Chromoly Straight Wall Pins
Left = for Spirolox | Right = for Wirelocks
These are actually the standard pins found in our 3SX Ross pistons. They are rated at 100,000-120,000psi. They measure 2.500" long by 0.866" diameter x 0.125" wall thickness. These are good for mid- to high-horsepower numbers (up to 600-700 hp). If you need replacement pins, these are for you.
