The special truss shape enhances the durability and makes ultra-lightweight pistons.
A squish area allows for high-rate combustion.
Connecting Rods
The connecting rods were designed specifically for this kit.
Engine modifications are minimized.
Crankshaft Stroke - 99.0mm
9.0mm stroke without bore size change is incomparable.
Billet Crankshaft
The vibration generated from the V6 engine is reduced to a degree that is not annoying by precise balance adjustment. (The included parts must be used together)
The structure was designed to reduce the load on the metals so it can withstand the increased load to the main metal due to higher torque.
High-efficiency heavy metal made balance weight reduces the weight and achieves high engine response.
Compatible with Stock Bore Size - 95.5mm
The bore size is the same as the stock size to maintain the engine block rigidity and the ideal heat conduction for optimal engine performance.
Modification of liner is not necessary so the cost related to this liner modification can be saved.
Special Oil Jet
A special oil jet to cool down the pistons to the optimum level is newly designed.
