Just when you thought you coudln't add any more custom tuning to your JLF... It's time for the Paradise JLF Actuators.

This actuator addes 1.0mm to the diameter of the standard JLF actuator.  This shortens throws and allows for easier diagnols. Designed to take the stock spring or custom Paradise springs, aluminum actuators are a great way to tune that stick perfectly.

Actuators come in 0.5mm increments from 0.5 to 2.0 oversize, red, orange, green, and blue respectively anodized for easy identification.
