Poly vs Rubber Cab Bushings - need opinions

Anybody got experience with Poly cab mount bushings? Got some red Energy Suspension ones installed today and was wondering if anyone has long/short term experience/opinions. thanks

i did not care for the extra vibration when i tried the poly bushings on my daily driver truck and took out and threw them away when i went back to facory rubber type

with poly bushings my cab didn't sit correctly on the frame and the front clip took alot of tweeking to get it to even be close. I switched to rubber bushings and everything lined up perfectly! bushings were designed to give. less give = rougher ride, more vibration transmitted from drivetrain to driver.

I do not like anything that is pure polyurethane. I had a terrible time with it squeaking on a couple of projects many years ago and vowed to never use it again. I prefer rubber or poly-graphite where available.

I'm of the other camp, I like them.
Have had them on about 6 years now. I didn't have any cab fitment issues, can't recall what if any vibrations changed, nothing that got my attention anyway.

Thanks everyone for your feedback.

The issue with me - I've got mine replaced (was worn factory rubber, cracks) - but also the suspension (ball joint, shocks) has been pretty much shot ever since I've gotten it (10 years ago) - so I don't even know if I'll notice a difference between the the two afterwards anyways.

I'll be reassembling the truck soon, so I hope it doesn't cause fitment issues.
