Generac maintenance kits
Which Generac maintenance kit fits your generator?
Match the exact generator model/generation to current manufacturer documentation. Do not choose a kit from “Generac 18 kW” alone—Generac has changed engines, filters, batteries and product generations over time.
Direct answer
Use model number first, kit number second.
A scheduled maintenance kit bundles routine service parts for a specific generator family. Generac's own specification sheets identify kit numbers by covered kW/model families and note that oil is not included in the cited kits. Before buying, identify the generator data plate and verify that the kit documentation names your model family.

Kit numbers tied to Generac specification sheets.
These rows are compatibility examples from the cited specification families—not a claim that the same kit fits every generator with the same advertised kW.
What is usually in a kit?
The purpose is routine service—not every maintenance task.
Generac describes scheduled maintenance kits as providing the items needed for routine maintenance within the specified family, with oil excluded in the cited spec sheets. Exact filter, spark-plug and other contents should be confirmed from the kit/model documentation before ordering.
Before ordering a kit
Maintenance interval still matters
Buying the right kit does not tell you when to use it.
Generac's current maintenance guidance varies by model family, run hours and operating conditions. Extended outage operation and extreme temperatures can shorten intervals. Use the kit for the parts; use the generator's maintenance schedule for timing.

Match the battery too.
Battery specifications can change independently of maintenance-kit compatibility. Use exact model data rather than assuming every Guardian uses a Group 26R.
