential Install Kit - Rear - Revolution Gear & Axle - Dana 44 Thick Timken 4.88 Ratio - `03-`06. This rear gear package is specified for 2003–2006 Jeep Wrangler TJ models with the Dana 44 thick rear axle and uses Timken-specified components in a 4.88 final drive ratio.

Designed for owners swapping gears or refreshing a rear differential, this Revolution Gear & Axle package provides the correct 4.88 ratio ring and pinion fitment for the Dana 44 thick housing found on TJ Wranglers. The ratio is a common choice for taller tire setups or when compensating for axle upgearing, offering improved low-end response and drivability without changing transfer case settings. The package is intended to match factory axle specifications for fit and function.
