Crankshaft Trueing and Welding

The Crankshaft is absolutely the “spine” of your power-plant. It is the core part of a 2-stroke engines design. It has the most stress put upon it out of all the other components. To be clarify, the lower Connecting Rods especially! The best crankshafts are the ones that are built using quality components and have been assembled with pride and exacting tolerances. Crankshafts that are trued by the “supporting on centers” method some feel is the toughest test to pass! Then massaged by only very experienced and prideful pros. These cranks are the ones that run the longest, rev the highest, and produce the least vibrations. They also eliminate exhaust studs breaking in 587s, 657s and 717s! No mystery! It is usually due to harmonic vibration that is caused by the Crank assembly not being anywhere near “SPOT-ON.” We true and weld the best cranks to be had. We have found some need no welding at all.  Stroker are Cranks available upon request in billet only. From the lower-cost remanufactured units, OEM remans, to our full Race-Prepped Cranks.
