Shocking?

Replacing shocks should not be a bad issue. See if you can get loaded after putting them all on

 

Only on gas shocks are they necessary.

 

OEM shocks are usually made by a major shock manufacturer like Gabriel, Monroe or Sachs to the OEM’s specifications and stamped with the OEM’s name on it.

A couple years ago I replaced the cab shocks on my Volvo. I went to Volvo to buy the OEM shocks, when I opened the box the shock had Monroe stamped on it.

 

I ordered Gabriel Adjustable E through autozone. They came in TRP box. I think that TRP is PACCAR's version of Alliance, which is Freightliner's parts

 

Sounds like they are hydraulic shocks, (not gas charged). Hendrickson installs gas shock on the Intrax suspension that’s under the tank trailers I work on. Before I knew there was a difference i’d Just by some Monroe (or whatever would fit) but we had a trouble with them blowing out in off-highway rough road conditions. I went back to the Hendrickson brand, (which turned out to be less expensive). I’m not sure if they work better, but I don’t have to replace them as often!!

From what I learned from a parts salesman, the hydraulic shocks are ment for air suspensions as they are supposedly shock evenly both ways. Although if you have problems with gas filled shocks, the hydraulic shocks hold up better in rough conditions in my experience.
