Prevent oil leaks and maintain optimal engine performance with the PEVAST 2-Piece Crankshaft Seal Kit. Designed for FD-Series engines (FD590V, FD611V, FD620D, FD661D), this set includes both seals needed to replace worn or leaking OEM numbers 92049-2112 and 92049-2110. Crankshaft seals are critical for containing oil within the engine block. When they fail, oil loss can lead to overheating, performance loss, and costly engine damage. This PEVAST kit provides a precise, durable replacement made from high-grade nitrile rubber that resizes heat, friction, and oil degradation over time.
