GRIP LS Ford 9in 31 Spline

The GRIP LS Ford 9in 31 Spline is a performance limited-slip differential designed specifically for Ford 9-inch rear axles that utilize 31-spline axleshafts. This product is essential for street machines, drag cars, and high-horsepower muscle vehicles that require enhanced traction off the line. It is ideal for builders of hot rods, restomods, or performance trucks looking to upgrade their traditional Ford 9-inch housing.

The GRIP LS unit features a friction-based limited-slip design that automatically biases torque to the wheel with the most traction while allowing for slight differential rotation during cornering. This design preserves drivability on street applications and provides controlled power delivery to both rear wheels simultaneously. The aggressive friction pack tuning ensures consistent engagement across varying load conditions, making it suitable for burnouts, launches, and cornering.

Builders choosing the GRIP LS Ford 9in 31 Spline will benefit from a straightforward installation process, as it replaces the open carrier without the need for custom fabrication or bearing replacement. This product is designed to mate directly with existing axleshafts and housing internals, making it a plug-and-play solution for performance enthusiasts. With its robust design, the GRIP LS differential is a reliable choice for those looking to maximize traction and performance.
