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 -300F, 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

What do we think guys ???
Never heard of Mfactory seems a fair price with bearings include ???

 

Our company was established in 2004, with our LSD's being offered to the market since 2008. Although we are new to the VAG market, we have been around for a good few years

 

Have you got a diff for the 02J and 02S, are they compatible?

Do the diffs come with the drive gear for the speedo?

 

Not at the moment, only for the 02M/02Q and 02E.

We are looking at making a fitment for the older 02J, but depends on if we can get enough interest.

 

02J's are now under production, and will be 2-3 months away.

For those attending Autosport at the NEC, feel free to stop by our booth: 8406

 

More choice, must be good!

Can you tell me the weight of a 02j diff ?

The 02J is still under development, but if it is anything like the 02M/02Q, probably around 7kg or thereabouts.
