Materials Designed for Slip Converters

  • HTS - Designed for high-thermal capacity applications. Replaces spun-wound, woven or other carbon-based materials.
  • WC - Genuine OE woven carbon material developed by OEMs for continuous slip GM and Ford applications.

Materials Designed for Full Lockup Converters

  • HTE - Thermal capacity of Kevlar®, with improved consistency and shudder resistance.
  • HTL - High thermal and exceptional torque capacity for the most demanding torque-holding applications.
  • XTL - 30% More torque holding capacity than HTL. Available only for a small range of extreme-duty lockup applications.
