Polyurethane: How And Why It Provides Better Handling - Rod Authority

.

I've replaced a lot of dodge truck rubber bushings, boots, and mounts and upgraded them to energy suspension poly bushings and I never heard any complaints from the owners. It really changes how the truck drives. Especially the 94-02 dodges. The only tie rod boots I found to last and not be torn in a year were from energy too. Great products!

No question polyurethane is a better for handling and last much longer, I have used it in many builds, I since have went back in some builds to rubber as the road & engine vibration for a car that is going to be driven can be much rougher. I have even tried the graphite impregnated polyurethane and it still transmits vibration since the durometer is so much denser than oem rubber, no squeaks though. I had a buddy that had a '67 vette, top notch build with all polyurethane bushings, granted they never rode good but it was unbearable until he replaced the polyurethane bushings, literally you needed a mouth piece to ride in the thing and thats not exagerating much, but it handled like a slot car! On my latest build I used energy suspenion on all the suspenion bushings but rubber engine & tranny mounts and it seems to be better for my application (no road coarses here) but my car doesnt shake as badly as my all polyurethane '32 at the stoplights.
