Mazworx SR20 Crank Pulley Bolt - 12309-SR20
Made it house at Mazworx out of 4140 Heat Treated Chrome Moly with a Black Zinc coating. The classic crank pulley bolt has a separate washer. The P12 SR20VE started coming as a bolt with integrated washer. So we developed ours off the integrated as a flanged bolt. (torque to 140ftlbs.)
