A pre-stressed Welded Counterweight Crankshaft will smooth out your engine's total power range. The welded counterweights help prevent "whipping" and upper RPM vibration due to normal 4 cylinder operation. The Welded Counterweight is a good investment for high performance or long haul street engines. A counterweight engine runs smoother, produces more power and lasts longer than similar non-counterweighted engines.

Each Welded Counterweight supplied by CB is precision indexed and ground to assure perfect alignment and straightness. Each bearing journal is re-ground and radiused to exacting standards. The assembled counterweight unit is shot peened prior to grinding and micro polishing. The stock stroke (69mm) welded counterweight is your assurance of a strong bottom end and non-harmonic mid-range performance.

NOTE: These are drilled for 8 dowel, but dowels are sold separately (#1415, #1418). These Counterweighted Crankshafts are cut UNDERSIZED, so ask a salesperson which bearings you will need.
