MFactory Helical LSD Focus ST 2013+
Ford Focus ST LSD
Gain a prominent advantage over the competition with the MFactory Helical Limited Slip Differential. Through the smooth and constant distribution of power to the wheels, the MFactory Helical LSD puts the power-to-the-ground and maximizes your vehicle's traction. A must for any race car, be it Street, Strip or Track!
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!
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.
