Question concerning spools

[Ed Wright]

Don ( Dewco) does many (most?) NHRA Pro Stock 3rd members. He has custom gear ratios, and other components for the 9 1/2" rears now used. I would not be afraid to use anything he sells. He knows his stuff.

I have worked on Mark Williams and Dewco third members and Dewco is nothing more than Mark Williams pieces.

Makes his price look even better. Don used to work for Richmond? He used to have a 9 1/2" gear set nobody else had. Mike Edwards used it at some tracks. Think it was a 5.08 or 5.10?
Lots of Comp guys use him too.

Not sure if he did....way before my time lol. I have worked for Pyle Bros. gor the last 5 years. 5.08 and 5.10 ratios in 9.5 are odd ball......but for the right price the manufacturer will make you any ratio you want in surplus lol. Just like ATI's 4.00 ratio for Top Dragster and top sportsmen guys who cannot make their mind up between 3.89 or 4.11......the only difference between the two is at most 200 rpm difference through the traps.

Before I lost my mind and started doing this again , I got in Mike's way for a while. Met Don during that time. I don't know if they run that much gear in Pro Stock now. Mike & Anderson were running 206/208 MPH back then, when about nobody else was.
The 9 1/2" stuff was originally made for fuel & funny cars, then the Pro Stock cars began to break 9" stuff. MW, of course, made the 9 1/2" cases, spools , etc.

You can get Moser and probably others to put in MW splines
on spool.....but not on their axles.
