You have the bora 1.75 right? How much do they run?

Yup, like $125 a set. As long as you get a quality spacer you’ll be fine

This tire size is very close to stock and I suspect the rubbing is a result of the level.  I wonder if switching to a smaller level kit would eliminate the rubbing?   A 1" or 1.5" level kit may  provi

BORA is the brand name of quality bolt on adapters: http://www.motorsport-tech.com/special/truck/chevy_s   I personally wouldn't use the Rough County brand spacers, they're lug centric,

Close to pulling the trigger on a set, the wheel tuck really bugs me.  I was unaware of the difference in track width but now that I know I can't un-see it.  

 

Gonna order 1.5" for the front and 1.25" for the back.   I shouldn't have any rub in the front with the stock suspension and 20" wheels when using the 1.5" spacer right?

 

78.1mm / 3.08" the proper centerbore for hubcentric?

Do you have a lift or level?

Someone correct me if I’m wrong but I thought the front stuck out .25” more then the rear on stock suspension?

Anyone know how much of the tip of the studs is not threaded? Also how much I can cut off and it not affect the threads/performance of the stud? Thanks in advance

ya i wrote the wrong thing.  I want a square setup.


I wasn’t questioning you I just didn’t want to screw it up myself because I’m thinking of doing something similar , only difference is I’m already flush with my fender with my offset in my wheel, I’m just trying to achieve a little more stance

I just ran out and removed 2 lugs of mine(one locking one oem).  There is 14mm between the top of the stud and the start of the first thread.

 

Funnily enough it took 14 turns to get the lug nut tight.  Therfore 14 threads of engagement is what is used stock.  I probably wouldn't go less than 10. (this is assuming stock wheels your aftermarket may be different thickness which will change the number)

 

What is the torque spec for the lugnuts?

I believe it’s 150 ft lbs. but you got me thinking, even tho it takes 14 turns doesn’t mean that you need all 14 to “hold” the wheel on, so let’s say mine met the wheel at 10 turns to tighten, does that mean that the threads before that are not really needed to secure the wheel properly? Or what am I thinking is wrong?

how many threads of engagement is what is important and is what provides the strength needed.  I'm not quite sure what your asking.  There are unused thread at both the back of the stud(the wheel thickness) and the back of the lugnut(the part where the unthreaded stud resides once tightened).  That 14mm of unthreaded stud is useless and you can cut it off with no ill effects.  adding spacers essentially increases the thickness of the wheel and therefore more threads are covered and cant be used.

So take for example the lugs that come with bora wheel spacers are only approximately 1/2” long. So in theory if I have at least let’s say 3/4 of thread to use then the lug should be able to tighten to specs no problem. So if there is any more then “needed” then I could cut this off and it could still work? Or is there a reason that this could be in safe?

You can cut off any threads that come out the backside of the tightened open faced nut without affecting the strength.

 

 

The only real safety issues regarding spacers is

 

1. slip on spacers (the ones that dont have its own studs) these spacers essentially increase the thickness of the wheels and less threads get engaged.

 

2.  using adapter style spacers that are too thin.  When this style of spacer is too thin the factory lug nuts stick out past the face of the spacer and prevents the wheel from sitting flush against the face of the spacer.  This is the scenario when you would have to cut the stud so its behind the face of the adapter or the wheels need pockets on the backside between the mounting holes to accommodate the protruding studs.

 

3. Spacer out of balance.  The spacer is part of the rotating assembly along with the rims+tires.  If the spacers arent balanced you will have the same symptoms as your tires  being out of balance.  The only solution to this is to buy quality spacers.

 

4. Wrong hubcentric size.  If the adapter hub size is larger than the wheel it will prevent the wheel from sitting flush this is a very unsafe scenario.  If the adapter hub size is smaller you can get a hub ring to make up for the size difference.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
