Description

- Caterpillar C11 (10.3L on-highway / vocational)
- Caterpillar C12 (12.0L on-highway)

Representative vehicles using these engines:
- Kenworth T600, T660, T800, W900 with C10 / C11 / C12 / C13 (1990s–2007)
- Peterbilt 379, 385, 386, 387 with C10 / C12 / C13 (1990s–2007)

Verify your engine serial number and configuration before ordering — Cat 1095309 is used across multiple mid-bore C-series engines, but the cover gasket is not interchangeable with C15 / C16 / C18 large-bore (which use different cover hardware).
