Available in 1/2" thickness, with two gaskets (carb studs are optional). The spacers also act as a Base Insulator to reduce heat soak (transfer of heat) to the carburetor. This keeps your carb cooler, thereby reducing vapor locks and/or other associated problems. 1/2" spacers are now custom made from solid phenolic for maximum insulation.
