Default Ford 9" vs. 9.5" 14 bolt from a strength perspective

Ok, you need one rear end that you can depend on isn't going to break at the track, 14 bolt or 9"? Specifically, 14 bolt with Trutrac LSD vs Strange pro nodular iron with S-trac. Which is more parasitic?

From a cost perspective, both are actually looking pretty similar....

Standard steel housing will do for me. Looks like got torque has the full bolt in housing with stock brakes. Get some 35 spline axles and a complete center section from Strange and I can assemble it all in my garage.

I think i remember reading the 9in is stronger due to pinion placement or an extra bearing. Something like that.


True/false?

9" is far superior, fact gears arent part of housing
Or having c clips

Availability of parts makes it desired

The biggest advantage to the 9" I see is that the center section is completely removable and can be serviced on a work bench. You can also have 2 separate center sections, one for street driving and one for track with a very aggressive gear set and spool

Like i asked i think the strength comes from the pinion placement or it has another bearing which adds to support. I could have swore i read that somewhere. I might be wrong thou.

Btw have you ever lifted. 9in center section? They are definitely on the heavy side. Like pop a ******** heavy.

I deadlift 3 plates pretty easily and am familiar with 4 plate deads. I'm not worried about a center section
