MSD is proud to offer a new Pro-Billet Distributor designed to handle the rigors and harsh racing conditions of late model, modified, and off-road racing. The new distributor was designed with input from top racers and engine builders in circle track competition. The new Pro-Billet Distributor has been precision engineered to feature the highest available technical design in its class. Starting at the top of the distributor, a larger diameter distributor cap is securely bolted to the billet aluminum housing. The extra width prevents the chance of spark scatter during high rpm racing. Under the injection molded rotor is a billet steel Reluctor and proven magnetic pickup assembly. The steel Reluctor offers the material and strength required to be modified for advanced cylinder-to-cylinder timing orders. These components are parylene coated to prevent corrosion and the timing is locked-out for a solid signal from idle to redline. Inside the CNC-machined housing, a sealed ball bearing assembly guides a .500 in. shaft that receives a friction reducing QPQ coating. Mounted to the base of this shaft is an oversized (+.006 in.) bronze distributor gear to ensure the proper mesh with the cam gear.
