Three jet/con-rod combinations are offered - pick according to your build target, as larger jet sizes are generally paired with more aggressive head/cam work. Con-rod length affects piston deck height, so match the option to your cylinder/piston setup rather than mixing parts across combos.

Crankshaft replacement is a full engine teardown job for a qualified mechanic, not a bolt-on part. Package includes the crankshaft with the con-rod length for the chosen combo; bearings/oil seals inclusion is Not verified - confirm with the seller if needed.
