Dana Super 30 Standard Differential for Case Assembly 3.55 Ratio Casting Services Product

For off-road enthusiasts and technicians seeking to upgrade or repair their front axle system, the Dana Super 30 Standard Differential Case Assembly with a 3.55 Ratio represents the pinnacle of strength and reliability. This critical component is engineered specifically for the heavy-duty Dana 30 front axle, commonly known as the "Super 30" upgrade. Manufactured through advanced casting services, this assembly is designed for vehicles requiring a robust differential with a popular and versatile 3.55 gear ratio.

High-Strength Material Composition

The integrity of this differential case begins with its material. It is typically cast from high-grade, heat-treated ductile iron. This material offers superior tensile strength and exceptional impact resistance compared to standard gray iron. The nodular graphite structure within the iron provides excellent fatigue strength, allowing the case to withstand the constant torsional stress and shock loads encountered during aggressive off-road driving and high-torque applications.

Performance and Engineering Excellence

The Dana Super 30 design is renowned for its larger axle tube and stronger components than a standard Dana 30. This differential case assembly is machined to precise OEM specifications to ensure optimal performance:

• Precision Gear Mesh: The case is engineered for perfect ring and pinion alignment with a 3.55 ratio, reducing noise and maximizing power transfer efficiency.

• Enhanced Load Capacity: Its robust construction supports the increased load-bearing requirements of larger tires and demanding off-road use.

• Optimal 3.55 Ratio: This ratio provides a perfect balance of low-end torque for crawling and highway-friendly RPMs, making it ideal for a wide range of tire sizes and driving conditions.

Advanced Casting and Manufacturing Process

This product is a result of sophisticated casting and machining processes. It is produced using precision sand-casting techniques to create a near-net-shape component with excellent structural integrity. After casting, each unit undergoes a normalizing heat treatment to ensure a uniform, stable microstructure, eliminating internal stresses. Critical surfaces, including the ring gear mounting flange and bearing cap seats, are then finished on CNC machining centers. This guarantees exact tolerances for a perfect fit and reliable, long-lasting performance.

Primary Applications

This Differential Case Assembly is specifically designed for:

• Dana 30 "Super 30" Axle Upgrades: A direct replacement for vehicles like Jeep Wranglers (TJ) and Cherokees (XJ) equipped or being upgraded with the heavy-duty Super 30 front axle.

• Off-Road Vehicle Rebuilding: Essential for rebuilds where strength and reliability are paramount.

• Gear Installation: Serves as the core foundation for professional mechanics installing a new 3.55 ring and pinion set.

Choose this precision-cast differential case to ensure your front axle assembly delivers the strength and performance demanded by the toughest trails.
