Which one is better? I recently installed some MOOG endlinks on my car to replace the rubber ones, and with the handling kit I already had, its, in a word, fun.

Ive just been doing a little looking around, and it seems that the MOOG endlinks are almost all made of thermoplastic, and of course Energy Suspension is polyurethane. The limited research I have done suggests that thermoplastic is better than polyurethane, but never really says why.

Another thing to consider is price/availablity. I picked up 2 endlinks for less than 10 dollars from a local auto parts store. I know a few places carry Energy products, but the rest have to ordered and with shipping can be approaching 20 bucks. I know its a minimal difference, but 10 bucks is 10 bucks, and if I can get the same thing or better locally, now, and for cheaper, Im going to be all over it.

Intrigue
That is the kit for my car from Summit, who I would assume knows what theyre talking about, and it lists it as being thermoplastic.

They also show 2 different endlinks for the Bonneville, and Im not entirely sure why, but they also list them as thermoplastic

So basically Im wanting to discuss, is thermoplastic better than polyurethane, if so why. I would also like to prove by this that the MOOG endlinks are just as good as if not better than Energy Suspension for a lower cost and better availability.

Have at it guys.

How about spicer endlinks? Just adding on another brand.

i have MOOG on mine... car is on rails

I've got the blue Moogs on my 1998 LeSabre. They were cheap, way better than stock rubber, and I am happy with them.

I don't know whether they're any better than Energy or any other brand.

I installed the Engery Suspension Endlinks on my Bonneville this summer, the difference the poly bushings make is unbelivable.
Would never go back, handles WAY tighter.
Ive also ran moog products, on my first ssei, all Endlinks were moog as well as all 4 unjoints..snugged it up a bit..
