drive shaft

A two piece drive shaft is stronger than a one piece, but is the mid carrier the weak link. how much abuse can a stock one take on 345 rear wheel hp and sticky tires.

Re: drive shaft

I have a bud that owns a 1960 Impala drag car. He is putting 850hp through that rig, and it has a stock 2 piece driveline with larger u-joint yokes welded on it. It has a factory GM carrier bearing in it. It has yet to fail wuith countless 1/4 mile passes on it.

Re: drive shaft

That depends on which carrier bearing you use. The light duty one that hangs from the top of the T/A crossmember or the HD one that sits on the bottom of the T/A crossmember. Of course this is assuming you are talking about a '60-'72 truck.

Re: drive shaft

Personally I would not run those driveshafts and carrier bearing behind anything other than a stock 250 I6. With the amount of HP you are putting down, I would definitely upgrade to the HD carrier bearing and driveshafts. Just my .02

The driveline I told you about might not even be compareable to a truck drivline. Just thought it was amazing myself that a relatively stock 2 piece with a carrier bearing was workin' that much HP and TQ.

Didn't wanna give out any false hope or bad info.
