Overview

The MFactory Helical Limited Slip Differential is a 2nd generation torque-biasing differential designed to improve traction and power delivery. It features a diamond-cut finish from forged high-nickel-chromium-molybdenum steel for precise fitment and durability. Utilizing advanced Solidworks 3D CAD and Cosmos FEA software, its gear geometry minimizes drivetrain losses, potentially transferring 1-2% more power to the ground than competitors.

Constructed from imported Japanese SAE 4320 & SAE 9310 steel, this LSD is forged, double tempered, and super sub-zero treated for maximum toughness. The helical design offers maintenance-free operation without requiring special fluids or rebuilds, and its lock-free nature ensures no adverse effect on steering response.

Show original supplier description

The MFactory Helical Limited Slip Differential provides a competitive advantage by maintaining constant power delivery to the wheels. This 2nd generation torque-biasing unit is forged from Japanese SAE 4320 and SAE 9310 steel, utilizing advanced shot peening and sub-zero treatment to ensure durability under the high shock loads typical of drag racing. Designed with Solidworks 3D CAD and Cosmos FEA software, this unit features refined gear geometry that minimizes parasitic drivetrain losses, typically allowing for a 1-2% increase in power transferred to the ground. The helical design is maintenance-free, eliminating the need for the special fluids and rebuilds required by traditional plate-type limited-slip differentials. Compatibility is confirmed for Honda H22A and F20B engines, including 1991-2001 Honda Prelude models. Professional installation is mandatory to qualify for the manufacturer's limited lifetime warranty on materials and workmanship.
