The MSD Crab Cap Distributors are built specifically for racing engines with almost no room for a distributor due to tunnel rams or blowers. The distributor is equipped with a special low profile crab style distributor cap to allow it to fit in extremely tight areas.
The housing is precision machined on a CNC machining center producing exact tolerances as well as incredible strength. Other features include two O-rings at the bottom of the housing that improve oil control by preventing oil pressure loss. Also, a small oil bleed hole located in the base sprays oil on the distributor and camshaft gears to prevent excessive wear. Since this is a racing distributor, there is an adjustable slip collar to make up for engines that have had the distance between the mounting surface and the gear modified.
