Supercranks

We have assembled racing crankshafts to specifications as close as .0005, We DO NOT use jigs to assemble our crankshafts like others.  Our cranks are all stress relieved and assembled by hand.  Then crank indexing and trueness are measured on a ISO 9000 certified granite table then welded and re checked.  

We also offer ultra high speed light weight hybrid silicon nitride (ceramic) bearings.

As you can see, stock connecting rods may work well on a weed whacker but definitely didn't work well on this High Output Jet ski engine
