The Fisher and Western 27530 is a genuine trip spring spacer, designed for use on Fisher Homesteader and Western Suburbanite snowplows. This small but crucial part fills the void on the trip pin, effectively taking the place of a fourth spring on plows that only use three. As an authentic factory component with an inner diameter of 1.032 inches, an outer diameter of 1.250 inches, and a length of 1.250 inches, it ensures proper tension and reliable trip performance.
