Just lifted my JL with Metalcloak Dual Rate 2.5" lift with 37" Toyo Open Country MT's & 17" Icon Rebounds wheels. As soon as I got on the highway it starts bouncing, it actually started around 55+mph. Why does this happen & what can I do to stop it?

Welcome to the Forum, from Cave Creek AZ.
At that speed, either a bad tire, or tire balance. Them big 37’s need to be Road Force Balanced.

I suspect they overfilled your tires. take them down to 26, maybe 28 PSI and you'll be fine (y)

Welcome to the forum!
Good to know, I'll try it out. Thank you!

OK cool...I'll look into this too! Thanks?

Welcome to the forum!

One thing that hardly gets discussed: going from a 10-inch wide tire to a 12.5-inch wide tire significantly increases the contact patch, making it more prone to feel more of the road, imperfections and all.

Update
First...Thanks for all the feedback! & sorry I forgot to update on my issue. It's no longer an issue! 😁
The bouncing went away after 2 days. I'm not sure why or how but I'm assuming I just need to drive around a bit??? Idk.
My tire pressure is at 38psi, is that normal for 37's? What do you guys recommended my psi to be for daily driving vs off-road?

Way over inflated for tires that size. Try 26-28.
