Sierra 18-8360 Clutch Housing Seal Kit, Fits All Models 1978 and Above, Replaces OE 302540, 908194, 911019

The Sierra 18-8360 Clutch Housing Seal Kit is a complete seal replacement kit for the clutch housing, designed to restore a proper seal and prevent water or oil intrusion during a rebuild or overhaul. The kit bundles the two O-rings and the oil seal needed to reseal the clutch housing in a single package, saving the time and guesswork of sourcing each seal individually. Each Sierra product is built to meet or exceed the quality of the original equipment part it replaces, making this kit a reliable choice when servicing the clutch housing rather than replacing the entire assembly.

This kit fits all models from 1978 and above. It contains two O-rings and one oil seal, each cross-referenced to its original equipment number so it can be matched precisely to the seal being replaced. Because the kit groups all three seals together, it is well suited for a full clutch housing reseal in one job rather than piecing together seals from multiple sources.
