The American Axle & Manufacturing 115410GSK is a complete 4.10 ratio ring and pinion kit engineered specifically for 2019-2024 Ram 2500 and 3500 trucks equipped with the 11.5" 14-bolt rear axle. Rather than sourcing gear set components separately, this kit bundles the ring and pinion gear set along with the pinion nut, pinion shim, pinion seal, and crush collar, giving installers the core pieces needed to complete a gear swap in one package. The 41-tooth ring gear pairs with a 10-tooth pinion on a 32-spline pinion shaft, secured by a 12-bolt ring gear pattern, matching the demands of heavy-duty diesel and gas Ram platforms. As a premium-grade component from AAM, a recognized name in axle manufacturing, this kit is built for shops and enthusiasts who need dependable rear axle gearing for their 11.5" 14-bolt setup.
