Wheel spacers and tire rub

slickman · August 4, 2017

Proper wheel spacers bolt on and do not shorten your wheel studs. The spacer itself has new wheel studs at full length. You want to make sure you get the Hub-Centric type from Bora or Supreme Suspensions. Avoid the "Disc type" that simply slip onto your existing studs. This does shorten your stud length and I assume could be dangerous over time. I run 1.5in Hub-Centric spacers from Supreme Suspensions with factory 18's. My wheels have the cut-outs that allow for the extra factory stud length. If your wheels do not have cutouts in the rear you will have to cut the nipples off your factory studs or simply replace them with shorter ones. Properly done I have never had any issues on several GM trucks. Wheel spacers are no different than changing the offset of your rims to get a wider stance. Spacers or offset wheels will put the exact additional strain on your suspension components.

I agree 100% I have the Supreme Suspensions 2 inch spacers, top quality.

There are a lot of impressive trucks on this forum with the high lifts and bro-dozer tires, but your truck is the perfect combination of looks, functionality and practicality. I checked out your gallery...good pics; those 285s look beefy and the DC looks like it's ready to put in work, rather than carry people around! I'm getting closer and closer to my next set of tires (36K+ on my current set), and when I do, I'm going with the KO2s and 1.5 spacers. I might also go Amps to try to look a little taller.

Any issues at all with the 285s kicked out that far?

Thanks for the comments! Yes my truck gets used as a truck. Mostly pulls my bass boat to tournaments and the hunting lease. I would never do anything to it that would hamper its pulling capabilities. The 285's did not rub at all without the 1.5in spacers. I have now noticed a slight rub in reverse at full turn only. It appears to be inside driver side nearest your feet. I think if you go with a 2.5 level you could avoid that slight rub. I did not want to go 2.5 or 3.0 since it does stiffen up the front suspension. I have ran 3.0 in the past and noticed quite a bit of "hop" or bounce when going over railroad tracks or dips on the tollway. Certainly a bit scary when you have a full load of gear and a boat in tow. I added a 30in LED light bar connected to a remote switch this afternoon. It fit perfectly on the Ranch Hand Grill Guard. If you are in the market I suggest looking at Arsenal Offroad. For the price you can't beat their products.

I've got the 2.5 in front and the taller block in the rear and will most likely go Fox and Cognito if/when I need ball joints because I hate the jarring that you mention. I run Firestone Ride Rite Air bags (no on-board compressor) that really make a difference when towing.

What's your mileage with those heavier BFGs? I'm getting 17ish when not towing with 31" Nitto G2s.

I just finished installing my 2 inch Supreme Suspension spacers, MUCH better looking. Wheels and tires are stock 17's with OEM size tries. No rubbing and the tires and rims fit like a glove in the opening from lock to lock.

I’m guessing you have the aluminum UCA’s? These stamped steel arms are creating such a headache. I can’t fit a 275-60/20 without rub

Man, am I glad I found this post! I also have a 2015 Silverado 1500 and have just added the 2" Supreme Suspensions spacers.

I've learned since that the nuts are of bad quality and stripped and I can no longer remove the spacers so I'm just going to keep running them and hope for the best.

I'm installing the 2.5" MotoFab Leveling kit tomorrow and was hoping to get some feedback before doing so. Now that your posts are almost 2 years old, I was curious how your setup was holding up?

Any feedback would be much appreciated!
