He does have a KTRE housing that'll fit an F-body, but as stated, is about $3Gs (although that's not really that bad for the quality). You could rest assured that if it came from them, you'd have a VERY nice rear...

reason me asking about this cause a guy I work with say's his brother works for them and he has seen the plant and all. he talks highly about M. W. products and says I should get rear end from them. I'll call and see what happens.
thanks guys.
just curious why nobody mentions them. all I read about is Moser/Currie/Strange/DTS. now I know about M. W. IHRA, NHRA, Nascar use them, so they must be strong as hell.

you mentioned
'Just curious why nobody mentions them. all I read about is Moser/Currie/Strange/DTS. now I know about M. W. IHRA, NHRA, Nascar use them, so they must be strong as hell'

Buying Mark Williams is equivalent to buying a Mercedes. Very high end stuff with probably the highest resale value. Any bracket car with money in it will have MW or strange stuff in it. You'll find the Currie/DTS stuff in Hot Rod magazine while the Moser/Strange/MW stuff can be found in National Dragster and Drag Review or any other hardcore racing magazine that you can't buy off the magazine rack.

High quality rears, but some of the stuff wont work with other brands - friend broke a mark williams spool & he also had mark williams axles & had to replace with another williams spool cause the splines are made just a little different so his axles would not have worked with another brand of spool ) that was right from the people at moser - where he called to buy a spool 1st

I mention them all the time.

As previously stated, MW is the considered shizzy. Right along with Chrisman and SummersBrothers. They are not 'cheap' by any means as stated around here.... mainly because most around here have not had a requirement for parts of this nature. Nor are they a 'barney bolt on' company.... which is good reason why they dont advertise in this medium. You have been slammed with advertising and blinded by cheap pricing, from other companies, which make it seem what they have to offer to be affordable..... but in reality, isnt even on the same playing field.

Some might cough when they see the $3k price tag for a 12bolt.... but you wont be hearing about gear noise and set up issues with their product either. You are paying for years of research and development in so many types of racing and the quality that goes hand in hand with their demands.

MW, Chrisman and SummmerBrothers are the "Katech" of differentials. You get what you pay for.

The resaon that some MW parts dont work with other manufacturers product lines is that MW has specifically engineered their components to their own criteria. The reason that your friend had to use another MW spool is due to the fact that the 'pressure angle' of the axle spline on the axles are specific with the pressure angle of the internal spines of the spool itself. You can not mix and match or even more serious failures will result.

I have used MW stuff for years and have had many custom and propritary components and axle shafts, not to mention other various parts made by them. If you have been in and/or around this industry long enough, its a household name..... right next to Chrisman, Dynatrac and SummersBrothers.

If your co-worker can get you the homie hook up.... I'd be all over it.

A list-o-links of the big dogs:

Mark Williams

Chrisman

Dynatrac

Tom's

Summersbrothers, D.Araki, PPI, Hughes, myself and some of the others dont advertise... they are word of mouth and more of industry special shops. You basically have to be refered for their services.

It's how it is assembled ..... and what else is done to the stock units that makes the big difference. Anyone can take a pile of parts and assemble them... its a whole differnt subject when you know what else to do with the rest of the parts to make them live longer.

I dont know of any internal differential part that I do not modify before its final assembly.

M/W parts are the best of the best hands down. Their tech/sales guys are very smart and precise. I have ordered and installed many of their products and their 35 spline axles and spools will not work with anyone else's parts. They change the pressure angle on the splines to work with their own parts only. If your looking to build a $3,000.00 axle give us a call we can build it with anyone's parts. Just specify when ordering and we'll beat anyone's price.

O.K. I'm realy thinking hard about purchasing MW diff. thanks for the input guys. I know these are 3k rear ends but, I want quality. not that others are not but, I want them to hold on the strip at luanch's of 5k or so and I'm sure most others can too but I know MW took there detailed time and research putting these things together at close tolerance, plus if I get MW Diff at a 2500.00 I'm ahead allready. guess depends what ur looking for and comfortable with.
