im thinking about goin up to 40's on my truck, i have 37s now and they look small imo, i have 6+3 body and coilovers cranked 2 inches , will 40x15.50's on 20' hostages fit ? will they rub way to bad , and should i rase the rear with a 2inch leaf ? or will it be just fine, and im gonna go 4.88 gears will they be enough for 40's on 20's?

jus looking for sum advice , since therss a few ppl on here with that set up , thanks yall , any help greatly apprecitated

 

i'd go with a narrower 40, probably will have to trim a little as well depending on wheel and tire choice

edit: yes raise the rear up

 

If the picture in your sig is the way it sits now definitely raise the rear up some. With 40's in the back and the way it is now I see it bottoming out into the bottom of the bedsides all the time, so 2" would definitely help.

 

They should fit fine, but you should probably raise the rear up with either an add a leaf or lift shackles. dilloncawthon has 41x14.50s on his truck with a 6+3 and a leveling kit and I think the only problem he had was rubbing in the rear.

 

Do it but lift the *** end first, should look sweet.

 

yeah my next tire is going to be a 40x15.50. like atr04screw said, my main problem was the rear tires scrubbing. i think a 38in. tire is the biggest that can fit in the wheel well so that was the cause.

oh and if you haven't re-geared yet 4.88's will be perfect for that set up. i can hold the brake and when i hit the throttle my back tires almost immediatly start spinning.

the only thing you should watch is the width of the wheels. i know fuel makes some wide wheels with low backspacing so that could cause a problem.

 

Thanks for the info guys, sounds like 4.88 is plenty then, and for the wheels i have to find the backspacing out, if i dont do fuels im dooin rockstars

 

I'm going to run 40x14.5 km2s for my next set

 

Add-a-leaf the *** end. Front should be plenty clear (may have to trim lower bumper). I wouldn't go wider than a 40X13.50 without some kind of wheel spacer or a 10" wide wheel with at least -25 offset. Gears: 5.13's all the way--yukon makes them for the 9.75 rear end, you just have to grind that center pin down to get it by the ring gear---I did it on my 02 and it works like a champ. Expect a front end shimmy and quick wear on tie rods and ball joints!

 

and then how do you get the front done?

 

I didn't have any problems with that pin. If I remember right there was one part that I had to replace in a different order from removal but I don't remember what it was lol. Everyone makes 5.13's for the 8.8 front and rear but Yukon is the only one I found that makes them for the 9.75 rear.

 

if i remember correctly the problem with 5.13's was nobody made them for the front reverse cut and you had to get a set custom made.

 

I thought you were trying to sell this beast? haha

 

When I was in the market for 5.13's it seemed like almost everyone had them for the 8.8 IFS. I had to HUNT for the 9.75 R&P. Finally found them at Ron's Machine Shop on eBay from Yukon.

 

i been tryin to sell this thing for 2 yrs but no one wants to pay anything for it it kbb at 17500 , im askin 17 veryyyy very fair for how nice it is , evryone is cheap and useless and jerks me around , so i might as well go bigger lol
