Frequently Asked Questions on Torsen differentials!




What is the warranty for Torsen aftermarket differentials?

Please contact your point of purchase Torsen approved distributor for relevant warranty information.






If you buy one from Ford Motorsports there is no warrenty...here is an e-mail that Terry Haines sent me regarding that.

...listed in the 2004 Ford Racing.....refer to page
3,bottom of page in red panel 'FORD RACING PERFORMANCE
PARTS ARE SOLD WITH NO WARRANTY'...Quaife has a lifetime warranty!!!





So with torsen, the warrenty is limited to the distributer you purcahesed it from...>Quaife, warrenties it for the life time directly from quaife.

Choice is yours.

It is not "either" ratio though.

Torsen is 3 to 1 biasing ratio.

Quaife is 2 to 1.


That means the Torsen can handle more torque "comparably" and bias it between wheels before "giving in" and letting the wheel with less grip spin.


For example if 200 TQ caused a Quaife to "give in" it would take 300 TQ for a Torsen to "give in" with all other conditions being equal.

This would show up most notably in cornering situations.

I just have to laugh when reading some of these posts.
What's with all the newbies coming on here not knowing jack-squat about the platform, but then turn around and say they're going to crank out mondo hp and are worrying about braking a LSD differential. Time and time again I've heard this story then once the cost of even hitting 300hp is realized by these kids, they shrink away into the darkness from whence they came.

Please!

There's 3 cars now, running over 400hp crank and a bunch running at over 300hp crank, all with LSD's and none with any LSD diff issues. Seeing as 450hp is probably going to be about it for the Duratec (maybe 500hp, though I doubt it), why is this question even out there? The damn synchros and drive gears in the gearbox (not to mention the drive shafts!) will crap out way before the LSD even sheds a tear.

1. 2 turbo'd 2.5L and a S/C'd 3L. Tom's budget 3L turbo is so close to 400 crank it should count.
That number should grow in the next several months.

2. Suneil's is near 500 already. Estimated 490 crank with 401 wheels using 18% loss.

I expect 500 crank (410 wheels) to fall as well.

Is it manufactured by Quaife or Torsen? Nope Tochigi Fuji Sangyo. Hence the issues. No one on here with either LSD has had one fail.




The problem isnt WHO made it - its a spot weld system that breaks - you dont actually "break" anything in the actual machanical componentry of the LSD - you crack the welds on the case.
