Engine Mount Motion Restrictor

To prevent excessive motion and/or shear failure in the left engine mount, a bolt may be put through the mount as shown.

  • Drill a 7/16" hole all the way through the mount where indicated.
  • Insert a  7/16" x 2"L bolt through from the engine side.  You may have to "screw" the bolt through the rubber portion where it contricts because of non-perfect drilling.
  • Install a stover (locking)  nut on the chassis side so that there is about 0.010" end play.  For competition you may want to tighten the nut to zero clearance.  No washers are necessary.
