Hey there I am yet another newbie from Alberta. I came to this group in search of info. I own 3 73-87's 2 are crew cab dually's. I am currently building the 88 K30, I have built a 460CID (Chev of course) gone through the Sm465 and so on and so on. Where my problem lies is in figuring out lift size and what others have been able to run...as far as tires go. I am a HD mechanic and my shop gets a smoking deal on Nitto tires once a year so i just ordered 8 40X13.50X17's mud grapplers and 6 aluminum ultra 17's including 2 for spares and 2 steel 17's. Can anyone give me some guide lines as to what (in your opinion) size lift will be needed to tuck 40's. Body mods obviously will be necessary as will wheel spacers and such, I am more interested in finding out size, 8"-10"-12".

at least 8"

How wide are your wheels? How do you wheel? hardcore off the beaten path or shuttling between gas stations? How much are you prepared to spend? If it were me, I would go with a 3" body lift and cutout flares if your running it on the street, or 4" front springs, a 4" shackle flip for the rear and the Flares for serious trail use.

Welcome from California, my brother-in-law had 40" on an 82 back in the day, he had a 12" lift with no rubbing.

Hey thanks for the info, Now how about i give you all a bit more aswell. I have 17X7 wheels but my tires have a sudgested wheel width or 8.5-10" wheels. I have no doubt the tires will mount but the only reason for me sticking with 7 wide is due to dually wheels only being offered in minimal widths. Now on to my wheeling, I obviously will be going from station to station due to the 460/sm465/np205, 4:11's and 40's ha ha. Now if there were to be a river and or a few rock obsticles in the way........ Thats all me. ;D Last but not least my budget on the lift i would like to stay under 3500 before drive line work. I would also like to divorce the 205 from the 465 for as cheap as possible.
bake74 your in laws 82.... was it a dually?
thanx a bunch guys

I'm pretty sure you're going to have issues running that wide of a tire on 7" wide rims. Some of the other guys may chime in, but to my knowledge I would say 10" rim minimum. As far as lift, if it's going to be mostly on road an 8" to 10" lift will work fine with 40's.

That's what my gut tells me too.
If it all works out as planned, that thing will be a beast, so put up some pics.

I work at a Kal-Tire doing all the heavy duty shoot but our store is both commercial and passanger tires as well. I am expecting problems on the mounting side of things and I also know this will be a all bars affair and no machine. But like we all know with enough effort anything can happen...lol I hope. Now is there anyone here that has gone quite so big on a dually or is everyone running dually's stuck on 37's? thanks again

I am currently building the 88 K30, I have built a 460CID (Chev of course)
It would be a V30 as in 1987 this body style changed the designation of C/K to R/V and in 1988 the new bosy style resumed the C/K series designation. You probably have a 461CID if it's a bored 454 which will help you out without having to say 460 Chevy and not resemble a Ford :P Post pix!
-
Here's some pix of the starting product and then of the truck torn apart in the shop beside my '90 crewly 2wd half way done
oh and i guess it is really a V30 ???
-
The Engine is a .030 over bore 454 with a cam and a few other little goodies as well. I have been told everything from 460ci-462ci lol so somewhere in there
-
I think trying to run two 13.5" wide tires side by side in the rear is going to stick way the heck out. Even if you could get them to fit on narrow rims. I've seen 38" military tires on a dually before, but they were only 11" wide on a 16" rim. They still looked mean though. ;)
-
I am going for the street legal until pulled over sorta deal lol equipment violations don't hurt the license. And the insides will get real close with articulation I am sure.
-
Welcome from NH. Make sure those dual rear tires aren't so close they will rub. Good luck and post up some pics of the tire/wheel set up.

OK so its been a few days now with still little to no definitive answers on my question about lift size and how to accomplish the 40" feat. I knew this was a unordinary scenario on a dually, But someone has to have some guide lines for me to follow before i just order 16" of lift to be sure they tuck lol. I have a feeling it will be 10-14" required. If you could get back to me with how big and how you would accomplish it it would be great. Thanks for you help in advance.
-
Worst case scenario your a few inches low and you have to put the cut out flares on. Your choice on lift, some like tucked look others like their tires to never enter the wheel well.
-
By tucked I meant crammed in under her lol. My main thoughts on lift are, should I just go for 12" all springs and leave the shackle flips for a just in case I come up a little low? Or would you all say that the flips would be important. Also I have heard mixed reviews on certain brands of springs...... any truth? I Have talked to a guy at ORD and I know this can all be possible for my budget but I really just need to decide on a "kit" to assamble.

So my new wheels came in today!! Well all but the steelies. I will upload some pix later on tonight. I also got a call from our warehouse in which we get our nitto tires,"hey sorry man but we only have 4 of the 40 13.50 17's that you had ordered 8 of...... And it will be a while before we see more as they are back ordered with no ETA" So with the ultimate dilemma on my hands I did what any respectable man would do and ordered 8 37 13.50 17's and will have them by Friday! So looks like I will be barring some rubber on the rims Saturday afternoon ;-) Just thought I'd give a little update and see if anyone here now has any better suggestions on lift size as now I only need to have enough room for 37'S. Thanks in advance

I have 7" of lift and 37's clear just fine. If you went with 8" it would be perfect. Doing a 52" spring swap in the front with the correct shackles & a shackle flip in the rear with 4" lift springs would be a sweet setup. ORD sells everything you would need.
-
thank you so much.
-
I wanted to add, you need a kit to run 52" springs up front. These guy's should have everything you need: http://diy4x.com/
-
It took a while but here are the pix as prommised.
-
K20 wolf: To do the 52" front would you say that the 7.25" shackles are the ones to go with? And What would that end up giving? 8"+/-

If they are new springs you should get around 6" of lift (With the shackles), then add a zero rate and you should be right on the money. http://www.offroaddesign.com/catalog/Zero%20Rates.htm

Sounds good, my last worry would be if i wanted to go to the 40's in fall when i get the next sale........ do you think 8 would still be sufficient without needing so much zip cutting? or would you just go bigger right off the bat?

I would not go bigger than 8", you will have too high of a center of gravity. There are literally tons of guys running 40's with less lift than that. Taller is not better.
