springs are 400 an end and the hanger and shackle kit is 275 shipping included on the hanger and shackle kit but not on the springs. It is super simple to cut off the ifs and weld on the hanger and drill the frame for the frame tube!! I use trail gear shock hoops and get shocks from them as well cuz they are cheaper then I can make the hoops
IceMan2989 I have never put the kit on an r50 since they are a sub frame I dont think that if would work well for you?
