Lotus Esprit / Excel Triple V Crank Pulley - manufactured from billet aluminium and hard anodised for proper wear resistance. This can be used as a standard replacement part but the design also includes the facility to mount a crankshaft trigger wheel to allow aftermarket ECUs to be used for fuel injection or mapped ignition. There is a shoulder on the rear with three treaded holes to mount a steel “missing tooth” trigger wheel. We can supply a matching 36-1 trigger wheel and a sensor mounting kit if required for an additional cost.
