The Yukon 4.88 ring-and-pinion set for Dana Spicer S130 axles is a high-ratio replacement featuring a 12.25-inch ring gear and 34-spline pinion. Yukon finishes gear teeth to reduce friction and heat and builds to OEM-spec fitment for reliable installation. This 4.88 ratio provides stronger low-speed torque for heavy loads or oversized tires, and the set is manufactured to stand up to demanding use while offering consistent drivetrain behavior.
