• Material Strength: Alloy construction endures high temperatures without deforming.

The BTR030R3 SKU fits seamlessly into aftermarket piston assemblies, helping mechanics organize rebuilds efficiently. On race day, it translates to smoother revs and quicker recovery from downshifts, keeping you ahead in the pack.

Don't overlook this vital piece—it's your ticket to a more responsive engine that powers through laps with consistency.

Frequently Asked Questions

Q: How do I know if I need a 0.030" oversized ring?

A: You should use a 0.030" ring when your Raptor engine cylinder has been bored out to 0.030" over standard size. Always measure your cylinder bore with a precision gauge before purchasing to ensure the correct fit for your piston assembly.

Q: Is this ring compatible with standard-bore Raptor pistons?

A: No. This ring is specifically designed for a 0.030" oversized piston. Installing an oversized ring on a standard piston or in a standard-bore cylinder will cause engine failure or prevent the engine from turning over.

Q: What is the best way to install this compression ring?

A: Use a proper piston ring expander tool to avoid snapping the ring during installation. Ensure the ring gap is oriented away from the thrust side of the piston and that the ring moves freely in the groove before inserting the piston into the cylinder.

Q: Should I hone the cylinder before installing new rings?

A: Yes. A light hone is recommended to create a cross-hatch pattern on the cylinder wall. This helps the new ring "seat" properly, ensuring a tight seal and optimal compression for your race engine.
