Perris, CA – PRW Industries Inc. has developed extra-strength (Custom 4135 Chromoly; rated at 200,000 psi) damper bolts. These fasteners are designed to lock the damper in place, while the damper absorbs the kinetic energy that results from crankshaft torsion and twist. Each damper bolt is complemented by a 0.250” thick wide area washer of similar equivalence and strength. The balancer bolt features a 12 point head that is taller in design to accept a deep socket; minimizing the possibility of stripping under torque loads. Applications include all Ford Small Block, Big Block, FE & Modified Engines, and all Pontiac 287-455 engines.
