I bought a Kmod skid and raptor shocks last year for my M sled, I was impressed at how well this set up worked over factory, I had a 10 M8 all stock suspension and man it was night and day difference, seems like everyone gets on here to bash or complain I just wanted to give some positive feedback for these two companies, both have helped me alot and went above and beyond my expectations. Kevin at K mod is a great guy to deal with, answers the phone or calls me back right away, took my 2011 Kmod rails in on trade for new ones which he didnt have to do, very happy with the service and the suspension is awesome.. Jake at Raptor shocks has been great to deal with, I bought front and rear shocks last year and had bout 400 miles on them, I had to change the shocks a little for the narrow front end on the PC, talked to him and he said to send them all in and he would set them up for the pro climb with the narrow front also they had a couple updates and new progressive springs/ different retainers, he went through them (all 4) made sure they were good to go, did all that and only charged me the freight to send them back...definately top notch service... and awesome shock package.. both have said if i need anything when im out riding or setup help to call... pretty hard to beat that for a guy who bought one skid and shock package.
