Upgrade drivetrain performance with the Yukon Gear & Axle YG D30-411 high-performance ring and pinion gear set. Designed for standard-rotation Dana Spicer 30 differentials, this replacement gear set delivers dependable power transfer and OEM-focused fitment for street, off-road, and performance applications. The 4.11 gear ratio can help optimize acceleration and traction performance when matched with the vehicle’s engine output, tire size, and intended use.
Yukon Gear & Axle uses high-grade steel, advanced heat-treating techniques, and precise quality-control processes to produce ring and pinion sets built for strength and consistent operation. The gear tooth surface finish is engineered to help reduce friction and heat, while the fitment is designed to meet OEM specifications. This set is configured for applications that use a standard-rotation Dana Spicer 30 axle without a crush sleeve.
The Yukon Gear & Axle YG D30-411 includes a ring gear with a 7.20-inch diameter, 10 ring gear bolts, and a 26-spline pinion. It is suitable for select classic Volvo applications, including 1970–1974 Volvo 144 and 1970–1974 Volvo 164 models, subject to axle and vehicle configuration. Professional installation is recommended, including proper gear setup, backlash adjustment, bearing inspection, and lubrication. Yukon’s Y.E.S. Plan provides lifetime, comprehensive, no-questions-asked protection for the gear set for as long as you own the vehicle, according to program terms.
