BORA is the brand name of quality bolt on adapters:

I personally wouldn't use the Rough County brand spacers, they're lug centric, not hubcentric.  I would go with a set specifically designed for our trucks.  I think I paid $50 for my pair, which isn't cheap, but I had no vibration or balancing issues. 
Mine are from RC, 2" spacers. No issues either. Have had them installed for nearly 2 years now.33fa05020c3f6707bdbe86e02b3c0309.jpg619d5f070c5ff54ddf2c09d5f50790a0.jpg

I meant the RC slip on spacers, not the bolt on adapters.

If you have the factory Snowflake wheels, you can run a 1" BORA adapter type spacer, and not have to trim your studs.  Personally I wouldn't go bigger than a 1/4" with slip on spacers, you want to make sure you're getting plenty of thread engagement. 

Only a 1” spacer?  I would have guessed at least 1 1/4” or 1 1/2” would be needed. I have the factory 20” Denali Wheel which is different that the regular Snowflake wheel.  I also haven’t taken the time yet to remove a wheel and check the depth of the holes in the back.

IDK about other wheels, but the snowflake have enough relief to run a 1" adapter.

I ran a 1/4" spacer on the front of my truck when I ran factory wheels with 305s, and it helped eliminate a lot of the rub.  With a 285 or 295 I'm sure that 1/4" would get rid of all the rub.  They're nice custom hubcentric pieces, I don't need them anymore since I went aftermarket wheels and control arms, let me know if someone is interested.

I would be!  Do they still allow the oem wheel to sit on a hub ring? Or studs only?

Yup, the wheel remains hubcentric with the 1/4" spacer.  Message me if you're serious, and we can set something up.

For the record, I removed a wheel & measured the depth of the cavities in the back of my 20” Denali wheels...  a 1” spacer wouldn’t work for me.  The studs are 1 3/4” long & the depth of the cavity is only 1 5/8”.  A 1” spacer would be at least 1/8” short of what’s needed to work.  Here’s a pic of what the back of my wheels look like...   I decided to go with 1 1/4” spacers & they’re exactly what I was looking for.

Pulled the trigger on some 1 1/4” spacers for my truck.  Install took about 1.5 hours as I was taking my time, did test fitting at each wheel, made sure everything was clean, then made sure all were installed correctly.  Here’s a pic of how she looks...

I have a little experience with slip on spacers as well as thicker bolt on spacers with studs.  I ran several different sizes and styles of slip on spacers on my Camaro.  I had some cheap cast spacers for a while.  They suck.  They do not hold torque well at all.  The billet machined spacers are much better and are more stable.  Just make sure you still have enough thread engagement, minimum is 1.5 x stud diameter.  If you are short of this, ARP makes some nice longer studs.

 

Same goes for the bolt on spacers, billet machined are way better than cast.   Make sure they have quality studs and nuts.

 

"Flame suit on". I have found zero difference in performance between hub and lug centric spacers.  Not in drivability, steering shake, perceived wheel shake or bearing life.  The way I see it, the lugs MUST help center the wheel anyway with tapered (acorn) lug nuts other wise tightening them down would try to split the wheel if one or more were off center.  I think hub centric is nothing more than an assembly aid to help the lugs center up on the assembly line to speed things up.  "Flame suit off". Just my opinion.

Are your tires stock 275/55r20 size?

 

With a 1" spacer you need 3/4" deep pockets, correct?  I'll have to measure my wheels.  I kind of like not destroying my feet ders with rock chips though...hmmmm

No, slightly bigger with 285/55r20 which are about 3/4” taller & 1/2” wider than 275/55r20’s.  On the truck my BFGs are nearly an inch taller than the stock Goodyear SRAs it came with.  

 

With a 1” spacer, yes you’d need a wheel with 3/4” deep pockets or more.  The other option would be to trim the end of the stud some.  There is room to do that as there’s about 1/2” of stud length that’s not threaded or used.

    • 287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.      
    • Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣
    • My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!
    • The Allison 10 speed torque converter doesn't "lock up" like the previous transmissions. It has 4 operational modes; open, slip, transition from open to slip; transition from slip to open. I have an Edge CTS3 monitor and I monitor transmission torque converter slip. Step on the gas and you get a little slip. Take your foot off the gas and you get a little negative slip. I have not found a way to display the torque converter mode beyond that. My Edge CTS3 also displays something that our trucks should already display, the current gear. I also monitor throttle body position and engine load. If I see the engine load getting too high, I'll manually drop a gear.
    • Nice result. Your filter is working well  I'd have like to have seen the acid number for this sample. Curious type that I am.
