Description

The JE Pistons GLS15 is a piston oil rail support ring spacer designed to prevent the oil ring from protruding through the wrist pin opening. This is essential in applications where the pin bore intersects the oil groove, such as those with short compression heights due to large strokes or long rod lengths. The GLS15 is specifically designed for pistons with a groove machined 0.030 inches wider than the oil ring and has a bore range of 3.331-3.369 inches with a 0.200-inch radial wall.
