The MSD crab cap distributors are engineered to fit racing engines that have little to no room for a distributor due to tunnel rams or blowers. Integrating a special low-profile crab style distributor cap, these distributors ensure reliable fitment in exceedingly tight areas. The cap utilizes spark plug style terminals for an improved connection and an outstanding grip to the plug wires. These distributors are designed with a housing that has two optional O-rings at the bottom to prevent oil pressure loss and promote better oil control. They have a small oil bleed hole in the base that appropriately sprays oil on the distributor and camshaft gears to effectively prevent excessive wear.

These racing distributors feature an adjustable slip collar to effectively make up for engines with an adjusted distance between the mounting surface and gear. They also feature an oversized polished steel shaft with a QPQ coating to reduce friction. What's more, the shaft is properly guided by a sealed ball bearing and an appropriately long sintered bushing for proper stability.
