New Center Section FS 6.66 Ratio 31 Spline L/W

The New Center Section FS 6.66 Ratio 31 Spline L/W is a heavy-duty differential center section designed for high-torque applications in off-road and performance vehicles. This component is essential for operators and vehicle enthusiasts who require robust drivetrain components capable of withstanding extreme stress in demanding environments.

The 6.66 gear ratio provides aggressive acceleration and climbing capability, making it suitable for low-speed, high-torque scenarios typical in overland and recovery operations. Featuring a 31-spline configuration and a full-spool (FS) design, this center section locks both axle shafts together for maximum torque delivery and eliminates wheel slip during challenging terrain transitions. Constructed from heat-treated steel, it ensures consistent performance under high-load conditions.

Operators of heavy-payload vehicles, tactical support platforms, or performance builds will find significant benefits from this differential center section. Its substantial weight of 75 lbs reflects the durability required for professional-grade drivetrain performance, making it a reliable choice for severe-duty applications.
