First time poster here, as I was lucky enough to just get a free Mule. Long story, but it is a 1996 model 2510. I am in the process of making it drivable (replacing 2 u-joints, CV joints, brakes, wheel bearings, and re-welding one of the front differential mounts). My question is this: how can I tell if my Mule already has a lift kit? It sits relatively level front to back. The rear spring shackles look new and are 4" eye-to-eye. The front springs look to be stock and there are no spacers. I will be buying at least heavier duty front springs, and will buy the Highlifter kit if their rear shackles are longer than 4". Anybody know the length of the Highlifter shackles? I am also planning on plowing with this, any recommendations on brands? Sorry this is so long, but thanks for the help.
