Supported Servo Master Kit

"Mystery" band failures are a common result of aftermarket servo return springs and weak OE springs prone to collapse that do not reliably release the servo. The Sonnax spring in this kit is race-calibrated to ensure consistent servo function for longer band life and a cooler transmission. The spring's higher seat pressure helps ensure full servo release, but also features a lower spring rate to prevent excessive release force in the apply position.

 

  • Unique cover and pin combination eliminates piston binding that causes unexplained band failure
  • Race-calibrated spring counteracts pin bias effect up to 275 psi
  • Dual PTFE seal rings for better seal and low friction
  • OE apply area
  • Low-profile design ensures adequate clearance
  • 6061 Anodized billet aluminum cover
