Motive Gear D44-456GX Dana 44 Ring and Pinion Set 4.56 Ratio Thick Gear

The Motive Gear D44-456GX is a high-performance differential ring and pinion set engineered for the Dana 44 axle, featuring a 4.56:1 gear ratio and a thick ring gear profile. This set is purpose-built for off-road performance and aggressive gear swaps, delivering the torque multiplication needed for larger tire combinations and demanding trail use.

This is a thick ring gear configuration, requiring a 3.73 and numerically lower ratio carrier. The ring gear is dual-drilled to accept both 3/8" and 7/16" ring gear bolts, providing added installation flexibility. The set features a 41-tooth ring gear and 9-tooth pinion (41:9) combination to achieve the 4.56 ratio.
