MFactory LSD?
Is anyone running one of these MFactory Helical LSDs?
Helical LSD I know they are popular with the honda crowd, even in 700hp or so drag civics. I'm told its more or less a clone of a quaife. Does anyone know if the performance is comparable?

They are Chinese clones of Quaifes. We looked some over many years ago and found lots of quality control issues but if those are addressed they can be as good as the original. However if they are in the $700 range and a Quaife is only $300-$400 more then why bother.

Paying 50% more isn't exactly "why bother" territory for me. If the practical difference is not much more than a name then it is worth it to me to save that money for other things.

What you risk is reliability and quality of service. Who knows if they'll back their product if it fails and what the failure rate actually is. A lot more research will have to be done.
Personally I'd rather pay more now and not have to worry than risk having to buy another LSD in the future that might just fail again. Do it once, do it right.

This should be all you need to know in order to make the proper decision. And the proper decision is to stay away.

I have found in life that there are a few times you can afford to be cheap & I understand people have budgets so let me break this down a little. So you save $300-$400 initially Like the DR. said, they have actually inspected & "found lots of quality control issues" Knowing Chinese business practices pretty well (inside track stuff) I would not want to hope they fixed those issues. If this diff decides to let go, what else is going with it? Let me help Ring & Pinon $$$, new carrier & pinion bearings, seals. did it decide to frag & penetrate the diff cover/ Add more $$$. Did it do what it really shouldn't as a limited slip & total lock up take an axle stub or 2 with it? $$$ Oh & do you need to pay someone to install it all? $$$. This adds up to far more than the $300-$400 saved each $ is a actual place holder on what it will cost. What about the tow bill & your down time $$-$$$
I have seen plenty of diffs grenade & installed plenty of gear sets to know that this is not an area I would buy an inferior product. Most people who install a performance diff have a plan to push the car. Will you take the gamble on how long this will last for you? personally I would wait until the other option became into your budget or saved for it. Do it right, not again! Good luck

I will buy some chinese stuff. BUT if it has anything to do with heat treated metals. I stay far away from the chinese stuff then. They don't know how to heat treat metal! And LSD's have alot of heat treated metals in them.

I'm also curious what specific issues you saw with the mfactory diffs.

Anyways, according to an mfactory dealer I just contacted, apparently their 350/370Z diff is new and not for sale for a couple months.

That is correct, we do not currently have the 350z LSD available, as it is still under development.
DR_: Our Helical LSD is not a chinese clone of the Q****e. They did not invent the Helical LSD; Gleason did, and ours is based off the Gleason design (as is the Q****e. If ours is a clone, so is theirs), and every model we make uses an oem differential as the base reference to ensure perfect fitment. As for quality control issues, we take this very seriously. Please could you PM me with details of the issues you were having/had? So far to date, from thousands of LSD's sold, we have not had any serious quality issues, so find it strange that you had issues and never contacted us. Are you sure you're not confusing our brand with OBX? We are not the same as OBX, far from it. Moderators: I am in contact with the admin regarding a vendor account |

Sub'd because I Am Curious (Yellow).
I know absolutely nothing about MFactory but will give them a point for responding. Not a fast response but reasonably quick considering they probably don't monitor this site.

I appreciate the manufacturer chiming in. When you say that "Our Helical LSD is not a chinese clone of the Q****e" are you saying that you did not clone the Quaife diff, or that it's not made in China?
