12-bolt axle selection?

ss wannabee · 10-05-2013, 05:50 PM

Best way to combine lightness...with dependibility..on a 3500-lb car...283 and PG...
small tire too...might be foot-braked also...

1. 35-spline....gundrilled and lightened flanges....

2. 33-spline....with lightened flanges....

3. 33-spline...with no lightening...

Realize one or two companies will gundrill the 33 spline...but being a heavier car...
might not be the ticket? Figuring on an axle length of about 27/28 inches....(still
measuring tire and rim combos...and not set on final housing dimension yet.)

Thinking of finishing...with a lightweight steel spool...and housing ends...any favorites
on these? Ring gears have been lightened....

Wondering if the fact that the "hit" is less...(footbraking)...that I might be able to get
by with "less" axle...the 33?

Your input is appreciated!
