So... How much does a 14 bolt FF weigh?

[divorced]

I know this has been mildly debated before. My guess is 420 pounds for one that is complete with the big drums, 3.73 gears, gear oil, and a Gov-Loc.

The highly scientific method I used was - Weigh empty truck on a scale about 3 miles from the shop. Drive back to the shop and load the 14 bolt. Drive back to the scale and weigh the loaded truck. Drive back to the shop and unload the axle and disassemble it to sell the parts. The weights were 5380 loaded and 4960 empty.

Too much

Ya, especially if you're a little scrawny sh!t like me! I don't move the axle... it moves me.

So besides the obvious, what is the advantage of a ff compared to a sf?

 

[jekbrown]

Depends on what "the obvious" is I guess. Its a stronger axle, thats pretty much all that matters.

when my 14b was shipped, it weighed in at 415 lbs on 2 half pallets...so ill guess prob 390ish overall. It had full disc brakes, gears, detroit...everything was ready to go cept brake lines (which weigh all of a pound) and spring perches and shock tabs.

One of the advantages of the FF is that if you are ever to break an axle the wheel ( and part of an axle shaft ) wont come out.
FF has 10.5 inch ring gear
SF has 9.5 inch.

Both are very strong... FF is stronger though.

SF has more clearance and weighs less. It's all in what you want.
