daking Posted December 16, 2015 Share Posted December 16, 2015 First, Nice truck. Looks very well thought out and built. Sand. I love it. You don't need to worry about the filter, unless your hitting "Talcum Powder type sand". That will shut you down quick. I hit that stuff once, stalled the engine. The cone filter "imploded". Nothing got into the engine. That was in my RAM. Try to lighten up the front end. Swap the winch cable for synthetic. I'm in the sand alot, and my build shows it. I relocated some heavy items to the rear, like Battery, Spare Tire, Air Compressor system. You want the front to be as light as you can, so the tires don't plow a small hill of sand. Bring an air compressor. You want your tires at a very low pressure. Example, I'll run 5PSI rear, 8PSI front. Different tires will reflect the PSI you should run. The current tires on my jeep have hard side walls, so need lower PSI to "float" the sand. I usually let air out, then look at the tire. I'm looking for a decent "Bulge". You want to increase the foot print. (bring valve stem removal tool and extra stems, or buy defoliators. Although a stick or rock will work too ) If you do run a low pressure, be aware that it is much easier for a tire to pop of the rim. Try not to turn sharp at speed. Believe it or not, less aggressive tires are better for sand. In fact, normal wide street tires running with a very low PSI will do much better then aggressive tires. The aggressive tire will actually dig down when wheel speed is applied. Obviously, if you got the HP and ability to get excessive wheel speed, then a more aggressive tire may be needed. If you have soft rear springs, or lift blocks you may notice wheel hop. Good solution is new springs and or track arm. However a quick solution is spring clamps on the front of the leaf pack. Clamp them the the over load. Even if you don't have or notice wheel hop, adding the clamps will improve your sand experience. Driving in sand will put more stress on the engine. Watch your temperatures. bring extra water. Here is my 392 HEMI RAM in the sand (It has a 620+HP 426 now) Have fun! Link to comment Share on other sites More sharing options...

I never thought about lightening the front end but id like to get a synthetic cable anyway for safety reasons. The 5 or so times I've used my winch it always scares me a little bit.

Crash Posted December 16, 2015 Share Posted December 16, 2015 Even stock XJ/MJ heeps are fun in the sand. Keep momentum. LSD or locker in the rear goes a long way. But air down and you will get better traction. And have fun! Link to comment Share on other sites More sharing options...

My uncle brought his 51 willy's last year and that thing was a hoot until he smashed oil pan Link to comment Share on other sites More sharing options...
Pete M Posted December 16, 2015 Share Posted December 16, 2015 light weight, near-flat tires, and a means to hook up a strap are really all you need. . :MJ 1: . I would actually give consideration to leaving the bumper and winch combo behind as long as you can retain a strong strap point.. Link to comment Share on other sites More sharing options...
Tj1 Posted December 16, 2015 Share Posted December 16, 2015 The last time I took my TJ out on the dunes the trans cooler line rubbed a hole and was leaking on my exhaust. black tape and zip-ties till I got back to my trailer. Ive ruined a u-joint before from it having too much grease in/on the caps and sand found its way in. Low tire pressure for sure, if you start wheel hopping take a little more air out.
