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). This myth has been further perpetuated by our competitors of whom have limited understanding of how a Torsen-Style LSD functions. This no-load situation does not apply to 90% of users. For the other 10%, there is a simple solution to the problem that our competitors will not tell you; simply tap your brake pedal.

Manufacturing Process
- SAE9310 Bar Stock imported from Japan to ensure the purest steel grades
- All MFactory components are Forged. We do not use inferior Cast or Billet processes. Forged components are upto 30% stronger & tougher than the equivalent "Billet" component. Click here for further details
- Advanced material processing, heat treatment & finishing techniques offer superior strength, durability and quality
- Primary Heat Treatment: After the forged parts come off the press, they are Normalized and Annealed to relieve residual stresses and make them machine workable
- Machining: After the forged blanks are completed, we use Industry-leading Multi-Axis CNC and CAM equipment to machine the parts
- Secondary Heat Treatment: State-of-the-art Case Hardening procedure achieved via computer-controlled Gas Carburization and Quenching
- Double-Tempering: A superior heat treatment technique used to decrease the brittleness and increase the toughness of our parts
- Surface Grinding: Through the use of our state-of-the-art diamond grinding machines, we ensure all parts are smooth, precise and free of burrs
- Super Sub-Zero Processing: An advanced treatment technique whereby the parts are cryogenically hardened at -300°F, realigning the steels crystalline structure for maximum strength, then heat tempered again for a 3rd time to ensure maximum toughness (resistance to fracture)
- Micro-Peening: Our final treatment stage, the parts are subject to a high speed shot blast with our proprietary micro media, creating a super smooth surface

Any sale (s) going on right now?

In stock?

I chose one on the website after calling in to make SURE it was in stock. It's in stock, but in Taiwan and will be shipped from them. In the checkout cart it lists a charge of $46.00 for shipping. Still only a 3-5 business day turnaround, which is impressive as hell, to me.

Would that $46.00 be due to the part not being located here in the States? Just wondering as your original post says "All prices include Bearings, Bolts and FREE Shipping within North America.". Also, does it still come with all bearings and bolts needed for install?

Ordered it on Friday afternoon, it's on the way to my post office right now. Excellent customer service by Stephen and the young lady I talked to on Friday in California.

I'll have a write up shortly.

I installed the MFactory DSG LSD in my car the other week. Just been driving it around and testing it.

It really changes the way the car performs. Is it better than the other options? No I would say it works just like any other quality Helical LSD. A good LSD is a good LSD. What this does offer is a really well priced option and great customer service at pricing that makes putting a LSD in our cars easier.
