Custom for you

Piston is most critical items to determine your engine performance.Please use perfectly matched pistons to your cylinder bores and heads to achieve your target horse powers. 

Sometimes OE connecting rods have not enough strength to hold the output from your performance engine. And also usually very heavy. We design and manufacture stronger and lighter than current rods for you.

Although the stock crankshaft appears to be highly rigid at first glance, it vibrates in complex ways due to input from the connecting rod and flywheel at high r.p.m., limiting the maximum engine speed. We design crankshafts that are lightweight in unnecessary areas, and same time increase stighness, suppress vibration, and are compatible with high r.p.m.

We can increase the intake efficiency of the engine and increase torque by enlarging the intake and exhaust valve diameters according to the customer's engine specifications. In addition, by changing the material of the valve itself to increase its strength and at the same time reduce its weight, it improves the response at high r.p.m.

We have a wide range of valve springs to choose from depending on the valve and camshaft specifications for your target r.p.m. By suppressing unnecessary valve jumps, you can improve valve response at high r.p.m.
