This is a very helpful and hard to find engine oil seal kit for the now 1974 RT360. You get both (left and right) Crank seals, primary drive (Sprocket) output shaft seal, Shift seal, Clutch seal and Kick Start shaft seal. New seals that will seal up your engine perfectly not 40 year old seals. You and your bike will be happy! This is one of the best sets out there. Teflon lip on crank seal where originally used..most cheaper seals do not have this. We only sell the best! Top quality aftermarket item. This is an essential item if you are riding, racing or restoring one of these cool vintage Yamaha's! That's is it! Back to the garage for us! We ship worldwide. Thank you, and look forward to doing business with you!
