HRB Piston Ring File Kit

Achieve precise, repeatable piston ring gaps with the HRB Professional Piston Ring File Kit. Developed by experienced engine builders, this advanced kit removes the guesswork from ring gapping by combining innovative design with precision engineering—delivering consistent, parallel gaps every time.

At the heart of the system is a zero-backlash bearing shaft paired with an ultra-thin diamond wheel, allowing smooth, controlled material removal on both sides of the ring. The result is even, parallel gaps that are critical for optimal ring seal, engine performance, and long-term reliability. Built with a rigid billet alloy body and stainless steel shaft, this kit is designed for durability and accuracy in demanding workshop environments.

Spare diamond wheels are available to keep your setup performing at its best.
