Big Block Chevy 36-1 Trigger Wheel

36-1 Trigger Wheel with multiple mounting positions, designed to fit between the harmonic balancer and crankshaft pulley on Big Block Chevrolet engines. This trigger wheel can be used with any VR or Hall Effect crankshaft position sensor to provide your ECU with accurate crank position information. We use a Stainless steel mounting adapter similar to what you are already used to, but provide these in 1/4" thickness, precision cut with powder coating for high RPM stability and corrosion resistance.
