The Peterson Fluid Systems Chevrolet big-block left-side mount blade with A-arm fitment adapts the R4 pump’s tab mounting system for left-side A-arm installations. Complete with mounting hardware, it provides a lighter, integrated mounting solution that removes the need for a separate block and suits big-block Chevy engines where A-arm geometry is used for pump placement.
