Features

• 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 Torque-Biasing Differential on the market today!
  
• 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 very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake.
  
  
• Covered by the MFactory Feel The Torque 30-Day Money Back Guarantee!
  An Industry First! If you do not feel the difference after installing your new Limited Slip Differential, you may return the product to us for a full refund (excluding shipping costs) within 30 days of the purchase date
