I used a motorcraft RT-1139 thermostat. Comes with a jiggle valve to help bleed air already installed and cost me 8 bucks. You won’t find any place that says they fit other than some forum posts but they do indeed work, I installed one on my MJ with the only issue being me not refilling the radiator after dumping all the coolant.

I use a Stant 205. No problems for me, and they're pretty well recommended.
I've had no problems with the stant line either
I get the NAPA gold ones. They're a reboxed stant superstat and I've never had that product line give me a dud.
Since spark plugs don’t cost that much I played around with a few. My 05 TJ like the Autolite APP985 the best. Hated the NGK ZF5RN the most.
The only one that worked for me was piaa aerovogue. No more streaking but the cost is nuts
Just got the Toyo Open Country RT Trails in LT 315 70R 17. Replaced my well worn Toyo AT IIs. They’re on my ‘17 JKU with 4 inch lift. I can tell you I hear no discernible difference from the AT IIs which had very little road noise either. The RTs feel great and look even better. I’ve not had them in the dirt yet but on pavement they’re excellent. I love them.
head gaskets blown on my 3.6 a few days ago. $3k. Not stoked. Have 193k miles. So not bad I guess.
I tried Bilsteins B8 because they said AWD and FWD compatible, but nope and the holes won't align and same for some from Monroe. The spindle that accepts the struts won't align properly.
2020 Grand Cherokee. The ASS stopped working so I took it in and they said it was because the battery was dead. They replaced it under warranty. In less than a year the system stopped working again, I'm assuming the battery again. Looks like jeep's ASS DON'T work with Mopar batteries
