Running dual carbs on a tunnel ram intake or a blower? This Speedmaster linkage kit makes connecting them a whole lot easier. The PCE476.1001 kit is designed for two carburetors mounted sideways (side-by-side). The best part is the progressive linkage—it opens the primary carburetor first, then the secondary, for smoother throttle response and better driveability compared to both opening at once. The kit includes all the necessary rods, brackets, springs, and hardware to set it up right. It's built tough from Speedmaster's 'Track Proven' line, meaning it's designed to handle the vibrations and demands of high-performance engines. Save yourself the hassle of piecing together random parts; this complete kit ensures everything fits and works together properly. It comes with a 12-month warranty too. A must-have for anyone building a mean street or strip engine with multiple carbs.
