This exhaust gasket from Quad Logic is manufactured from a thick stainless steel mesh wrapped in an outer layer of graphite. It is designed to perform even better than the stock Polaris gasket. Exact replacement for your Polaris. Most Trailboss and Trailblazers use TWO gaskets total: one between the short head pipe and main pipe and another between the main pipe and the muffler. Be sure to order 2 if replacing both. Sold each. Replaces Polaris 5243517. Fits the 2008-13 Trail Blazer 330, 2000-02 Trail Boss, and 2003-13 Trail Boss 330 models.
