I have a '99 superduty, 4x2, 158" wheelbase, that I have removed the box from and installed a custom sevice body.

I weighed the rear axle today and it has 5,280 lbs. on it, it is rated for 5, 530 lbs.

What do you think is my best solution to increase load capacity. I would like to not stiffen the ride if possible and maybe raise the rear end and inch or three.

Thanks,

Randy

 

P.S the superduty is an f250.

 

get an add-a-leaf...it wont stiffen the ride too much and i dont know how much it'll increase load, but it'll lift the back at least an inch...different leafs give different amount of lifts and increase in load...i know i saw a f250 with an 8" lift one time and some 38s...and that thing had a ****load of leafsprings...several more than stock...i know he could carry a lot in the bed...just a thought...

 

add-a-leaf's or you could try those adjustable overload springs

 

I don't think you can do anything to increase the load capacity of your axle. You can just make modifcations to the springs that affect capacity and/or height. Maybe a good spring shop can help you out.

 

Check with the guys that installed the bed. I'm sure you're not the first one who's had one installed. To be honest, regardless of what the axle is rated at, I don't think you'll have any problems, if you were going to, they probably wouldn't make the utility beds that heavy. : )

Anyway, about the only solution would be to install a heavier duty axle, and I don't know what your options are there. After all, the question you're asking is not about the springs, however that doesn't mean that an add-a-leaf isn't in order.
