The Quaife ATB Differential comes with something else other's don't have:
a Limited Lifetime Warranty. This warranty applies even when raced!

Quaife ATB Differential Limited Lifetime Warranty
Quaife America Torque Biasing Differential Lifetime Warranty: Quaife America warrants each new Quaife ATB Differential against defects in manufacture, material, workmanship, and wear-out when used in the vehicle application for which it was originally designed, on any motor vehicle, under any and all operating conditions, including racing, for as long as the original purchaser, or any subsequent purchaser owns the differential. The original purchaser must complete and mail in the accompanying warranty registration form within 30 days of the purchase date to qualify for this warranty. The registrant must present a copy of this warranty together with a copy of the original receipt to the service outlet or parts store from whom the differential was originally purchased when making a claim for replacement or repair. All warranty claims submitted must include proof of purchase. Failure to provide proper documentation renders warranty null and void.

Exclusion from Warranty Coverage: The warranty does not apply outside of North America or to any Quaife ATB Differential which (a) has been improperly installed, installed in vehicles for which it was not designated, (b) has been modified or altered by the actual user or dealer or distributor, (c) was not imported or sold by Quaife America or through an authorized Quaife America dealer or distributor, or (d) was disassembled for any reason by the purchaser or his agent.

Quaife America's Obligation: Quaife America's obligation under this warranty is limited to replacement or repair of the defective or worn-out differential at its sole discretion. Quaife America has no obligation to bear any labor or other costs of return, removal and/or installation and will not be liable for any special, incidental, or consequential damages, including loss of use of the vehicle. Some states do not allow the exclusion of limited or incidental or consequential damages, so the above limitation may not apply to you.

Warranty Claim Procedures: Contact Quaife America at 32240-E Paseo Adelanto, San Juan Capistrano, CA 92675 tel (949) 240-4000 for specific instructions.

Rights of Purchaser: This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state.

 

Err, I didn't get a warranty form in the package with my Quaife ATB. Did I overlook something?

 

I didnt either. I called quaife and they said it should be included with my diff. The guy I spoke to took down my # and told me he would call me back. Well, Im still waiting

 

Mike,

any updates you can give us on the status for the replacements for the second batch?

thanks

 

Mike would it be possible if you could talk to quaife about our warranty forms? Maybe if you could have one scanned as a pdf so we can print/fill/mail it out? Quaife did not call me back, I guess you would have more luck being a distro for them

 

Quaife is beginning the necessary remachining on diffs that they have there in England on Monday. With any luck diffs will be on their way back to the USA by the end of the week.

Turns out that the first batch they used EDM (crazy electronic/laser thingy) to machine the drive splines. They later made a special broach to cut the splines for this round of diffs but the tolerances between the sample part they had there and the US cars we have here were off _just_ enough that they dont fit our cars.

I am dropping off a bunch of the bunk diffs at Quaife USA today (Friday) and I'll axe them what up with the warranty cards.

Thanks!

 

Thanks Mike!

 

The diffs shipped from England today. We expect to have them in our hands about this time next week fo shippment out to customers.

If anyone from the first batch needs a warranty card to mail in, send an e-mail to quaife@roadraceengineering.com requesting one and we'll send you one.

That's awesome news Mike!

 

I got the card and sent it out, I hope using the groupbuy's start date on the app's purchase date without be a problem.

 

Interested in purchasing a Quaife front LSD. When's the next batch/group buy happening?

 

There are a few available currently.

do you guys currently have any in stock? I am considering a quaife. Mike could you please pm me with a price shipped to medina,ohio 44256 for me!

Myself, being from a satellite shop with a machine shop capable of doing these types of super toleranced cuts, the EDM probably is used for part development / race applications. We're actually lucky to know they use the "best of the best" in machining tools, at least for development, and by doing the first batch of them with the EDM, they have an expectation for tolerances we'd probably not get elsewhere.

Thanks Mike for hooking up with Quaife!
