Specs At A Glance

Good To Know

Q: How do I know if my TRX 300 needs a top end rebuild? A: Common signs include low compression, blue exhaust smoke, and oil consumption, all of which point to worn rings or a scored cylinder. A compression test against the factory spec confirms whether the top end kit is needed.

Q: Does this kit include everything needed for the rebuild? A: It bundles the cylinder, piston, rings, wrist pin, and gasket set that make up the upper engine assembly. Check the condition of the cylinder head and timing components separately before starting the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
