This spacer is designed to move the banjo out one inch from the fuel inlet, providing lever clearance for your 6x2 progressive linkage. It adds clearance for the forward-facing sliding rod on each center carb, allowing the sliding rods to pull the front carbs open without hitting the spacer. The spacer is made of media polished stainless steel and features our proven Stromberg superseat seal into S-jet. It fits both single and double banjos. Please note that banjos are available separately.
