Ford distributors present a challenge when changing the distributor gear due to their pressed fit, the need to cross drill the distributor shaft and set the gear to a specific height. MSD now offers Ford distributors with steel gears for use with hydraulic roller cams. We've taken the trouble out of the mix with our line of popular Ford distributor applications that come with a steel gear installed ready for hydraulic roller cams. Whether you're working with a crate engine or building your own combination, MSD has the performance distributor ready. In the world of modern engine design, it's hard to beat a hydraulic roller camshaft for all-around performance. It's crucial to match the distributor gear with the cam material to prevent premature failure of the cam or distributor gear which can lead to engine damage.

Features:

  • Polished steel shaft is QPQ coated and guided by a sealed ball bearing
  • Steel Gear Installed
  • Easy-to-adjust mechanical advance with supplied springs and stop bushings
  • Mechanical advance assembly can be locked out for crank trigger systems
  • Advance weight pins are staked and tig welded to the plate
  • CNC Machined Billet Aluminum Housing and Billet Aluminum Base
  • Nylon pads ensure smooth operation of the advance weights
  • Maintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the rpm range
  • Advance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reduction
