SAS question:

[ShadowRejects]

when dropping a Dana 60 in the front of a gmt400, is it nessisary to put a different axle, such as a gm 3/4 14 bolt in the rear as well? or can you leave the rear axle stock?. i know it depends on the gears, but im curious

well ive never seen a dana 60 in a 6 lug so you'd have 8 lug in the front and 6 in the rear... and if your going to go through all the work of putting a d60 in the front you mind as well match it up with a 14 bolt ff in the rear. or if you want to stay 6 lug then find a dana 44 or 10 bolt that is six lug for the front and use your same rear or find a 14 sf rear thats six lug. the options are endless, all depends on what you want to do with it and the kind of money and work you are will to do.

Look at my build thread as well. I did a D44 up front and kept everything 6-lug.

You can leave whatever you want out back, but most go with a 14 bolt.

leaving the rear stock wont mess with my truck and let it skip in 4wd, will it?

As long as the gear ratios are the same you are fine. However, bigger tires will eat 10 bolts for lunch.
