Flatout Suspension GR50-PRO

Our Flatout Suspension GR50-PRO is the pinnacle of our rally suspension variants. Most notable features are the huge 62mm body (same diameter as a soda can) with a 50mm insert. The PRO model also features reservoirs on front and rear and high-speed and low-speed compression damping are independently controlled.

Due to the complexity and option of this suspension, we do not offer an off-the-shelf version. You can choose your rates F/R, travel F/R, and spherical bearing top plates or camber plates. These are only offered for select models. Please use the contact form below if you are interested in purchasing.
