The Dana Spicer 504096-1 is a complete wheel differential side gear kit for Dana D170 and D190 differentials, also cross-referenced under Mack number 2104-504096. The kit supplies every internal spider nest component needed for a full differential rebuild in a single package: two side gears (10166833), four pinion side gears (10166834), one differential spider (131039), four spider/pinion thrust washers (300HS100-1), and two side gear thrust washers (HS108-1). Having all mating components from a single source keeps running clearances consistent and avoids mixing generations of gear geometry. Call us to confirm proper fit for your specific axle configuration.
