Variants & Setup
Jet size sets how much oil reaches the cylinder/piston for lubrication and cooling; smaller jets restrict flow, larger jets increase it. Correct jet choice depends on bore size, compression and your overall tuning setup - there is no single "correct" size for every build, so confirm with your mechanic/tuner before choosing.
Installation & Package
Fitting this crank requires full engine case disassembly and should be done by an experienced mechanic. It must be paired with compatible bearings and oil seals matched to your case. Package includes 1x crankshaft complete set as shown; additional bearings/seals are not confirmed included - check with seller first.
