What is a custom driveline?

These shafts are being increasingly used in the marine, automotive, commercial, and defense sectors. Because of their unique combination of capabilities, they are often used in the most specialized and demanding fields.

All metal shafts will eventually twist slightly from the constant twist caused by torque. The shaft ends can become out of phase over time and vibrations begin to wear down components. A custom driveline on the other side has an almost perfect elastic memory. Therefore, they cannot be permanently twisted. You can find the best custom driveline via

All driveline whip as RPM increases. This bending creates vibration and lateral runout at a specific speed, which is unique to each type. This vibration can cause drivetrain failure at the transmission and rear end. Custom drivelines have a much higher "critical speed" than similar-sized steel and aluminum shafts. Shaft whip vibrations are virtually eliminated by exceptional harmonic damping and low lateral stiffness.

Driveline vibration can cause a reduction in RPM. Metal drive shafts can experience harmonic whip in racing situations, which limits usable RPM and forces them to operate the engine at a lower rev limit. The custom driveline allowed for a 1000 RPM increase in engine speed, allowing the engine to operate at its' peak power. 

All drivelines will twist to some extent when torque is applied. The torsional spring rate is the measure of resistance to twisting. The torsional spring rate of the custom driveline is about half the steel's and a little less than that of aluminum. A lower spring rate means less driveline shock, less stress on other components of the drivetrain, and increased traction.
