third member

[marty69212]

im getting ready to order a third member for my for 9inch. I don't know much about a ford 9 inch and need some help. like most. its going in a 69 Camaro with a quadralink, low geared t56 and a 600hp ls. im looking at a quick performance strange nodular case, with 370 gears and a true trac, don't now which pinion support or yolk to run. any help would be greatly appreciated. thanks !

I'd run a billet steel daytona pinion support and a billet steel 1350 yoke at that power level.

that's what I was leaning tword, thanks for the input. im running moser axles , will they be ok with a strange center section? also do you think that aluminum Yukon housing would be better?

[LS1-IROC]

The moser axles with the Strange center will be fine as long as the spline count is the same. I don't like aluminum center sections for street cars. The thermal expansion tends to create gear noise. If it's a track car where the weight really matters than yeah, aluminum is the way to go.

ok, sounds good, thanks for all your help!

is there a gasket that I should use between the third member and housing or should I just silicone it?

LOL..that's been a debate for years. I have always used a gasket with a very light coating of RTV on both sides. That usually worked for me until the last time I assembled my 9". It developed a slow drip from the gasket. Almost like it was weeping through the paper. I'm just getting ready to install my new center section and I think I am going to try it just with RTV this time. Also be sure and use the copper washers on the studs. They help keep any fluid from leaking past the threads.
