FEATURES: Special head liners for Directed-Coolant Bushings, to direct coolant from a drilled manifold passage to the holes in the bushing's OD wall. Head liners provide positive resistance to heavy axial forces. Important: always order the liner length listed in the table, for proper hole alignment. DC bushings must be the same length as their liners, while DCCH bushings must extend beyond their liners to the next standard length.
