4L in soft deep sand

[Powelligator]

So, my question is...trying to pull a trailer through deep sugar sand, are you better off running 4Lo with lower wheel speed or 4Hi and keeping the wheel speed up. I don't live near deep sand but I have on occasion needed to cross part of a recently plowed field. Never with a trailer on though.

The first rule of deep sugar sand is to dump all the air pressure out of your tires, you want be be around 5 psi if you're pulling a tailer. Then run in 4-Low, don't start in first gear and gas it if you need to but you shouldn't need high range unless you've disconnected the trailer and are, at that point, just blasting around having fun.

Looks like an air system is certainly on my birthday or Christmas list. I totally should have aired down. I kept my revs well below redline. My guess is that the 25MPH "limit" is aimed toward all Jeep models regardless of TC and diff ratios.

Air down in 4h and keep up good forward momentum, and keep traction control off.

Just a reminder, for any of you just reading this with the 8 speed auto.

With the automatic 8-speed, unlike the M6 like the OP, if you want maximum ALL nannies off goodness, you must ALSO shift into manual shifting mode.

Many of you knew this I'm sure. I just wanted to make sure everybody is on the same page moving forward.

depending on tire size Viair makes some good portable compressors. i believe mine was a 400P but the newer one is worth the extra few bucks. has the pressure switch built in to shut the compressor off between tires instead of just staying running. both are good for up to a 35" tire. if you plan to get up in the 37" or bigger tire get your self a dual arb or similar style. pay once cry once. I just installed a dual compressor into the jeep so its always there. love the arb under seat bracket.

Just as a comment, you can't rev the engine above redline with the gas pedal no matter how hard you try. If you hold your foot to the floor it will reach the rev limiter and not let it get higher than that. The rev limiter/redline on the tach is set at a pretty conservative point. You could put the thing in 1st gear and plant your foot to the floor and run the Jeep for an hour non-stop and it shouldn't blow up or anything but rather the engine RPM would just be bouncing off the rev limiter.........not saying you should do that or I recommend it, but that is the way it works. I worked in automotive testing for 12 years and manufacturers did do testing similar to this that most people would never dream of doing to their vehicles.
The 25 mph limit likely has very little to do with the RPM level of the engine, but rather they are saying if you can consistently run over 25 mph you really shouldn't be in 4 low.
