2007-2013 Wrangler JK Front Differential for Case with Internal Parts Casting Services Product

For Jeep Wrangler JK owners and off-road specialists, the front differential case forms the critical foundation of the 4x4 drivetrain system. Our specialized casting services for the 2007-2013 Wrangler JK Front Differential Case with Internal Parts deliver OEM-quality components engineered to restore and enhance off-road performance, durability, and reliability. These precision-cast cases provide the perfect housing for ring and pinion gears while withstanding the extreme stresses of rock crawling and trail riding.

Premium Material Engineering
We manufacture differential cases using high-strength ductile iron (GGG50/60) specifically formulated for automotive drivetrain applications. This material delivers:

• Tensile strength of 500-600 MPa and yield strength of 350-400 MPa

• Exceptional impact resistance (≥12 J at -20°C) for handling shock loads

• Superior wear resistance against gear contact surfaces

• Excellent machinability for precision bearing surfaces

• Weight-optimized design maintaining structural integrity

Advanced Casting and Manufacturing Process
Our production integrates sophisticated foundry technology with precision machining:

Casting Process

• Resin sand molding with 3D-printed cores for complex oil passages

• Controlled pouring at 1420-1480°C ensuring proper nodularization

• Real-time thermal monitoring during solidification

• Stress relief annealing preventing dimensional distortion

Precision Machining

• CNC boring of carrier bearing journals (tolerance: ±0.015mm)

• Face milling of ring gear mounting surface (flatness: 0.03mm)

• Precision drilling of bolt holes (positional accuracy: ±0.1mm)

• Honing of pinion bore (surface finish: Ra 1.6 μm)

Performance Characteristics
Our differential cases deliver:

• Perfect compatibility with 2007-2013 Wrangler JK front axle specifications

• Support for gear ratios from 3.21 to 5.13

• Maximum torque capacity of 4,000 Nm

• Proper oil flow management for bearing and gear lubrication

• Optimized rib design for enhanced structural rigidity

Quality Assurance Protocol
Each case undergoes comprehensive validation:

• Magnetic particle inspection for surface defects

• Ultrasonic testing for internal integrity

• CMM verification of all critical dimensions

• Hardness testing (170-240 HB)

• Pressure testing of lubrication channels

Technical Applications
These cases are engineered specifically for:

• 2007-2013 Jeep Wrangler JK front axle assemblies

• Dana 30 differential platform

• Both standard and electronic locker configurations

• Off-road performance upgrades and OEM replacements

Our engineering team ensures perfect compatibility with:

• Original equipment ring and pinion sets

• Factory bearing and seal components

• Stock and aftermarket cover assemblies

• Both Rubicon and Sport model specifications

By combining advanced ductile iron metallurgy with precision manufacturing, we deliver differential cases that provide reliable performance in the most demanding off-road conditions. Each case maintains perfect gear alignment, ensures proper lubrication flow, and withstands the torsional stresses encountered during aggressive 4x4 operation, making them the ideal choice for restoration projects, performance upgrades, and professional repair applications.
