I will be installing icon 2.5 " leveling system and need some advice on some tire sizes. I will be installing 17 x 9 rims...can i run a 285/70r17 or do i need to go smaller? I don't want any rubbing at all and anyone have any advice on gas mileage difference when you change your tire size? Does anyone have any pics of their truck with the icons and rims and tires installed? Thanks

I have the DRs set at 2.5 or a little bit higher I'm not too sure. I had to cut part of the pinchweld and I still rub some on turns compressed running on 285/70/17 Revos. I would crank higher but my already-dead UBJ will be absolutely decapitated if you get my point.

Does anyone have any pics of what their truck looks like with 285/70r17? What kind of gas mileage should be expected? Will I need a differential drop kit when I install these coil overs?

Heck, if you just want to level your truck and don't really wheel it a lot I'll trade you my Bilstein 5100 lifting shocks for your Icons!!!

But really, your gas mileage may go down a bit, but it will be hard to properly calculate because your speedometer and odometer will be running slightly slower. You can fix this by getting a Truespeed. I just deal with it for now...

You could use the diff drop, but it probably isn't necessary. They don't do a whole lot and they prevent you from running a good skid plate unless it's modified. They do bring down the CV angle slightly....but it isn't much.

It is likely that your inner CV's will start to spit grease. This happens a lot. If they aren't torn, just take the stock clamp off and use two hose clamps per side (the screws on opposite ends to counterweight each other) and tighten them down. This holds the boot on slightly tighter. Search for the CV boot mod. This is what they are talking about.

I want a flashing image like those ads at the top of the screen on Yahoo etc, the ones like...

"YOU ARE TEH 100,000,000th PERSON TO ASK THIS QUESTION! THIS IS NOT A JOKE, YOU HAVE WON A NEW TOASTER OVEN!!1!"

Yeppers, definitely get after the search feature, anybody here can hook you up with instructions and keywords...we been lifting these trucks since 2000

.

Dunno if you picked 17s for any particular reason, but you can use 16s...gives you just a little more sidewall. 17s are better for handling, not as good for sneaking around on the rocks, at least not until you get in to 37"+ tires. Many of us ran 285/75/16 tires on 16x8 rims for years, I've been running 315/75/16 (roughly 35x12.5) on 16x8s for three or four years now.

It'll look really nice once it's done. I have plenty of photos but they're not up since we recycled the photo gallery

.

285/70/17 should fit, that's the largest you can go with that lift, and be aware it may still rub during turns in reverse and some turns with flex going forward. Just the nature of it...until you trim the wheel well, the largest tire which will fit at full compression in a turn is 265/75/16.

If you plan to go 4WD with this on anything relatively rough, you'll be much better off running the original rims with 255/85/16 tires...they'll fit better, less trimming required.

If you're going at speed across the desert, you can run the 33s...less need for compression in a turn.

Gas mileage on the highway stays about the same, in town it'll drop 1-2mpg depending on how you drive.

Make sure the truck is aligned using DJ's method. The high caster draws the tire away from the back of the wheel well.

I also have the Icon coilovers with 285/70 series BFG's. I hear a slight rubbing noise when the wheels are locked out while making a u-turn. Your mileage will go down, but I just bought a tru-speed unit.
