This is a complete set of 8 Pistons with Clips, Wrist Pins & Pre-Installed Premium MAHLE Rings, featuring a Keystone Style Top Ring for Maximum Compression Retention. MAHLE 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 over Hypereutectic material 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 MAHLEs ring groove inserts make a better piston than a forged material which does not hold the insert very well. MAHLE uses Eutectic material so they can install high strength ring-land inserts into the piston grooves for longer life. MAHLE 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.
