Enforcer manufactured Zero Drag Seals. The purpose of a Zero Drag Seal is to limit the interference between the rubber crankshaft seals and the crankshaft on a Zenoah G230, G231, and the G260 Zenoah engine. By reducing the crankshaft friction these seals will boost your engines usable RPM range by as much as 200. This is the perfect low dollar investment that will yield that extra edge for the serious competitor. Zero Drag Seals are very easy to install without having to split the the crankcase. You recieve two seals per kit, one for each end of the crankshaft.

NOTE: Zero Drag Seals are not intended for clutched engines!
By using Zero Drag Seals, a slight amount of additional air intake can leak through the seals, resulting in a higher engine idle. Therefore, they are not recommended on clutch type engines.
