Reducing Body Roll assist (1 Viewer)

another as-yet unmentioned idea is to redesign the links....Mace mentioned roll center earlier, and that your present lift has just plain surpassed it's usefulness....a full redesign of the rear suspension (and perhaps the front panhard) might be a good solution.

initially move the rear axle center mount point about 3-4" higher and see what that does. Some time with the 4-lnk calculator should help too, deciding what link changes are effective.

wont you still need some sort of sway protection with coil overs?. or are you saying because your going to sawzall that you will go lower and it wont be as much of an issue?

If going lower, the front is easy to hack, for rear take a look here. http://store.summitracing.com/egnsearch.asp?N=700+4294861939+115+4294789118 I am pretty happy with my set up but if i ever go drastic this would be the route to lower 2 inches, 39's, coils..... someone needs to make some high clearance fiberglass fenders like this.... http://www.glassworksunlimited.com/shop/product.php?productid=81&cat=22&page=1

Saying that I will go lower b/c I'll be able to compensate by chopping the fenders. Front, is easy as is the relocation for coilover mounts (I'd like to have at least 18" travel).

The rear is a little more difficult b/c when you raise the wheel well you would hit the 2nd row rear seats and you also have to make room for the new shock mounts (which again minimum of 18" travel). Therefore I"ll either move the rear axle back about 6" or ditch the stocks seats and throw some Sparcos in or find some way to sawzall the rear seats.

I thought about fiber fenders(and hood with the vents), but given the high price and the fact that when they meet the rocks you need to kiss them goodbye...metal is a lot more forgivving and happy to see the blunt end of a mallot.

Time and money, when I have more of each I'll get to work....I am excepting donations...makes check payable to the "Sam needs CoilOvers" foundation

I have been thinking about the rear a ton lately. My rear shocks already sit mounted in cab right behind the middle row. Lookin at those summit tubs i think some surgery could be done and gain 3-4 inches of room. I am cool with losing the rear seats. I am looking into either a fuel cell or the aussie sub tank for the rear where the spare would have gone.... Once you dont need the stock tank you could fit a kick ass four link in there for sure...... also when you re-do the 4 link triangulate it, lose the panhard, and woody is right you could lower the roll over point......

your right, just do the front like slee did the front of the short bus and your set....

I would have to concur...

Is that front shock bottom mount lowered? If you don't mind, could you PM me a pic of that mount. Also, are the upper shock towers stock, stock modified, or custom?

As happy as I've been at the Cliffs, I was not happy at the Badlands last weekend. Way too tippy feeling. Perhaps I was a bit wobbly myself, or perhaps it was just the ground looks much further away. At the Cliffs the ground is usually just a few inches from your door.


Part of the problem with the pig is balance. The rear flexes like crazy, but the front does not. Longer shocks and better shackle angle are gonna happen soon.

Part, I think, is uncontrolled down travel in the rear. I'm gonna capture the spring tops and see what that does.

Roll center can be changed but It's a lot of work. RIght now it's at 26". I have no idea what that means. Raising my axle side uppers by 3 inches changes the Roll center to 30" and lowers the Roll angle from 5 to 3, but increases my Anti Squat from 91 to 122. I have no throttle related suspension issues now. I'd like to keep it that way.

On our 80 build we used a standard OME J lift with our 2" spacers, cut front fender wells, 4" lowered bump stops and 37x12.5x17 Radial Iroks. We have wheeled the piss out of the 80 and it extremely stable off camber. I would suggest lowering your 80 significantly if you want to reduce your body roll.

This the 80 or the 55?

Sold the 80.

It was a stable rig anyway.

This is on the 55.
