GMC G3500 Engine Internals

The crankshaft position sensor provides a signal to the engine control module (ECM) or ignition control module (ICM) pinpointing the exact location of the crankshaft for spark and fuel injection timing. The electronic control unit (ECU) will also use the signal to identify specific cylinders for misfire detection and cylinder deactivation on some applications. The crankshaft sensor can be found in-line with the crankshaft either mounted to the engine block, or near the flywheel, or the crankshaft damper pulley.

Product Features:

• Application matched component to ensure the system can be returned to like new condition.
• Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.

As the crankshaft flexes and twists, the balancer absorbs incredible amounts of kinetic energy. To ensure that the balancer is locked in position, ARP has developed these ultra strong 200,000 PSI bolts that let you exert maximum clamping force. Special features include 1/4 Inch thick, wide area washer and an extra tall 12 point head that accepts a deep socket and eliminates the worry of stripping the head.

Far superior to any other main bolt kit offered for use in competition engines, ARP main bolts are designed to meet the exacting standards and demands of professional engine builders. Forged from 8740 chrome moly, all bolts feature generous under head radius and rolled threads for the utmost reliability. The threads are rolled after heat treating, which makes them about 1000 Percent longer fatigue life than most main bolts, which are threaded prior to heat treating. Available in the popular High Performance Series, which, at a nominal rating of 180,000 PSI, is a premium replacement for OEM fasteners, or the 200,000 PSI nominal rated Pro Series, application specific main bolts with reduced wrenching head and are designed for use in competition applications. Parallel ground, hardened washers are included with each kit.
