High Quality Dana 30 Differential for Case Assembly Kit with 3.73 to 4.10 Ratio Premium Casting Services Product

For off-road enthusiasts and performance builders seeking to unlock superior torque and crawling capability, the High Quality Dana 30 Differential Case Assembly Kit for 3.73 to 4.10 ratios is an essential upgrade. Engineered specifically for the demands of lower gearing, this premium kit provides a robust and reliable foundation for Jeep Wrangler TJ/YJ, Cherokee XJ, and other vehicles utilizing the Dana 30 platform. It is the go-to solution for those upgrading their axle ratio for larger tires, improved rock crawling performance, or enhanced towing power.

Premium Material for High-Stress Applications
This differential case is precision-cast from high-grade, heat-treated ductile iron. This material is selected for its superior tensile strength and exceptional impact toughness, far exceeding standard cast iron. This enhanced durability is critical when running 3.73 to 4.10 numerical gears, as these ratios transmit increased torque loads through the differential assembly. The robust construction ensures the case can withstand the shock loads encountered during aggressive off-road use without flexing or failing, protecting your ring and pinion investment.

Precision Performance for Demanding Gear Ratios
The kit is meticulously engineered to maintain perfect gear alignment for numerically higher ratios. It includes the differential case, high-capacity spider gears, a hardened cross pin, and premium thrust washers. This complete assembly ensures optimal contact between the ring gear and pinion, which is paramount for achieving quiet operation, efficient power transfer, and long-term reliability under the increased stress of 4.10 and similar gearing. It eliminates the weak link in your drivetrain upgrade.

Advanced Casting and Machining Process
Manufactured using advanced lost-foam or shell molding casting processes, the case achieves near-net shape with excellent dimensional stability and a smooth, clean surface finish. Each casting is then precision-machined on CNC lathes and mills to exacting tolerances. This guarantees a perfect fit within the carrier, correct ring gear bolt alignment, and proper bearing seat dimensions, ensuring a hassle-free installation and long-lasting performance.

Choose this High Quality Dana 30 Differential Case Assembly Kit to complete your gear upgrade with confidence. It delivers the foundational strength required for high-performance 3.73 to 4.10 ratio applications, ensuring your build is capable, durable, and reliable on the toughest trails.
