D60, spring UNDER info,

[MarknessMonster]

I run both spring over and spring under on two trucks and there isn't much performance difference, but a lot of aesthetics. However, I run 36" and 39" tall tires on each respectively, so I'm gaining only about 1" of pumpkin clearance on the spring over. I do however notice a big difference in the grip performance between the two trucks, but that has to do with the skinny 36's and the fat 39's. I'd select a tall, skinny tire any day over a wide, fat one.

I suspect that if I were running a maximum sized tire, like 44's with the spring over truck, I'd achieve the performance benefit desired with such a modification. But I already feel, and likely look, like a big, immature, low self-esteemed idiot on the road with the 39's.

It doesn't help that the normal, off-the-shelf tall tire is usually a wide, fat balloon either...maybe it won't look so silly when I get the XZL's mounted.

Well with the S U A set up I'm THINKING less driveline, steering issues. The truck is tall enough as is for all but 'Hard Core Wheeling'. But the axle up grade, as has been stated before, is worth every cent, brake wise, wheel wise, and so and so. And as was said, you can go S O A later if you find you 'need' more room. Thanks, Guys.

If you'll ever consider selling it, the axle upgrade is a waste of money. Most folks buy them because they're unique, and not to "competition" off-road in them.

I can grind the shat out of these stockers and stop on a dime. I suppose that if I ever did some hardcore "Moab" rocking, then I might break something or require extra breaking.

I went SUA on my rig. I am also running an 8 lug dana 44. I was about to buy a 60 and then thought about the other 1k I would have to spend to get it up to snuff (the way I wanted it) and decided to spend $800 total on a 44. I plan to pull my boat and my buggy with the 715, as well as drive it daily and 3/4 ton is really all I need to accomplish that. I don't have any steering issues (high steer arms from sky man), and with disc brakes front and rear and the 3/4 ton J truck power MC it stops on a dime. I am running 34 11.50 tires on it too. It has the stock height which I like and performs at least as good driving wise as a 85 or so solid axle truck.

tngreenmachine, that info helps.
