I know nothing about wheel spacers. Tried searching and failed.

I have a 4WD 2018 STX with 20 inch wheels, the only thing added is running boards. I DO NOT plan to lift it.

I would like my tires to stick out some. What would be a good size recommendation for the wheel spacers?

From what I can tell, they bolt right on, using the existing studs. Is that correct?

Sorry if this has been asked before, just want to avoid damaging my truck.

 

It's been asked a bazillion times and you mostly get answers saying don't do it, death trap, high speed wheel disconnects, get the right wheels etc.

I have 117k on my truck and nearly 100k has been with the bora wheel spacers. At the time I had 295/70/18 and wanted to be just outside the fenders and had Bora make me the thinnest they could, which were roughly 3/4" and I had to trim about 3/8" off the oem studs. Since then I've gone to a different time tire size and wish I had 1 1/4 now. Get a reputable brand, follow the install instructions and you'll be golden. Fyi, I took a near head on hit whereply my tire took the brunt, bent the frame a tad. Spacer held up and have about 30k mi on the same spacer. In theory thicker spacers will accelerate your ball joint wear, but so will higher offset wheels. Mine have a little play but nearly 120k on them.

I used a straight edge (4' level) to get an idea of how far I wanted to go, I also took off the wheel and started putting on 1/2" washers t better help me visualize it. I think I was able to get roughly 3/4" frim the washers and was only able to get about a 1thead or two of engagement from the lug nuts. Obviously if you try that, be smart and dont tighten the lug nut down and strip it.

 

I did a 2.25" ready lift level & 275/70/18 BFGs (stock was 275/65/18)
I added 1.25" spacers to push the tires out more.



Front tire looking down

Rear tire looking down


The level pulls the front in a little bit, that's why you see the difference front to back.
My tires are bigger than stock, so I'm thinking the 1.25" spacer might have you just about flush with the edge of the wheel well.

 

Thanks. I have never heard of the above regarding wheel spacers. I will have to do some research.

 

2" BORA spacers with stock wheels and tires on 2" front and 1" rear RC level kit.

 

Thats so odd that your rear sticks out way more than the front using the same size spacer. Most of what ive read is that the rear sinks in more by at least 1/4", my rears sink in more for sure

 

If you look at the geometry of the front suspension as the weight of the truck lifts up the control arms bend down causing the tires to move inboard.
The level is also moving the control arms down to achieve the lift, causing the difference seen in the pics.

 

Makes sense now. Thanks for the explanation, i was so baffled at first lol
