Dunn Single Hemi Mag Drive

*** IN STOCK SHIPS TODAY *** RBS has found this to be hands down the finest single Hemi mag drive for racing when using BAE, AJPE or Veney fuel heads on alcohol. Many times when running Fat or Muscle heads the racer must run an offset or angled mag drive but typically when running fuel type heads on alcohol a straight mag base is best suited for fit and the budget.

Housing is made from billet alum. to provide superior strength against the dreaded tire shake and will hold the biggest magnetos with no problems. The oil pump shaft is made from a billet steel material and the shaft diameter is .480" between the bronze gear and mag base to prevent shaft twisting allowing timing spikes.

The billet alum. housing is O-ringed to prevent oil leaks and the mag drive uses a contained thrust bearing to control gear movement allowing the use of different engine blocks and not causing any problems. This drive also has one more unique feature and it is the Dunn cross magneto coupler. It has four locating tangs that interlock into one another creating a perfect fit between the two allowing minimal impact to the pulsing magneto.

This drive fits all KB, BAE, TFX, JP-1, Indy and Mopar steel or alum. blocks raised cam or standard cam location and fits all MSD or Mallory magnetos. RBS can also supply billet mag clamps, billet mag claws, magneto supports and stabilizers.
