37" Radial Iroks, 6" Slee...results wheeling

[GXO]

Some folks have asked to post results with my lift/tire combo.

I went up to Tellico yesterday for the river cleanup and went up 5, 6, 4, and part of 3 hauling trash and following Tellico Rob's stinky diesel 40 with a trailer attached to it.

We got a TON of trash and met a load of Jeep, Trout, and Hiking folks...the ATV "cockroaches" scurried all over and didn't do a thing

Anyway, I got to test the new Iroks, lift, etc. and I was very impressed. I aired down to 17 lbs on all 4 and the bulge was not nearly as bad as the MTRs at the same pressure. I was able to idle, and I mean idle over most things in the way. The Iroks gripped like no other tire I have run (ATs, MTs, Swampers, etc). I spun a tire 3 times all day. I rubbed the diff in the front 1 time, and never used my sliders except to pivot on a rock while I was checking my clearance

Now, the fitment is amazing. I rubbed VERY slightly on the custom exhaust run, but no other rubbing aside from a mild touch on the frame in the rear on one side (I still have to adjust the panhards post lift).

I have some detailed pics from the ride, but they are on my sister's camera. Once I get them from her I will update this thread with some poser shots

So, conclusion:

If you wheel in the eastern and midwestern US, have a truck that you drive to the trail, and want the maximum traction, carcass height, and toughness in a really agressive offroad tire...Iroks are the bee's knees!

UPDATE:

Here are some pics:

Running Gear:

Rocks! Most take a line around this...

Flex n Stuff:

I only did one wheel stand all day, very controlled and stable, and never lifted a tire otherwise...great result.

Tire cost?

They were *gasp* $1800 from 4wheel parts for 5 with no balancing, just mounting, and the no questions asked replacement warranty. I used $100 in dyna beads to balance the tires vs. paying for it and having to go back a lot. I don't DD my rig so these seemed like a good choice. Highway travel got a bit shakey at 65+ but otherwise it was very tolerable.

Very I mean VERY impressive.

Damn I want that lift and I want IROKS too.

Imagine that toys one would possess if not married.

 

[GXO]

Thanks.

What I found most impressive was the stability. I was through those trails not too long ago with J springs and I felt a LOT safer and more upright. I think the pictures show that as well...very little lean. Those Slee springs certainly hold up!

 

[Wrench]

So your telling me you felt more stable higher up? Higher CG?

 

[GXO]

Correct. The COG is higher for sure, but the spring rate makes the body roll much less. J springs are too soft for most built and armored trucks like mine, and it was SCARY to wheel like that. It felt like the body unhinged and tried to fall off the frame when I got off camber.

These springs level the body nicely in those same situations. Look at the level of the body in those pics, I think they speak for themselves.

That said, I am also very careful in how I wheel and if there is a steep side slope I take a different approach for tippy safety

 

[Wrench]

Don't like off camber stuff huh? LOL! But those pic don't look to tough. I would like to see you on more hardcore stuff that throw the body around into trees and rocks to get a better idea.

 

[GXO]

I will have pics in the hard stuff once I get the chromoly in all four corners

Why does this seem counter-intuitive? Seems softer springs would allow more flex, and allow the body to stay more level.

You're still on 2" bumpstop drops right?

Not to bust your hump or anything, cause I like the truck, and I like the pics, but you're not fully stuffed there, right? I mean, I have 2" bumpstop spacers on the front, and with only 315's, I stick more tire in the fender than that. Just wondering if you'd rub if you got it bottomed out on the bumpstop.

 

[GXO]

I was cleaning up Tellico and still have to swap in longfields and fix the rear axle. Most places in Tellico for full flex don't appreciate my current issues .

That was the best I could get at the time. I promise to do better when I get everything finished.

Oh, I don't have any bumpstop drops in right now...they get delivered with the new slee arms sometime in the next week or two.

Actually, the 6" springs hold the weight better, that's all. Not a matter of flex.

I am not saying my springs are more or less flexy than Js. In fact, they are about the same. The issue is the spring rate. Js hold less weight and they compress and extend too easily for the weight of the 80 series body, especially with armor. So, if you take a J sprung truck and push on the side, it sways in the wind. Do that to mine and it will sway over, return, and stop...no cycling in the springs...they recover instantly. That leads to more stability on the trail since you aren't cycling all over the place on Js. Been there, done that.

Oh, and then there is the road thing...WOWZA! 6" Slee springs are 100% better on the road than Js. They just are, no question.

 

[peepers]

those tires are gorgeous. i wish they made a set of radials!

 

[GXO]

Those are radials

Sounds like you were undershocked with J's.

 

[GXO]

Either way, I am happy with what I have now

 

[alkaline747trio]

Hey dan, I got me some 6" front springs now...and mine sits nice and level with the rear Js. BTW, my XL's are coming in the end of this week or the beginning of next.

Those IROKs do look sick on there, now I'm wondering if I should go with 37's myself or stick with the plan of 38" Boggers. The black rims fit right in too.

I still don't get how the 6" coils are better than the J's they both have the same spring rate. Just one is taller. The J's should be more stable since the COG is lower. There is no way a taller truck is more stable that a lower one. It goes against the laws of physics.

 

[alkaline747trio]

J's and Slee are NOT the same spring rate, the Slees are much firmer. It is more stable due to less body motion, if the body rocks less side to side then it is less tippy, although the maximum angle before tipping has been lessened (or increased depending on how you look at it), it takes more effort to get there.
