Not exactly the same, but similar enough. I stacked two of those TF .5” spacers at all four corners on my Jeep. Wanted 1” spacers but nobody seems to be selling them that way. Most have a different height spacer for the front than the rear.

No issues thus far.

These spacers are designed to stack if you wish. They have held up great stacked.
I am leaning to the right about 3/8".

Can these be ground down to 3/8 or 1/4? I want to add a shim under the rear RH spring which I think is the culprit (Mopar lift kit). Shimming one spring will adjust the dynamics on all four, I just don't need a full1/2" . And I don't even want to attempt to have Mopar warranty the spring, that would be a nightmare.

That is most likely caused by the gas tank being on the right side of the Jeep. We saw it with the JK and we are seeing it with the JL. The amount of lean will be different depending on the level of fuel.

It was leaning about 1/2" in the front RH, and about 1/2-3/4" in the rear RH. I took it all apart and started by adding your 1/2" spacer in the front RH only, got better, then rear RH, and it's probably as good as it gets. Between 1/8 to 3/16 lower in the RH front, and between 1/4 to 3/8 lower in the RH rear. Still see the lean, but it's something I have to live with. I measured all the springs, the two rears were the same or barely a 1/16 different, the fronts were almost a 1/4 different, being the RH was longer which should have stopped lean. I am guessing the rear RH should have been longer also, but apparently they should have both been 1/2 longer or at least stiffer. Such a pain in the ass.

Glad to hear those made a bit of difference. One of these day I believe Jeep will re-position the fuel tank to the center. Until then, i guess we will live with the lean!

It's not the fuel tank, the lean is on empty and with my 250# azz sitting in the drivers seat (which I weigh as much as 41 gallons of gas). It is either the Mopar springs in lift kit, the frame itself where the spring isolators go, or????? It's ridiculous for a manufacturer to put a 56K list price on a vehicle that is not level. That in my world is junk.

Do you have a link, part number for the stackable .5" TF front spacers?

If you're looking for just the front spacers, you'd want kit part # 1155110.

I want to run a 1" spacer in the front and a .5" rear to reduce rake and maintain current wheel well clearance. I don't see just a 1" front spacer, which is why I'm asking about stacking. I was interested in the 1.5" leveling kit, but since my rims are OEM 17x7.5 apparently the rear sway bar link will contact the wheel/tire due to a backspacing issue.

TF, can you please confirm how large (if any) of a rear spacer can be used on the Willys oem 17x7.5 wheel to avoid a contact issue and what stackable spacers can be used to achieve a 1" lift in the front? I probably plan to run 285/75/17.

We do actually have a set of '1 inch spacers, which are found under part #1155100 for reference. You can stack the 0.5 spacers together to accomplish the same thing, it's up to personal preference really.

It gets tricky using OEM wheels with no spacers or added parts. Technically, you can add however much lift as you want without issues and everything "fits". However, the rear sway bar links can get close enough to either A:, contact the lip of the wheel, B:, contact the tire sidewall, or C:, both. It's why we spec out 4.75 or less numerically wheel backspacing on our kits.
