OK, just got my OFF-ROAD Design greasable bushing kit for my front and back. Have not installed my suspension from BDS suspension because I have been waiting for my goodies from OFF-ROAD and HILL. Question to you all is can I grove my BDS urethane bushings or should I use the ones that OFF-ROAD gave me. I like the Blue bushings that BDS has in their kit. What do you all think. Are the OFF-ROAD bushings difference besides their groves for the grease or ????
