4AG Adjustable Camshaft Sprockets $216.32 pair
Adjustable Cam Gears are made from the highest quality 6061 T6 aluminum. They are CNC machined to more exacting tolerances than original gears. The tooth edges are beveled to increase belt life. With twelve degrees (both advance and retard) of laser etched adjustments, you can be assured of proper and precise tuning. The inner ring of the cam gear is designed for strength, function, and precision. Stainless steel studs are threaded through the backside of the outer gear. The inner gear is then fastened with stainless steel nuts and lockwashers. This enables an increase in the amount of torque used to tighten the fasteners, with no risk of stretching to the aluminum threads. All chain drive gears have a 1050 steel outer sprocket. All belt drive cam gears are made from 6061 T6 aluminum.

*New design! 4AG 16V forged drill lightweight high-comp piston 83 bore (257g)
Lightweight racing pistons that pursued the ideal shape by fully drilled and machined based on high strength fabricated materials. The use of a pinch taper to reduce the load of a pin boss, and a 3D profile that reduces friction loss even at high temperature and high speed rotating ranges, and even the rich muscles can run the stuff without wasting time, we completed the weight of 273g. Comes with low friction reinforced piston rings and can handle high output and high torque simultaneously.
