i decided to put a mini spool in the rear, found one on TRAILGEAR for $75. im positive the front is limited slip now because i was trying to pull a log with my sammy, going real slow, only one front tire would spin. but afterwards, i got temporarily stuck n a mud hole and when i was real easy on the skinny pedal, only one front tire would spin, but when i started pourin the gas to 'er, both front tires started to sling mud.
