how many miles on wheel spacers do you have ?
is there a problem with running them really high mileage like 120,000, If I have a lift and want 35s do I need wheel spacers still?

I have an ome 4 inch lift and am about to go to 35's I put wheel spacers on before I got the lift, ( to handle a 285 70 17 tire)

I got he lift, which I needed to support the bumper and winch ( The weight of those items collapsed my stock rubi springs to less than 1/2 inch of travel)

or in other words can you run 35s with a lift without changing the back spacing of a stock rubicon wheel?

 

I've got 70k+ on mine with no issues. I do keep them properly maintained.

 

Don't have any huge numbers, but I have used the same spacers on 2 jeeps, the first one had about 30k and still have them on my Rubi with over 20k. Never had a problem. plan on using them for a long time to come.

 

130k on mine, and they are still perfect, in fact, I am selling them now. I got new wheels for a killer deal so I removed them. I was going to keep them for my winter tires on my stock rims but im going with skinnier tires so I can use the money from the spacers for other items for my jeep.

 

46000 here, blue loctite at install and have not had them off yet. Checked them at about 20000.

 

44K and no issues. As everyone has told you, use Locktite and check their torque at each tire rotation. Per the instructions, set the torque wrench 3-5 Lbs less than the stated value in the instructions (95ft/lbs for mine) and make sure the nut doesn't move. If it ever does (mine have not) take all the nuts off and re-apply Locktite and re-torque.

 

I had some 1.25" spacers from all pro off-road on my last JKU and I ran them for probably 40k+ miles with 35" tires before I sold it

 

I for one am all for spacers here. Entire time I've owned my 07, started out with 1.5", went to 1.75", then to 2", yes 2". All hub centric. All with oe wheels. Currently run Poison Spyder spacers with Method 17" x 8.5" double standard wheels.
