As much as an instant 300 RPM boost!

Precision-machined inserts that press into the existing front & rear crankshaft seals. They are made to work in conjunction with the standard crank seals. They fit over the crankshaft, and are located between the seal and the crankshaft.

Zero Drag Seals reduce drag on the crankshaft, creating a smoother surface while retaining the crankcase seal. Installing Zero Drag Seals helps the engine work less reducing wear and tear - while improving RPMs. The improvements are incremental (relatively small), but are part of the process of achieving peak performance.

Simple to install - an easy upgrade for your engine!
