The top crews and shops know that minimizing piston-ring friction to the least possible drag before blow-by is one of the best ways to maximize engine efficiency. This is the ultimate tool for quantitatively measuring friction as a function
of gap and diameter. Get it right, the first time, and get the trophy! 

 

Data is Power.

DELIVERING THE DATA YOU NEED TO OPTIMIZE YOUR NEXT BUILD

The Ring Pull employs a digital load-cell attached to a patented adjustable fixture designed to isolate and pull the ring through the cylinder prior to piston-ring assembly, allowing a precise measure of ring drag against the machined cylinder surface.

This critical ring-to-bore surface friction data will help you optimize your build:

  • Facilitate engine cylinder ring preparation prior to assembly, which aids in evaluating cylinder bore surface finishes (Ra, Rz, Rk, Rpk, Rvk taper)
     

  • Compare cylinder quality in the machining preparation stage
     

  • Accurately measure the consistency of cylinder ring manufacturing (verifying ring set)
     

  • Balance ring drag from cylinder to cylinder
     

  • Accurately diagnose cylinder ring failure
     

  • Manage friction coefficients for build sheets
     

  • Analyze lubrication efficiency, and gauge engine temperatures
     

  • Measure all of the above with the torque plate installed, potentially exposing cylinder deficiencies prior to assembly
