- Feature fully boxed-style forging for ultimate strength, minimizing friction, durability, power, and weight reduction
- Full radius dome designs maximize quench while eliminating hot spots that promote detonation
- Internal bracing maximizes durability while decreasing friction in the pin assembly
- Forgings come standard with skirt coating which reduces friction, which in turn reduces heat
- Includes a DLC (Diamond-Like Carbon coating) wrist pin; this technology has been proven and used because of its high resistance to abrasive wear, which extends the service life and reliability under extreme conditions
- Kit includes piston, wrist pin, rings, and circlips
- Made in the USA
