Energy Suspension Body Kit
Anybody running the cab and core support mounts? They appear to be less expensive than the stock units.

I have the prothane ones on both my trucks. Bought them from JCWhitney. I recommend replacing your existing hardware also. The prothane kit comes w/ the rear bolt/nut.

Just a thought here. Urithane body mount kits take all the flexabillity out of these trucks that they were designed to have. These trucks do not have rigid frames, they are "C" channel frames designed to flex and bend acording to the terrain. This is why the frames are riveted and bolted together and not welded. Rivets and bolts alow for flexabillity and so do rubber body mounts. On the other hand, the cabs and individual body parts are welded together and can not withstand the flexing the chassis is designed to withstand. The rubber body mounts allow the frame to move indipendantly from the body, and also absorb vibrations from the road. The end result is going to be rattling cabs at best and bushings pulling through their mounts at worst. I would think long and hard befor I stick a set of the urithane mounts under one of my trucks.

By the way, can anyone tell me the advantages urithane body mounts have, besides they may be a little cheaper? I hear that they may last a little longer. But either one of these advantages do not outweigh the disadvantages. Do they make the truck handle better? I don't think so because they are not suspention related. WES www.ClassicHeartbeat.com

And I'm not so sure they last longer either. I put urethane body mounts on my blue K20 and three of them have went bad in 10 years. The truck also doesn't flex. I noticed I have another one that is coming apart right now under the cab.
I agree with Wes, I put the stock rubber mounts on my latest green one. The original ones were 33 years old and still looked good. Just my two cents. ![]() |

I also have Poly bushings on my truck, and I am happy with them. I do believe the ride to be a little stiffer, but not terrible. Wes, what you said does make sense though, but If the truck is more of a street truck, wouldn't you want a stiffer chassis? Isn't that why we put sway bars on? I too can see the benefit of rubber on an offroad truck, but on a street driven truck, what's the harm? I hope I'm not sounding like I'm attacking anyone, just trying to voice my opinion.

I ordered mine from AutoZone. Looked up all the part numbers and pricing on line. Summit and others were cheaper on some but with the shipping costs AutoZone turned out to be cheaper. I just went into my local store..gave them the part numbers and picked up the parts within two days. No shipping.
Oh yeah....I got mine in all red and Summit and others didn't show these part numbers.

crazy longhorn, I am just curiouse as to how poly body mount bushings help you launch straiter. Does the cab and radiator core support stiffin up the frame. I can understand how poly motor mounts would be help keep the engine from flexing, somehow changing the angles on your clutch linkage, but how do the body mount bushings help? jorgensensc, I don't think that you are attacking anyone. You are right urithane bushings would not harm a street truck nearly as bad as an off roader or heavy hauler. However, just because it is a street truck doesn't mean that it doesn't flex. There are speed bumps, ramps into stores, uneven road surfaces, uneven parking lots, and etc. A truck does lots of flexing wether or not it is on the road or off. WES www.ClassicHeartbeat.com

It sounds like you stiffened your frame. In the instance where a frame does not flex, poly wouldn't do any harm because there isn't any independant movement between the chassis and body. WES www.ClassicHeartbeat.com

yes, the addition of the heavy cross sills on the box did effectively stiffen the frame(I think). the truck is much firmer to ride in, But not a complaint. if I jack up 1 corner, she still flexes somewhat, just not like factory. The old wood floor boxes IMO , had more flex than the steel floor versions. I still need a little help up front, but i think a good swaybar & bushings will help. I sure do agree that the stiffer cab bushings may not be for every build, just a matter of useage
