JEGS Holley Billet Aluminum Anti-Reversion (Shear) Plate
A unique product for Holley carbs. Provides a low pressure area under the throttle plates for improved signal to the booster while assisting with reversion from the overlap of the camshaft by turning the air around as it is pushed up through the carb. The 7 degree taper and the sharp edge have been engineered to make Holley's perform at their peak and to gain the most power from your combination. An additional benefit to the 4500 plates is that it serves as a safety plate and prevents the internal linkage from falling into the engine in case of separation. Clear anodized 1/2'' thick 6061 aluminum. Installs with flat surface against carb, view shown is plenum (intake) side. Made in the USA.
