Any structural engineers out there? I put the 6" Teraflex LCG kit on my unlimited. My wheels have less backspacing than the stock and I have 13.5 wide, 37" tall tires. My stance feels a little narrow and rolling a $50k rig wouldn't be too fun. Does anybody know whether some 1.5" spacers would really make much difference to your tipping point? I've also read on here that spacers are not recommended for wheeling. Thanks for your input.

 

I put the Teraflex steel spacers on mine. They are 1.25" but I can really tell a difference and I only have a Teraflex 2.5" coil lift.

 

I've got the TeraFlex 6" long arm as well plus some more and am running 40x15.50 tires. I added TeraFlex 1.25" wheel spacers to alleviate some full flex rubbing issues and am impressed at the extra track width I have achieved.

 

I run the Spidertrax 1.5 inch spacers. That 3 inches makes a big difference, not just in looks, but in stability.

I didn't know that I am not suppose to go off road with my wheel spacers? I did I break my warranty or something.

 

There is no issue using spacers on road , offroad , in outer space ... anywhere.

Good quality spacers "spidertrax" are proven to be free of problems and hold up to anything.

Not in my opinion. We have customers you have been running spacers for 5,6,7years with zero issues at all.

After trying to work my way around it I am going to run SpiderTrax 1.5 spacers. I run 37's and have had to adjust my steering stops to eliminate tire rub on the frame in the front wheel wells. At this point I would rather go out then up. I NEED my turning radius back.

 

I can't see why wheel spacers are any more of a concern than rims with non-stock back-spacing--it's the same thing. No one seems to worry about rims with different backspacing, but there seesm to be ongoing concerns about wheel spacers. I don't see the difference....

ok, so wheel spacers may or may not be a problem. But does anybody know whether the extra 3" of width the add will help provide a measurable benefit to reducing the chance of roll-over? To me that's the point of adding them. I don't care about the way it looks and I don't think I have any rubbing issues. Thanks!

 

This is a good point. As far as bearing wear, its similar to as if you were running a wheel with different backspacing. Lesser backspaced wheels are pushing your wheel further from the bearing and thus creating a larger moment on your bearing from the reaction force from the ground. The spacers would not change this. There were issues many years ago with poor quality spacers and that can be very dangerous if they were to fail. This is why places like discount tire will not work on a tire with spacers. They won't even touch them. However, the newer spacers are very reliable and have worked well. The only reason that I do not run them and opted for different wheels is due to the fact that discount tire does not work on them. My jeep is in there far too often for rotation/balancing/occasional air up for it to be worth it to run spacers over wheels. Plus, I run steelies which aren't that much more than a good set of spacers.

The newer spacers(spidertrax seem to work well) have proven very reliable and I have only heard of one instance on this forum where they did fail. However, this could have been caused from a number of things including proper torqueing and maintenance.

The extra width is a great thing for preventing rollover. Once the CG of the vehicle moves over the wheel in an off-camber situation, rollover happens. The wider the stance, the more side-angle it takes. My butt usually gets a major pucker long before that point though.
