Overview

It utilizes advanced gear geometry to minimize parasitic drivetrain losses, allowing for efficient power transfer to the ground. The maintenance-free design operates without the need for special fluids.
Show original supplier description
The MFactory Helical Limited Slip Differential provides a performance advantage for Honda K-series vehicles by ensuring smooth, constant power distribution to the wheels. This 2nd generation helical design is engineered to be lighter and more efficient than standard torque-biasing differentials. It is manufactured from forged high-nickel-chromium-molybdenum steel and features imported Japanese SAE 4320 and SAE 9310 steel, which is double-tempered, sub-zero treated, and shot-peened for increased surface hardness and shock load resistance. Designed using Solidworks 3D CAD and Cosmos FEA software, the differential is optimized to reduce parasitic drivetrain losses, with race transmissions utilizing these components typically seeing a 1-2% increase in power transfer. Professional installation is required to maintain the MFactory limited lifetime warranty. Note that this component does not fit models previously equipped with an OEM Viscous LSD. Please confirm your transmission type prior to purchase, as compatibility depends on specific vehicle configurations.
