Wheel spacers; 1", 1.25 or 1.5"?

Planning for my lift to fit 35x12.5 on stock rims. I will be putting springs from JKUR on as well for lift (hope to gain 1.75-2"). The Jeep is a 2 door Sport, 2012. As I want to use the stock rims I'm thinking about spacers, but there are some options. Looks like most people choose 1.5".

So what are people's opinions about using just 1" or 1.25"? I would like the tires to stick out as little as possible.

Whatever spidertrax is offering will be fine. They're the industry leader, and I'd stick with them.

You need to check recommended wheel size for that tire. I think 12.5" is too wide for a factory wheel. There may not be enough rim to hold it. I think 11-11.5" is about as wide as you can safely go on any of the factory wheels. The tire manufactures specs will give you min/max wheel width.

The reason for spacers is to make room between the wheel center and the hub in order to fit wider tires under your jeep without the tires rubbing on the tub or control arms, or the frame. Measure how much clearance you have with your existing tires and it will dictate how much more room you need in order to fit your specific tire desires.

Another concern is the length of the studs in your hub. If you put on a 1" spacer, then 1/2" of the studs will "stick out" of the spacer. You will have to either cut off then end of the studs, or replace them with shorter studs.

I'll have some pics for you this week. I'm mounting Pro Comp Xterrain 35x12.5/17LT's on my stock JK wheels. Actually have one mounted already and they fit just fine. I'm like you and didn't want them sticking out to far beyond the stock fenders. I went with Spidertrax 1.5" spacers, which should be here in a couple days. I will post some pics as soon as she is setup.
Oh, also just finished my lift. Rough Country 2.5" springs and shocks

i was told by TeraFlex that 1.25" is the smallest spacers you can put on a JK without hving to mess with the stock studs...
I WANT spacers , don't really NEED them... so i wanted to find somethign smaller then 1.5" I found the TeraFles 1.25"... contacted them and they set me gave me the low down.. I am NOT looking to change or grind the studs on my brand new JK

The reason people use 1.5" is the studs on your hub. They are 1.25" in the front and 1.3" on the rear (If I remember right, might be the other way around). 1" spacer will not cover the stock studs and you can't put wheels on them. If you use 1.25" that are really 1.25" then more then likely the stock studs on the rear will stick out just barely enough to cause issue. Some people will put the wheel on anyways but that isn't safe and one of the reason for the bad name of wheel spacer. Installing improperly. You can grind down the stock studs a little on the ones that are a tad long if you want but it is just safer and better to get the 1.5" and not worry about it.

Just finished her up tonight. Rough Country 2.5", coil/shock lift. 35x12.5/17 Pro Comp with 1.5" SpiderTrax. After 50 miles, I'll be pulling the wheels off and checking torque. At that time, I'm painting the rims black......
FYI- from the bottom of the license plate to the ground is 25"

just an FYI to anyone interested....according to TeraFlex and Q-Tec the TeraFlex 1.25" spaces (Tera #1055000) will bolt right up to a 2013 JK, with no stud grinding required.

There is a youtube video by teraflex that might need updating



@3:20

They claim any 1.25" adapter will need grinding. Clearly you didn't. Maybe it only applied to earlier models?
