feedback/opinions please.

do you think its ok to run 35inch tires on Dana 30 and AMC20 ?
(considering that I only ride sand, mud, and mountain trails. No rock crawling, and no heavy gas pedal)
 
Yo sure know how to ask the 'subjective' questions... :laugh:

My personal opinion is... You can run just about any tire and wheel combo on just about anything, it just depends on how much you want to keep fixing it! :D

IMHO, if you baby it, you would probably be OK for a while, but only if you upgraded the AMC20 to one piece axles and reinforce those tubes. The AMC20 is a pretty stout diff after you do that.

The Dana 30 would probably be OK for a while but I bet you go through a few axle u-joints... You could always put in HD U-Joints when they needed replacement but then your weak point jumps to a different section of the diff.

You just have to decide what is a good compromise for you. I mean, I have seen Dana 60's with broken hubs where it was though they would never break on the vehicle they were on. Nothing is finite...

You did say you have a SB chevy right? I bet you'll put your foot in it more then you think! :)
 
I can't say much for the Model 20, but my Dana 30 has stood up to me racing the CJ for a couple years ago. I run 35x12.50 Super Swamper tires.

I am going to build mine up with disc brakes, (maybe) Chromoly axles, HD joints, and a locker of some kind (probably an OX locker).
This is only because I moved to OK, and there is little Mud running here, but there is a LOT of rock crawling around here.
 
As was said about the AMC20 ; install 1 piece axles and reinforce the tubes.

Dana 30 will be fine as long as you don't put a locker in it. If you lock it then you'll need stronger axle shafts but you're still probably pushing the overall strength.
