Rebound Adjuster

With a range up to 12 positions adjust rebound with a single turn on the knob on the top of your coilover. Defaulting at 6 and on the adjust knob you can see a + or – and when you turn + it will stiffens the reboud.

(NOTE: the rebound adjuster opens or closes a small bleed hole , this restricts the flow of fluid . Each click will have an effect on the handling characteristics so do not adjust more than 1 or 2 clicks at a time).

Monotube Design

Monotube design - with performance in mind. Inside the monotube is oil and nitrogen that are seperated by a floating piston. With it being a mono instead of Toyota's OEM dual design it allows for a much larger piston, increasing damper performance and sesntivity felt by you, the driver. Produce more grip, have more control, and get more feedback with the monotube design.
