So I upgraded my stock Bridgestone 18' from my 2013 Sahara. I moved up to terra grappler g2's 35's. Needed spacers so I ordered two pair from Amazon- Rugged Ridge 1.5" 5x5.
Got them yesterday and figured a good rainy day to put them on.
So I get the front wheel off, decide to check spacer for fit and...
It's too small. I double checked the other one in the box. I checked the other box for both. No avail. I checked Rugged Ridge and the markings on the box- 1.5" spacer for 5x5. Everything I find online says this should be correct fit.

Nope-- don't fit. Is it possible that my bolt pattern is off somehow? Could it be 5x5.5? I'm so confused... Please help. I want to get these on before I have to drive again next week for work.

 

Measure the bolt pattern on the spacers. Maybe they were marked wrong.

 

that is why you always want to get Spidertrax. bolt pattern is easy enough to measure. If you were running stock sahara rims you have 5x5

 

Is the bolt pattern too small, or is the hub centric portion too small?

 

Here's a chart on how to.
