    ok, I want to run poly mounts on my drivetrain. Question is, what brand/model to go with? I did a search on summit, and came up with...

    ENS-3-1116R

    PTP-7-506

    PTP-7-509

    pretty sure I have what most peeps call the "clam shell" style motor mounts on my '85. The top two listed above seem like a simple replacement. Summit says the bottom one will work too... I dunno. What do you guys run? Any specific manufacture/design/model I should go with? None of these are budget breakers.. I just want the best poly mount I can get. I seem to remember seeing a pic of a clamshell-type mount that was just ****ered all up... is there a better-designed replacement?

    I did a search, found lots of people saying "go all poly, or all rubber, but don't mix them!"... but not much info on which poly bushings to run...

    The bottom one is for a first gen:D

    I would go witht the energy suspension(top) they are $15 less expensive for the same thing.
    Just remember that price is for one.

    that answers that! :thumb: thanks...

    ok cool, sounds good.

    anyone else wanna chime in? I need to order a whole bushing kit for my tow rig... and some trans or body mount stuff (not sure yet) for my custom doubler x-member anyway... so I'll save a boatload on shipping!

    energy suspension. Remember to change your tranny mount to poly while you do the engine. Or else you will be braking mounts

    yeah, everything is gonna be poly for sure.

    right now I have no trans or t-cases, so it isn't a problem. ;)

    I'm not 100% sure what I'm gonna use on my doublers crossmember... I want (duh!) the flatest belly possible, so the standard t-case mounts aren't going to work... at least, not like they do on a stock rig. I plan on having a piece of plate bolted directly to the bottom of the adapters (203 and doubler) and then having tube or something run up from there... terminating with some kind of bushing that is attached to the crossmember itself. Small factory body bushings off a jeep or a trans mount or something maybe... I dunno. :dunno: I know after talking with BD that I don't want the bushings to be all the way out at the frame, because that won't allow for hardly any flex... they will have to be right next to the adapter... but somehow not below its mounting-face. lol.

    anyway, enough hijacking of my own thread... any more opinions of poly motor mounts? :thumb:

    What I have heard as rule of thumb...You can combine poly motor mounts with rubber tranny mounts, but not the other way around. I would rather have all poly or all rubber:D

    There have been a couple of posts where people had problems installing these things, might search for them just to know what to look for.

    I know on mine, the motor mounts were aftermarket and the clamshell stamping was designed different, and wouldn't allow me to use the energy inserts.

    I think the Energy suspension is more expensive than the Prothane. It looks like the Prothane actually comes with both mounts in the kit. I could be wrong, but that's the way it reads.

    i like the mounts ord sells.. pricey at first but then you just need to replace a bushing, (looks the same as one for a spring eye)

    Yes the Prothane does come 2 in a box. They were a pain to get to line up with the motor plate holes. They eventually did, and work well.

    Those get my vote.
    Could also go with the originator of that type of mount, Autofab

    Ord sells them for $170 vs Autofab's $220:eek1:

    I think summit and jegs have them too.

    thats it huh. Considering the simplicity of it, I'm surprised DIY isn't making something like this already.. for a lot less coin...

    time to PM Kurt I guess...
