  • Diamond Cut to exacting tolerances from Forged High-Nickel-Chromium-Molybdenum Steel
  • Perfect fitment & finish ensures hassle-free installation & maintenance, each and every time
  • Designed using leading-edge Solidworks 3D CAD & Cosmos FEA software
  • Advanced Gear Geometry minimizes parasitic drivetrain losses. Race transmissions built with MFactory components transfer, on average, 1-2% more power to the ground over our competitors!
  • Stress Tested on loaded dynos
  • Ensures our differentials are strong enough to handle the shock loads encountered during racing, yet also durable enough to handle the variable loads encountered during day-to-day driving.
  • Multiple Stages Available (Honda & Mazda)
  • Users can choose (and upgrade) between the various Stages available, which determine the Bias Ratios. With the MFactory Helical LSD, upto 75% torque can be transferred to the one wheel! A must-have for serious road-racers.
  • 2nd Generation Design
  • The MFactory v2 Helical LSD is lighter, stronger and more efficient than any other Helical LSD on the market today!
  • Covered by the MFactory Lifetime, Globally Transferable Warranty
  • Whether used on the Street, Strip or Track, all MFactory Helical LSD's come with a Lifetime, No-Hassle, Globally Transferable Warranty
  • No-Load/One-Wheel Syndrome
  • A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a simple solution to the problem that our competitors will not tell you; simply tap your brake pedal lightly with your left foot.

     Let us know if you need to add differential bearings and we can assist with that.
