Red Eagle Friction

Red Eagle Friction is the go-to material for most performance applications. The lining has a unique dual saturation, which imparts high friction coefficients and high heat resistance. Red Eagle clutches are designed to limit the amount of "slip" by providing a shorter lock-up time, generating less heat.

Our proprietary process starts with the friction paper saturated in a phenolic resin, cured, and then saturated a second time in a silicate. The silicate imparts high heat resistance.

Red Eagle clutches:

  • Are designed with a softer, more resilient base paper.
  • Assure less wear against opposing steel plates.
  • Reduce the incidence of steel plates burning and warping.

Kolene® Steel

Kolene® is a salt bath nitriding process. In generic terms, it is a thermochemical diffusion process, whereby ferrous parts are processed in molten salt with a specific nitrogen potential. In plain English, it provides a surface treatment that enhances wear and fatigue resistance from 200% to 500% which offers higher heat resistant and increased lubricity.

Kolene® Steel

  • Strengthen wear characteristics
  • Increase fatigue strength
  • Enhance lubricity

Kolene is a registered trademark of Kolene Corporation.


Alto created extra capacity clutches.

The concept was originally developed for the TH700R4 3/4 pack. It has since been enhanced for many of todays High Energy applications.


  • Increased surface area for increased holding
  • Increased surface area for increased heat absorption
  • Increased surface area for shorter lock-up time - decreasing "slippage"
