275/45/20 and 4/6 on a NBS

[Bugs]

I did a search on 4/6 and got 5 results. So obviously the search engine is hiccuping for me.

Anywho..... I know this is an old question, but i need to know some specifics....

What is the deal with putting 275/45/20's on a new body style with a 4/6 drop. (either DJM or belltech). Some say it fits, some say it dont. What do i need to do to make this combo work?

Im at 2/4 on an 01' SCSB now and and dying to go lower and get 20s. But without the GTII , i cant afford it as rubber doubles in price after those.

I have seen several trucks with this combo, but they havent replied to my mails for info, so i am here to ask.
ie: http://www.intensegravity.com/tx/kenneth.html

Why can some do it and some cant? Does the rim width make the difference? 8" vs 8.5" or what? Where do they rub for those who say it wont work.

Many have said the belltech drop takes away some of your turning radius, will this lower radius help against rubbing, as it wont allow you to go to the normal lock to lock of a stock suspension, thus protecting against rubbing?

Please help. I really want both, an am flexible on the rims, but need to know i can afford replacement rubber in the future.

I'm at a loss. I would take 20's over going lower, but want both.
Help a brotha get closer to the ground...

BTW, have any of you with SCSB 4/6 drops ever not been able to go somewhere because of the ground clearance? IE: underground parking garages? etc? Or is there always an angle to take which will allow you to go?

a NBS rolling 4-6 with 275/45/20s will be fine as long as your backspacing is correct. on a 20x8.5 you'll need 6.0 inches of BS ans on a 20x8 you'll need 5.5


also, stay away from BellTech on 99+ trucks.

[Bugs]

can i get confirmation that 20x8 with 5.5 BS will work?!

also, if 5.5bs will work on an 8" wheel, i will stick with DJM.
just have a better installer do the job this time

It's fine as long as your wheel backspacing is like mood_indigo stated. You will also need to reinstall your stock components (if you have hangers and shackles) for the rear to do a flip kit. If you dropped with springs up front, you need to either get 2" Lower control arms or get your stock springs and use 4" drop arms. :D

you dudes just made my day

and i have all my stock parts so im fine

The people who installed the first time must have tightened everything up in the hoist, as my truck has squeaked ever since. (fine all winter) but now its warming up, its doing it agian.

Bushings are not looking good. I can visually see where they are squeezed out of position

did you get it lubed afterwards??? also make sure everthing is torqued properly. both are causes of squeaky suspension.:D

[Bugs]

i figure if it squeaks, its just not low enough

new control arms and bushings willl fix all ;-)

thanks again..

well, 20x8.5 with 5.5 backspacing are on order, as are a set of 275/45/20s.

Now what exactly would i need to do to make a 4/6 work? Front and rear with no rubbing. *aside from different tires*.

You need 6" of Back Spacing on a 8.5" wheel to get 275/45-20's to work with the 4/6 drop, (not 5.5"). I think you'll have rubbing issues if you try to do this combo.

[Bugs]

i know all that. But 6" backspacing is expensive, and my sawsall and grinder are paid for.

I need to know WHERE the 20x8.5 with 5.5 rub when using 275/45, so that i can see if there is any trimming which can be done to make them NOT rub ;-)

[Lo Life]

I had to trim my rear fenders, and i have 6" of backspacing. I'm pretty sure theres not room for another .5" of trimming. The front, well I'm sure you don't want to cut there, but i'm also pretty sure it won't work. With 6" of backspacing it's close all around, no room for adjustment. I think that extra .5" is going to cause you a problem with 275/45-20's.
