Overview
The Alloy USA D44488JLX is a rear Dana 44 ring and pinion gear set with a 4.88 ratio and a 220 mm ring gear. It is the rear-axle version of the Alloy USA 4.88 Dana 44 set and is built to replace the gears in a rear Dana 44 housing, not in a front axle.
Alloy USA says that a set like this restores performance lost after larger tires were fitted to a Wrangler or other four-wheel-drive vehicle. Numerically higher gearing gives more pulling force at low speed, so the 4.88 ratio is aimed at owners who have changed their tire size. The company presents this as the reason to re-gear, and the exact effect depends on the tires and the vehicle.

Vehicle fitment
Alloy USA does not name a vehicle, model or year for this set. It is for a rear Dana 44 housing with a 220 mm ring gear and a 4.88 ratio. The product is marked universal fit, but a ring and pinion is sized for one axle, so confirm the housing and ring gear size before ordering. Confirm your vehicle’s year, model and trim before ordering.
Check the rear axle housing and ring gear diameter before ordering. This set is not a universal part.
Installation notes
A ring and pinion set should be installed and set up by a professional, with backlash and tooth contact checked before the axle is returned to service. Expect a break-in period after the gears are changed.
