These distributors feature an adjustable Sync Pickup to match your ECU's requirements (up to 60° BTDC). The pickup uses a powerful rare earth magnet for strong trigger signals, and the wiring is routed through a weathertight connector for a positive-locking, sealed connection...it never requires adjustment and is extremely accurate.
Each distributor housing is CNC-machined from a billet of 6061-T6 aluminum for strength and durability. Each distributor has a small diameter cap to fit in tight engine compartments, and there is an adjustable slip collar on the Chevy models so you can accurately set the distributor's installation depth in the engine. An oversized steel shaft spins in a sealed ball bearing at the top of the housing and an extra long sintered bushing at the bottom adds even more stability. To trigger the MSD Ignition, a high-output magnetic pickup is signaled by an exact reluctor.
