BTKUSA Dual Differential Mount G80M3/G82M4/G87M2 S58

BuiltToKillUSA G8X Differential Dual Mount

The BuiltToKillUSA Differential Dual Mount is designed to reinforce one of the G8X platform’s known weak points. By utilizing the unused factory secondary bushing location, it adds a second support to help keep the differential stable under hard acceleration, aggressive launches, and spirited driving. This reduces flex and sharpens overall driveline response.

Installation is extremely simple with no disassembly of OEM components required. Insert the bushing, assemble the mount onto the differential, and you’re done—delivering unparalleled driveline support.

What Is a Dual Diff Mount and How Can It Benefit My Build?

1. Improved Load Distribution

• The mount ties both sides of the differential into the subframe instead of relying on a single ear or bushing.
• Spreads torque load more evenly during hard acceleration, launches, and aggressive shifting.
• Especially important on higher-torque vehicles where the differential tends to rotate upward under load.

2. Reduced Differential Movement

• The billet bridge and side arms significantly reduce differential wind-up and rotation.
• Less movement results in more consistent driveline geometry.
• Direct benefits include:
  • Reduced wheel hop
  • More predictable traction
  • Less shock loading on axles and bushings

3. Structural Rigidity

• Constructed entirely from U.S.-made 6061 machined aluminum.
• Complete assembly weighs only 20 oz.

Type III Hard Anodized Finish

Our Type III hard anodized coating, also known as hard coat anodizing, is an electrically applied surface treatment that significantly enhances the aluminum’s performance and durability.

Key Benefits Include

• Extreme hardness and wear resistance—often compared to hardened steels in surface properties.
• Thick protective oxide layer resistant to scratching, abrasion, and corrosion.
• Enhanced durability under stress for high-use performance applications.
• Excellent chemical resistance and improved lubricant retention.

This coating complies with MIL-A-8625 Type III standards, considered a true military-grade finish for aluminum components subjected to demanding conditions.
