HOME » Crankshaft Service








A trued, welded and balanced crankshaft will run more efficient, create more power, and run smoother. When the crankshaft is true, the surrounding component life expectancy is also better.

    Basic Crank Service: $480.70 (2007 and Up Parts and Labor) / $600.60 (1999-2006 Parts and Labor)

  • Pressed together Harley-Davidson Twin Cam cranks are often out of true even as new. Over time they can move and become even more out of true. This can cause excessive vibration, less power, and damage to the oil pump and cam plate. Revolution Performance Basic Service can fix this common issue and help to prevent it from happening again. We true the crank, insert a plug, and then weld the crank pin to help prevent movement. Price includes crank labor and crank pin, connecting rod bearings, wrist pin bushings, and pinion shaft race.

    Crank Balancing Service: $800.70 (2007 and Up Parts and Labor) / $920.70 (1999-2006 Parts and Labor)

  • When adding big bore pistons, especially extremely big bore pistons like our Monster Big Bore Kits, the increase in reciprocal mass (rods and pistons) dictates balancing the rotational mass, the crankshaft. The crank is completely disassembled and trued. The crank is then dynamically balanced on our ultra-precise Sunnen DCB750 dynamic balancing machines. A plug is then inserted and the welded in place, so the crank will remain balanced and true. A properly balanced crank will make more power with increased reliability. Price includes crank labor and crank pin, connecting rod bearings, wrist pin bushings, and pinion shaft race.

    Bullet Proof Crank Balancing Service: $999.95 (1999-2007 Parts and Labor)

  • The ultimate American V-Twin crankshaft service with new Ultima H-Beam Rods for the smoothest, most reliable Twin Cam crank assembly. Heavy duty Monster big bore pistons and Ultima H-Beam Rods increase in reciprocal mass of the engine and this dictates balancing of the rotational mass, the crankshaft. The crank is completely disassembled, trued with new Ultima H-Beam Rods are installed. The crank is then dynamically balanced on our ultra-precise Sunnen DCB750 dynamic balancing machines. A plug is then inserted and the welded in place, so the crank will remain balanced and true. A properly balanced crank will make more power with increased reliability. Price includes crank labor and crank pin, connecting rod bearings, wrist pin bushings, pinion shaft race, and Ultima H-Beam Rods.

NOTE: Balancing services require piston weights (including pin, clips and rings). If these weights are not provided, it will cause a delay in the work and extend the turn around time.
