DirtyBike 500 to 550 LBS Shock Spring for Surron Ultra Bee

Stiffen up that rear end! Use this stiffer shock spring to firm up your ride. 

Available in 500lb and 550lb springs.

Note: Springs over 600lb should not be used on the stock shock. The higher spring rate will overwhelm you shock and will not have enough rebound dampening to function properly.
