OEM underfloor mounting kit with secondary vibration isolation for KY and KYD series generators. Includes generator tray, brackets, and hardware. Exhaust tailpipe not included.
The Cummins Onan A030X652 is the OEM underfloor mounting kit for the KY MicroQuiet (QG 3600/4000) and KYD Camp Power generator series. It is designed for installations where the generator is mounted directly to the RV floor or floor support structure from below â as opposed to a side-access compartment installation. The kit includes a powder-coated black generator tray plus all required mounting brackets and hardware.
A key feature is secondary vibration isolation, which reduces the transmission of generator vibration into the RV floor and frame. This is particularly valuable in underfloor installations where the generator is mounted directly to structural members rather than enclosed in a sound-dampened compartment.
An exhaust tailpipe is required to complete an underfloor installation and is not included â Onan 155-2845 (KY tailpipe kit with clamp and hanger) is the recommended companion part for underfloor KY installations.
Isolation mounts reduce transmitted generator vibration to the RV floor and frame â important for comfort and long-term structural health in underfloor installations
Black powder-coated tray provides corrosion resistance for underfloor environments exposed to road debris, moisture, and temperature cycles
Brackets and all required fasteners included â no sourcing separate hardware for the mounting structure
Engineered specifically for the KY/KYD generator footprint â ensures correct alignment, load distribution, and fit with OEM installation dimensions
This kit provides the mounting structure only. A complete underfloor installation also requires an exhaust tailpipe routed from the generator muffler to the RV sidewall exit. The recommended companion part is Onan 155-2845 â the KY series tailpipe kit (includes tailpipe, clamp, and hanger) specifically designed for underfloor and sidewall-clearance installations.
The A030X652 is for underfloor installations only â where the generator attaches directly to the underside of the RV floor or floor supports, exposed to the exterior. This is a different installation type from compartment mounting, where the generator sits inside an enclosed side-access bay. If your installation requires compartment mounting, a separate compartment mounting kit applies. Consult the KY series installation manual or your Cummins Onan dealer to confirm the correct kit for your application.
