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 maximises 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

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!

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 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

Came delivered as advertised straight to my doorstep! So convenient! Carbonation was great and no difference in taste if I wasted gas and went to the store. Great value!

Fresh crisp and refreshing
Flavor Name: Diet Coke, Size: 12 Fl Oz (Pack of 12)
I’d love Diet Coke. That’s just the type of person I am. I was pleased to see the Amazon sold this. It was a great value for the money. I got the 12 ounce cans in the 12 pack. The flavor was great. There was no problem with leakage or smash cans and I’m just very happy I was able to purchase this through Amazon. ..

Gotta have my Diet Coke
Flavor Name: Diet Coke, Size: 12 Fl Oz (Pack of 12)
What can I say? I don’t drink coffee but Diet Coke is my daily morning fix! I love Diet Coke in the can better than the bottle unless I come across some bottles that have good carbonation, but they always seem to be a little lacking! Not so most of the time with the cans, but I love the taste of Diet Coke!
