Two Front Works Shocks The difference between the Black Widow and the G-Series shocks are the dual line on the G-series, other then that, they have the same spring rates and valving. Please allow 2 weeks build time as these are custom built for you. Please give us the weight of the rider and type of riding(dunes, motor cross tracks, etc.) so that our engineers can determine the correct setup. Normal setup is for a plush ride with excellent rebound control. Free Shipping Included!! | |||||||||
