## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [Engines > All Horizontal Pit Bike Engines](https://tboltusa.com/store/engines-all-horizontal-pit-bike-engines-c-114_1034.md)
- [Engines > Pitster Pro Engines](https://tboltusa.com/store/engines-pitster-pro-engines-c-114_117.md)

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.
