Ya, that 200lb gain makes me cringe. I can't do pro gears, street miles will kill it.

Two trucks have run 10's on them, rwd with Cummins power. Like Khaoskustoms stated, the D70u isn't a massive upgrade to the d60. It would definitely be a $$$ gamble
I'm shopping all options.
3.54 D80....$650 axle, 40 spline arb $1200. 3.31 gears are $460.
I could do a 35 spline setup and lincoln lock an open Carrier. Its hard to buy axles for a half assed setup though.
Next is a
3.42 14bolt....$175 axle, 40 spline arb is 1000. Parts are cheap, and they have a 3.21 gear set available for $285. Stock 30 spline carrier= ARB
Last for a reason is the 2011+ sterling 10.5 with factory elocker.
3.31 locker is 1200$, add the price of custom broached 40 spline spider gears 300$. After all that you have to trust stock ford parts to abuse....
