The Allen Screw is made of Titanium Grade 5 6Al4V cetified by U.S.A derivation. It has a total length of 8.5mm of which 6mm are of thread and a protrusion from the crankshaft of only 2.5mm in order to eliminate collisions with the tank in case of excessive flexion of the chassis.
The new geometry makes it possible to eliminate any rubbing between the bearing / bell, so as to reduce the operating temperatures of the whole assembly, furthermore the outer diameter protects the bearing from dust and foreign bodies.
Particular attention has been paid to the hexagon which is clearly concentric and precise. It can be used with any engine and mounted on all 1/8 Buggy models. The weight is of 0.4g
