What rear end parts to buy?

NOSstang89 · 05-21-2001, 10:04 PM

The car broke a Moser forged axle last weekend at the track, so I might as well just upgrade the whole rear end so I don't break stuff back there anymore. What stuff will be happy with 5000 rpm launches with 400hp/500tq?
I was planning to upgrade to at least 31 spline axles, though I'd prefer 33 or 35. But that depends of what carrier I get... Does anyone make a strong differential that is streetable w/ 33 or 35 splines? If not, will 31's be ok? I also plan to get a rear end girdle kit and some C clip eliminators.

I need something that will be pretty good on the street, but strong enough for some hard launches. I also want something that is rebuildable so I don't have to keep buying new units when they wear out (eg., no Auburn or other gear type diffs...). Do such parts exist?

Thanks!!

yea 31 spline mosers, or strange axels with a good diff will be nearly industructable..the powertrax diff is good for 1,000hp if a cheap locker is what ur looking for

Strange 31 spline axels with c-clip elims, a auburn pro diff, MAC ta girdle. In my opinion this is a real good set up for a street strip car. P.S. I lauch between 5500-6000 rpm.

Be sure to get the "street" C-clip eliminators. They are a tapered bearing (take side loading) instead of a ball bearing type (do not take side loading).

Strange has this type and they are rebuildable, if you have a hydraulic press.

Theres no comparison to the bullet proof Detriot Locker, hell they run them with 800 hp Nascars, and they never break. They are avalibale for 28,31,33, and 35 spline axles I believe.
