Requires a 60mm long, 25mm diameter crankshaft input, output is to a 22mm shaft, also known as the R type PTO shaft.

Ready to assemble, they give incredible torque at lower engine speeds, and are ideal replacements on go-karts, mixers, pumps etc.

Good for routine engine care
Size: 150 ml, Pack of 1
Definitely not a cure-all for major mechanical problems, but it works well as a preventative step. It helps lessen deposits and keeps the engine running smoothly. I intend to use it regularly as part of my maintenance schedule to keep everything in good shape.
