IMPORTANT INSTALLATION NOTES:
✔ Install using OEM torque specs and clevis compatibility guidelines
✔ Arm must align straight—offset or improper angle will impair performance
✔ Verify zerk fitting access for future lubrication (if serviceable)
✔ Red piston model directly replaces older A6-3275-Z-1144 units—do not mismatch piston types
✔ Inspect for wear, clutch response, and spline integrity during maintenance
✔ Ensure slack adjuster is pre-set according to manufacturer specs before operation
✔ Only use with systems matching cam diameter and arm specs
