Description
Challenger 31134 Arm Pin 1-1/2″ x 6″ – Challenger 37000 Series and Related 2-Post Lifts
The arm pin connects the swing arm to the carriage on Challenger 2-post lifts. Replace when the pin shows wear, scoring, or corrosion that allows the arm to wobble or bind. Inspect the arm bore and bushings for wear when replacing – corrosion at pivot points is common on older lifts. Confirm pin dimensions (1-1/2″ diameter x 6″ length) match your lift’s specification before ordering.
