I've got the ford lsd..... and 4.10s I've also got a curb weight of 6400lbs... The fat boy will hold his own, even in 2wd
6400? dang. and your not even a screw! mine is almost 6 I believe. I do have a steel bumper, roof rack and bedcage. I have 4.11s and detroit mechanical. Ive pulled my buddies pathy around with quite a bit of ease. I think its mainly a v8 to v6 thing and I also have a lot more weight than he does.
Lol Yeah, she's a heavy beast. That's including the tool box full of chains, tools, my jack, and a full 36g fuel tank.
