This is a complete set of 6 Pistons with Clips and Wrist Pins. Pistons: 1. Ni-resist top grooves to control groove wear. 2. Balanced Set of 6 for smooth engine operation. 3. The M124 Piston material (used in these pistons) is a highly evolved Eutectic material, which contains approximately 12% silicon for excellent strength and excellent thermal expansion properties. For diesel engines, the Eutectic material is chosen because it bonds better with the ring land or ring groove inserts used to strengthen and better support the piston rings in high performance/ high load diesel applications. The Eutectic material with uses ring groove inserts to make a better piston than a forged material which does not hold the insert very well. Piston Pins: 1. High strength steels meet structural requirements to prevent pin breakage or deflection. 2. Case hardened to provide long lasting wear surfaces. 3. A high degree of dimensional and surface finish control are the final requirements for strength and long life.
