Product Information

Product Details
Part No. 83663
Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)
The entire housing is CNC-machined to exact tolerances for incredible strength (not to mention cool looks). For improved lubrication there is an extra oil tract machined into the bottom of the housing that delivers oil directly to the cam and distributor gears. Inside, a polished steel shaft receives guidance from a sealed ball bearing and an extra-long sintered bushing adds stability. This 0.500" shaft also receives a QPQ coating for increased friction reduction and corrosion resistance.

Product Features:
  • Drop-in billet replacement for GM distributors with the small cap and external coil
  • Factory style ignition module accepts factory wiring
  • CNC machined billet aluminum housing and billet aluminum base
  • Magnetic pickup and precision reluctor create stable trigger signals throughout the rpm range
  • Oversized steel shaft is QPQ coated and guided by a sealed ball bearing and an extra long sintered bushing
  • Special oil tract improves lubrication to the distributor and cam gear
  • O-ring seals can be added to modified blocks to improve oil pressure control
  • Supplied with late model distributor cap and rotor
  • Legal to install in all 50 states
  • Marine UL Certified
