Highlights:
While the stock gearing on the 2019-2021 Rangers is already a 3.73 ratio, the factory ring gears are welded to the stock differential, which is a huge problem if you're looking to run an aftermarket limited-slip or locking rear diff. Spicer's Rear Dana M220 Ring-and-Pinion 3.73 gears are the perfect way to keep your stock rear-end gear ratio while adding an aftermarket differential to give your 2019-2021 Ranger a boost in traction and off-road performance. Spicer's 3.73 gears drop right into place of your Ranger's stock ring-and-pinion gears and come with drilled-and-tapped mounting surfaces that allow for a proper bolt-on install onto your aftermarket differential of choice. Spicer's gears are built with quality in mind and will provide your Ranger with quiet and smooth operation while handling any application that you have in mind.
Each set of Spicer Rear End Gears is built from the ground up to provide your Ranger with smooth function and reliable operation. The gears are made out of high-quality gear steel that's carefully machined for a perfect fit. The teeth are hobbed and shaved to provide a smooth mesh between the ring and pinion. The gears are then both heat-treated and shot-peened for extra strength and awesome levels of durability. The Spicer gears install right into place of your factory rear-end gears, but feature tapped backs that allow for the installation of the gears on aftermarket differentials, though they can also be welded to OEM differentials like the factory gears.
