Default how much will this 9" handle

Moser housing
Moser 28 spline axles
original ford non-nodular center from Ford Grenada(spelling)
new 4.10 gear
tru-trac posi


now how much power and abuse will this thing handle ? i know the 28 spline axles and non-nodular center are weak spots, but will it handle 500 hp launches on slicks? is it worth picking up for $1300

IMO mid to low 11's with a stock case so your 500 hp would push the caps after a few passes.

Well I have that setup with Moser 31 spline axles and once I started running mid 11's I have killed 3 (in less than a year) 9" center sections at the back pinion bearing.

I have just over 400 rwhp and it can't handle it. If you launch a 6 speed car hard enough to pull a low 1.6/ high 1.5 60ft they are VERY HARD on a stock case. Atleast get a good pinion support. I have a spool (mine is a track only car), Strange case and a good pinion support on the way.
