MSD Chevy Crab Cap Crank Trigger Distributor

The MSD Chevy Crab Cap Crank Trigger Distributor is engineered specifically for high-performance racing engines with extremely tight clearance constraints, such as those equipped with tunnel rams or blowers. It delivers exceptional ignition accuracy under severe operating conditions by relying on an external crank trigger setup while utilizing a low-profile crab style cap to fit restricted engine bays.
