Wiseco Piston Oil Rail Supports

5.0 out of 5 stars 1 Customer Reviews

Wiseco piston oil rail supports are effective in applications where the piston oil ring groove intersects the pinhole. They can be used only in pistons that have the groove machined 0.030 in. wider than the oil ring. They're manufactured from spring steel and install against the bottom sill of the oil ring groove. Available in different bore diameters to suit your specific engine's needs, Wiseco piston oil rail supports will keep your pistons working smoothly throughout the entire operating range.
