The SP1 Exhaust Spring Damper is engineered to mitigate vibration and noise by fitting directly over the factory exhaust spring that connects the top of the pipe to the belt shield. This component is specifically designed to replace the Arctic Cat part number 2612-949, ensuring a precise fit for the original spring assembly. The damper features a silicone sleeve with exact dimensions of 12.0mm inner diameter, 16.0mm outer diameter, and 38.2mm in length, providing a consistent interface between the moving spring and the surrounding chassis components.
Constructed from silicone, this hard part serves as a protective and dampening layer for the exhaust system. While optimized for the specified Arctic Cat application, the design allows for versatility across other snowmobile exhaust springs, provided they accommodate the stated sleeve dimensions. By addressing the specific mechanical interface of the exhaust spring, the SP1 damper offers a targeted solution for maintaining system integrity and reducing operational wear on the connection point.
