I have a new uforce 1000 and I have some questions. I just added an RJWC exhaust from MSC to it, will that cause any potential motor issues or am I fine to run as is? I am also stuck between getting 4inch portals, 15 inch rims, 33 inch tires, OR a 2 inch lift, 15 inch rims, and 30 inch tires. Any suggestions? I am also planning on purchasing the stage 3 mud clutch kit from MSC, think thats a good purchase?
