Has anyone found a set of energy suspension poly body mounts for the LMM? Not sure if the older body style will work on it. I called around and not having any luck. Thanks you for any advise.

Just got a set of Prothane poly body mounts for my LBZ.
They are quite nice, I would check them out for your LMM.

gimme the low down. What are your likes/dislikes? How long have you run them etc...

I have the new hydro rears but considering doing all poly since the price is so good.

Unfortunately I have to install them. I am going to pick up the "hydraulic" rear mounts from the dealer today to go with the rest of the poly bushings. First impressions are very promising. The molds are all very good with no excess mold trimmings. The entire kit is the same price as the two hydraulic rear mounts, so they are prices nicely too.
I will be installing them most likely this weekend and ill give a little review of how they are.

please update when you have a few days driving with them. Don't really care how they look, I do care how they make the truck feel though.

What about ride quality, harmonics, etc? Body creaks etc...

I live in the northeast and our roads are complete garbage. Every street is like offroading, not exaggerating. I love the price point and lifepsan of the poly, but if it kills my ride on these crap roads I won't be pleased with my choice

I'm in the same boat I want the poly for the lifespan but if it makes it stiff and squeaks like crazy I don't want em

Lubed them up before putting them in, I don't have any noice from them. The only bushings on mine that are not Polly are the rear leaf springs. I have them, just haven't had the chance to out them in.

I have ran the poly mounts in my ec/sb lbz for almost 2 years now and can say I wish I had put the factory mounts back in. the poly mounts make the cab flex more and the ride is not as nice as the factory mounts. this of course is my opinion.

Finished the poly mounts with the hydraulic in the rear. OH MY GAWD. It rides amazing. The ride is sooooo much smoother, the body flex is very minimal, and if you had a jarring motion over bumbs, it removes that. The only thing i though was weird was you can feel a little engine harmonics in your seat. Kind of like your phone vibrating but less.
Overall great buy and would recommend this set up to anyone trying to get a smother ride in their truck!:thumb:

I've had em for around a year or so and like them. But I also have every rubber bushing or mount replaced with poly. The only rubber that remains are the engine mounts and transmission mounts. Never squeaks at all - and mine are even the red ones without graphite.

More like a sports car like ride than anything, driving a stock truck feel terrible now because mine doesn't have the sloppiness and body roll that comes with softer rubber.

BE WARNED! They absolutely increase in cab noise and vibrations from the road, engine and lift pumps. 20-30% at least! and take into account I had sound deadening(like $500 in materials worth) prior to installing the full poly kit too.

But to clarify, you are still you did it?

And nice OP. Let us know after a couple days how you feel. This is way cheaper than sourcing OEM mounts

Oh yeah, I personally don't mind it until something starts vibrating with a passenger in the car (door card does it occasionally). That's the only bad part, the ride I love. I can't stand being in vehicles that people describe as if you're "floating on a cloud" - to me that's a design that sacrifices handling for comfort.
