The only way on a GMT400 is wheel adaptors unless you get a 2500/3500 14 bolt rear axle with 8 lugs and go SAS up front. You can't swap 3/4 wheels hubs to a 1/2 ton and there are no 8 lug wheels hubs for a 1/2 ton.


:eek:

8 lug was on the HD trucks. You'd have to change a LOT of stuff.

Only gmt400 HD was a 10 lug truck and only offered as a cab and chassis without a bed.

Yes there is 8 lug wheel hubs for a 1/2 ton truck.

Well duh. I was talking about the 2500 / 3500 trucks. Sorry if they weren't called HD back then.

The old HD's had 10 lug in the back but 6 lug in the front, Did you know that :naughty:

Im not sure what the benefit would be going from a 6 lug to an 8 lug. Can you shed some light on the subject?

Is it really that hard to stop your 1/2 ton? I have no problems stopping mine. Buy some good break pads and rotors and you will be fine and save you a lot of hassle and time.

No one said no one made them, he was stating that he believed they never came from the factory that way.

Another option for those emergency situations would be to install a drag chute. That would help a lot.
