Distributor for 1975-1996 Ford F-150 & More - MSD 83521

MSD 83521 distributor for the 1975-1996 Ford F-150 V8 5.0L and other vehicles is a ready-to-run upgrade for bulky DuraSpark and breaker point systems. As an MSD Ignition distributor it carries its own ignition module and does not require an MSD Ignition Control.

• Built-in module produces a 7.5 amp single spark through high rpm
• CNC machined billet aluminum housing and base, smaller in diameter to accommodate induction setups and tight engine compartments
• Maintenance-free magnetic pickup and precision reluctor create stable trigger signals through the rpm range
• Polished steel shaft is QPQ coated and guided by a sealed ball bearing
• Nylon pads ensure smooth operation of the advance weights, and the weight pins are staked and tig welded to the plate
• Built-in rev limiter and a vacuum advance canister for improved economy
