Slot it into your next assembly to organize maintenance routines and unlock smoother, oil-free performance on the track.

Frequently Asked Questions

Q: Why is a scraper ring necessary for my Raptor engine?

A: The scraper ring is designed to wipe excess oil from the cylinder walls. This prevents oil from entering the combustion chamber, which reduces carbon buildup, prevents plug fouling, and ensures your engine maintains peak power output.

Q: How do I know if I need a 0.010" oversize ring?

A: This ring is specifically sized for a 0.010" overbore piston assembly. You should use this size if your cylinder has been bored and honed to 0.010" over standard specifications to restore proper ring-to-wall clearance.

Q: Can I install this ring myself?

A: Yes, but it requires precision. Ensure you use a proper ring expander tool to avoid snapping the ring during installation. Always check your end-gap clearance against your engine builder's specifications before final assembly.

Q: Does this ring work with standard top rings?

A: Yes, this scraper ring is designed to work in tandem with your top compression rings to optimize the overall ring pack dynamics, providing a better seal and reduced friction.
