Rear main seal (Modified) 455 425 400 350DX


SKU: 2028M Categories: ,


This rear main seal has a performance advantage over the conventional style rope seal. Reciprocating drag on the crankshaft is reduced significantly for added horse power and torque benefits. The outside diameter is more relaxed with a slightly smaller o.d. size to prevent any warpage on the lip that contacts the crankshaft.
