Do Sulastics reduce the bucking and jumping on concrete roads?

They can, but before installing them, I would consider:
1) are the rear shocks shot?
2) do the rear tires have too high air pressure?


You might also consider adding what vehicle/options/upgrades you have to the signature area of your account, so it's automatically appended to your posts.

Updated signature finally. Shocks are new OEM and I have about 7000 lbs. rear axle weight when loaded so I have been running about 55 psi in each rear tire.

Thx

OEM shocks aren't considered the best, but they should still work ok.




If you are concerned with the ride when loaded (and 7K lbs on the rear axle sounds like it), then sulastic shackles won't help, as they are designed to help primarily when the truck is unloaded. In this case, air bags probably would help more, but someone with actual experience with them might chime in.

Davester, just looking to see if the rubber shackles help on concrete roads when unloaded. I agree not much i can do when loaded other than air bags or something similar.
Thx.

The rear cab mounts are fluid filled (they call them hydraulic mounts). They can leak out (rusted shell or torn rubber). They are the first thing that I would inspect.

I haven't personally used them (considered it, but they are kind of expensive and now I generally drive around with a trailer, so they make less sense for me), but I've read that some people feel they work well for improving the ride of their truck when it's not loaded. The main issue I've read about them is getting the right set for a particular truck, as they have to work at a relatively narrow weight range, that has to match the weight of the rear end of your truck.


If you do decide to get them, I would suggest directly contacting Sulastic, and get their recommendation for which model to put on your truck (contact via email/phone, not using their wesite to select it).

Rear tires @ 55 psi when empty should be ok, loaded probably should be around at least 75 - 80 psi.
Iím happy with my Sulastics, mines the HDD model, I donít know what one is for the newer trucks. Give Sulastic a phone call.
On concrete highways Sulastics should help, mine road better all around, tire psi when empty is one factor.

Try the chalk method, drive for about 100-200 yards on a flat section, I usually do this in a mall parking lot.
Check the wear pattern, then adjust your tire psi where you get it even across the tire.
