body mounts, which are preferred? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Getting ready to purchase some body mounts and was wondering what kind you are running, what kind are best, and the pros and cons of each of them might be?

Thanks - Jeff

I am looking into the same thing, just for reference. Does anyone make polyurethane ones?

I think Energy Suspension poly body mounts are the vendor of choice and I think PST makes them in graphite impregnated poly which are as good or better.

What would be the diff from polygraphite vs. stock rubber replacement? The life span of the mounts themselves? Would the ride be harsher with them?

Jeff,

when I replaced mine, I went back with stock rubber mounts. I have Energy Suspension bushings everywhere except for body mounts. I didn't want to feel anymore vibrations in the cab than I do now. The stock rubber will absorb more of it than polyurethane. Of course, I would wait until someone who does indeed have poly mounts to reply before making a decision on what I would do.

One thing I do know for sure. When I replaced my motor and tranny mounts, it really added to what you felt in the cab. It sure makes it easier to feel the engine running. I rather like it though.

I am using PST on my trucks this time around. Originally I had Energy suspension. PST body mounts are NOT polygraphite, they are just poly, no need for the graphite since they don't rotate.

Yes lifespan is different, poly doesn't deteriorate like the rubber does.

You WILL feel more through the cab with the poly than rubber, but I didn't mind it, but it isn't bad. Cab movement moves with the frame. It isn't bone jarring or anything, you just can tell it isn't "floating" anymore. Keep in mind that new rubber will be almost as stiff in comparison.

Just got the new JC Whitney catalog. They have what they call a Prothane Total Kit. For 81-87 2wd trucks they give you the leaf spring bushings, Body/Cab Mounts, Outer tie rod end boots, swaybar mount and end link set, Control arm set and transmission mount. Price$182.95. They also have just the Prothane body/cab mounts for $58.98

**swervin ervin** · 03-06-2003, 06:32 PM

Don't buy any Prothane bushings. They are crap. I bought some Prothane leaf spring bushings before, as well as some sway bar bushings. They are not in Energy Suspensions class.

82 Silverado 4X · 03-06-2003, 07:07 PM

Mike. Thanks for the info on Prothane. That's what makes this board so valuable. I was thinking about buying the Total Kit for my 77 Blazer Chalet but now I know to keep looking for a better product. The camper unit adds quite a bit of extra weight and the stock originals are flattened out so far that the body actually touches the frame in a few spots.

NP George. I found out the hard way that all polyurethane bushings are not created equal. I swear by Energy Suspension, others like PST. Never having used PST bushings I can't say anything at all about them. But, I can with Energy Suspension. From the info gathered in this forum, I don't think you could go wrong with either company.

WORD to Mike's last reply. Energy Suspension and PST (<--- My favorite!) both are great companies. I will be replacing my cab mounts soon, and was wondering if anyone has suggestions? Any particular tips or things I should avoid?
