I have:
295/75r22.5-fronts (brand new) f055 axle.
9.00-20-rears (good tread old tires came on axle) t-170 axle.
I'd have to check the leaves to see how many I have.
I have the 3-leaf auxiliary leaf pack 3inch wide, what is the rating on that?
As to the dump body mount, I dont believe it was mounted for full spring travel. I was thinking about getting lift blocks but that would raise my top heavy weight. But I dont take corners fast when I'm hauling... I try to avoid looking in the mirror at ppl riding my @$&.... but that's the only simple fix I can come up with becides removing the whole bed and adding 2 10-12ft pieces of steel channel/rectangle tube for a new "dump body frame/riser frame" or I could just torch off more of the bed side rails/edges for a deeper "fender flair" for clearance. But I'd rather avoid more torching to the truck.
Now to the quarry loading me up, I did one time get overloaded to 7.25 tons and I was leaning pretty hard cuz it wasnt centered perfectly. And it was really squatted. Dont remember if that was before the axle swap or not... I actually bottomed out a couple times and ripped off like 2 knobs of my tires grips on the side it was leaning to. And yes i was babying it the whole way home and it still was happening. But all in all the truck hauled it and dumped it fine. But I could hear my truck whispering to me not to do that again until I figure some things out!!! Lol.
