think about it this way, a jeep weights about 3500 lbs, and for that you need an 8k lb winch due to dual sides pulling also known as newton's third law. (remember "every action has an equal but opposite reaction" from physics) basically when you pull against tree to pull yourself out youre gonna be pulling with about 3500 and the tree will be "pulling" just as much, equaling to 7000 lbs of force, however when starting the initial pull, because gravity has been pulling down on you its gonna be especially hard to start (remember being a little kid and trying to push a big drawer and having to push really hard initially but then it was smooth sailing? also being newtons first law. by using a snatch block (pulley) youre not DOUBLING your pulling strength (physics law of conservation of enery) basically, with a normal set up your machine will pull a rate of foot per foot. while with a pulley, while there is less load on the machine, it will pull at a rate of foot per half a foot. basically doing the same amount of work in the end. return the winch, save your paychecks and get a smittybilt xrc8000 winch GOOD LUCK AND HAPPY WHEELIN!

Facepalm at ^ and his physics lesson.

This just took my physics to a whole new level! Lol but anyway thanks for the advice

There has been many times (once last wk) when I had to either pull someone,or myself(doesent happen much being now locked front & rear) that the mud creates a suction,sort of like when you step in mud & your shoe stays but you pulled your foot out.It made my 8k Warn work really hard,put a lot of strain on my batt.I actually got a really good Sears batt after that.A 5k winch wouldent have done the job,Im sure.

Enjoyed the read but that's not how winches are rated their rated by line pull.

Yes, the forces are in equal and opposite directions, but that doesn't mean there is double the strain on the line. If you want to get technical the winch is just creating tension (Ft) on the line between the anchor point and the jeep. That tension is both acting on the jeep and the anchor, but since the anchor is in theory unmovable, the jeep moves. All newtons law is saying is that the force of the winch pull is applied both to the jeep in one direction and the anchor in the opposite.

Just let him sit in his physics world by himself.

sorry jherrington, I know how much of a physics genius you must be and forgot to check with you on it. next time I need some help with physics i'll be sure to come looking for you in a jiffy!

Mark twain said it best. But, I just thought maybe you shouldn't lecture someone on a subject that you aren't comfortable with.

Maybe a silly question but why a yellow & blue wire? Also they dont look like a thick enough gauge wire,not sure which is batt positive for a lot of amperage.Maybe its just the pix?

Yea the yellow and blue wire are pretty thick and that's the only place that I could run them through
