MSD Chevy Crab Cap Crank Trigger Distributor

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.

Key Features

• Ultra-low-profile Crab Cap design allows for maximum clearance in tight engine configurations
• CNC-machined billet aluminum housing provides superior durability and stable operation
• Dual optional O-rings at the base improve overall engine oil pressure control
• Integrated oil tract bleeds lubrication directly onto the gears to prevent premature wear
• Adjustable slip collar design accommodates engines with modified deck heights

Fitment

• Chevrolet Small Block V8 Engines
• Chevrolet Big Block V8 Engines

Note: Must be used in conjunction with an external MSD Crank Trigger and an MSD 6, 7, or 8-Series Ignition Control module; includes a bronze distributor gear which requires specialized camshaft compatibility considerations.
