I want to change out the stock K-member for either the maimum or the UPR. I have the Maximum rear grip pack (panhard bar, Torque arm.....). The MM is very expensive 1700 with instal (500). If I went with the UPR or comparible what would anyone recommend. My concern or assumption is that these suspension kits are engineered to match and balance (center of gravity) and if I choose a different set up would it really matter. The UPR as I understand it is ~700. (need to follow up with what that really includes). Suggestions...........................
