Product Details

The Federal-Mogul R-9985 5 is a Speed-Pro performance piston ring set engineered for high-output street and racing engine applications. Federal-Mogul's Speed-Pro line is built upon more than 100 years of engine component expertise, delivering precision-fit rings designed to minimize blowby and maximize cylinder sealing efficiency.

The "5" suffix in Federal-Mogul's R-series designation indicates a +.005" file-fit oversize, making this set ideal for engine builders who require precise end-gap tuning during assembly. File-fit rings allow the builder to custom-set ring end gaps for optimal performance in racing and high-performance street applications.

Speed-Pro Ring Set Features:

  • Precision-manufactured rings meet or exceed OEM dimensional specifications for proper fit and sealing
  • File-fit design allows custom end-gap setting for performance and racing builds
  • Engineered to reduce blowby and maintain consistent cylinder pressure
  • Available in oversize to accommodate bored engine blocks
  • Part of Federal-Mogul's trusted Speed-Pro performance engine components lineup

Federal-Mogul Speed-Pro piston rings are a preferred choice of professional engine builders for rebuild, performance, and racing applications. Always verify bore size and ring groove dimensions against your specific engine block specifications prior to installation.
