The JE Oil Rail Support is a piston oil-rail retention component that prevents the oil ring rails from rotating or spiraling off pistons with short compression distances. JE’s exclusive locking detent keeps the rail support gap at 90° from the pin bore opening. Supplied per piece, it fits bores between 3.424 and 3.464 in with 0.122 in radial depth.
