Rubber Hump Reducer 1.5" to 2" Diameter Pack of 4

This Rubber Hump Reducer is designed to provide a secure transition between 1.5-inch and 2-inch piping while allowing controlled flexibility to absorb vibration, engine movement, and chassis flex. Constructed from durable rubber, it helps reduce stress on adjoining components and maintain a reliable, leak-resistant seal in charge air, coolant, and custom piping applications.
