Service bulletin GB2023002

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

IMT has been recently made aware that GM Silverado 4500/5500/6500 and International CV series chassis equipped with IROS (International Ride-Optimized Suspension) air ride suspension are not compatible with IMT Dominator bodies if the chassis is equipped with a rear mounted fuel tank. The air ride suspension with rear mounted fuel tank configuration requires an after frame dimension that exceeds the allowable maximum for mounting of a Dominator body.
