Product Details
This is a JE Pistons Oil Rail Support, designed for pistons with bores ranging from 4.500 inches up to 4.529 inches. Its main job is to stop the oil ring rails from spinning around in their grooves, especially on pistons that have a short distance between the top of the piston and the oil ring groove. This can happen when the piston rocks in the cylinder, and if the rail spins, it can cause oil control issues.
What makes this JE part stand out is its special locking detent. This feature keeps the oil rail firmly in place, preventing it from rotating. JE Pistons designed it so the gap in the oil rail will always be 90 degrees away from the opening for the wrist pin bore on the piston. This is a unique approach that ensures the rail stays put and maintains proper oil control. The radial depth of this support is 0.203 inches.
