i have a 14 bolt out of a heavy half (2500) 6 lug. i want to take another 14 bolt out of anything else with 3.73s i figure its gona be out of a 2500 8 lug. could i take the 6 lug shafts and replace the 8 lug shafts? would it be that easy?

-DONT TELL ME TO UPGRADE THE FRONT TO 8 LUG, its going in a 1500 tahoe the axle was free and the old one is trash so i figured to go big.

Not likely. If I recall the 6 lugs were semi float and the 8 lugs are full float. Axle shafts should be different.

I am not 100% sure on this, there may be an oddball full float 6 lug out there, but none that I am aware of.

the heavy half would be a 9.5" semi-float 14 bolt. staying with the 9.5", axle shafts will swap...the 10.5" full-float is a different axle all together. Hit up youtube for a diy video to make sure you have the process down pat before you start.

The GM 9.5 (what some refer to as the semi-float 14 bolt) uses 33 spline C-clip shafts.

The GM14T (the full floater Corporate 14 Bolt) is 30 spline in stock form.

There is nothing similar between the two axles other than they share the same number of cover bolts.

What's wrong with the 9.5" 6 lug? Different gearing than front diff?
