Everything Needed to Restore Your Outlander 850 Top End

The Can-Am Outlander 850 Master Top End Rebuild Kit is designed for complete top-end repairs on 2016-2023 models. It includes new cylinders, piston kits, intake valves, exhaust valves, and a top end gasket set to help restore compression and dependable engine performance.

This kit is the right choice when your cylinders, pistons, and valves all require replacement. However, if your existing valves remain within specification, the Complete Top End Rebuild Kit may be a better fit for your rebuild.
