Overview – KIT, GST 4089239
The Cummins KIT, GST 4089239 is specified for Cummins overhaul and service positions as the GST gasket kit and is supplied to the original dimensional and material standard.
Parts Characteristics
A gasket kit that bundles the seals and gaskets for a defined service – the joints of a head, a pump or a cover – so a planned job has every seal in one box. It carries the small parts that, missing, stop a rebuild, so a complete kit keeps the job moving.
Applicable Models & Applications
Used at Cummins service positions specifying this GST kit. Match the kit to the assembly it serves – gasket kits differ by engine and by coverage.
Maintenance & Replacement
Replace every gasket in the kit at opening rather than reusing old ones. A gasket carried over weeps, and the weep is what stains the block.
Confirm the coverage matches the job before you start. A kit short by one head gasket stops the rebuild at the worst moment.
Keep the kit sealed and clean until fit. A gasket set stored open collects the grit it was meant to keep out.
Keep the correct GST kit for your engine on the bench. It is cheaper than an open engine, and it is exactly the box missing when a service needs every seal today.
Price Reference (USD)
The KIT, GST 4089239 generally falls in the USD 40-220 bracket, with expedited freight quoted separately.
