For any of you Spartan customers experiencing excessive vibration in the cab there is a fix available. In our case we have three 2008 Gladiator chassis that since they were new vibrated a bit more than usual. Our mechanics persisted in finding a solution and they were finally able to track down a technical service bulletin from Spartan that addresses this problem. The difference in the cab after the rubber isolators were installed on the rig is like night and day.
