SKU #: BD-1030060 BD-Power 60# Exhaust Valve Springs Kit 89-98 5.9L 12 Valve Dodge Cummins 1030060

BD strongly recommends installing heavy duty (60 psi) exhaust valve springs with their exhaust brake on 1988-1998 12 valve Dodge Cummins for optimum braking power. The factory exhaust valve springs are not rated to retain the pressure the BD puts forth on the springs.
