Yeeesh, sorry but here i go again, as for doing over 55 it is up to the individual and the ability of the driver, These trucks were never made to go that fast, your tires will wear very very fast at those speeds, your brakes will not want to stop u, if they get hot they will be worse, all the nuts and bolts will be coming loose on everything, the jack shafts will loosen up first probably, these are tactical vehicles, As for what Tm Americas says and does, He has a TON of off road experience to go with what he is doing, the novice needs to keep it simple. He knows how to handle a truck going wild off road and knows what to expect when trouble hits on the road, most do not by a long shot, i have been there sliding around corners in a tandem dump loaded on wet roads young and stupid, I have been around equipment and big trucks for ever, and I do not chance it. ...But I say do it for sure just my advise is keep it as much like it was designed and built to be driven, it will last longer and be more reliable also..These are great trucks........
To answer your question keep it at 52 and it will go forever and then take U into the woods too, change to many things and other parts will fail do to over use, like all vehicles, once u change one part for performance U will lose another type of performance, no truck in the world can have it all. These are awesome though, they are still taking a beating from guys who push em, but it comes at a price u have to work on your truck, or U will lose a shaft or brakes or just skid off the road when U find out that these big tires are off" road tires. They will get you farther into trouble than any of the others if U are not careful...
