3.73 Ring and Pinion Gear Set

The USA Standard Gear ZG SPRINTER-373K is a rear ring and pinion gear set designed for Chrysler 8.5-inch rear differentials. It offers a 3.73 gear ratio, providing an upgrade over stock specifications. USA Standard Gear ensures that all sets are subjected to rigorous in-house quality evaluations, covering dimensional, material, and fitment testing, to guarantee they exceed OEM standards. This gear set is compatible with 2003-2006 Sprinter 2500 and 3500 models, including both Dodge and Freightliner variants. The set includes the necessary installation kit for a complete replacement. The seller emphasizes that while they strive for accurate fitment information, it's the buyer's responsibility to confirm compatibility. If a fitment issue arises due to an error on their part or a misrecommendation from their sales team, they will work to resolve it, potentially waiving restocking or return shipping fees if the item is in like-new condition. Returns require authorization and must be made within 30 days of receipt, with items shipped back within 10 days of approval.
