How much would the max sideslope angle able to be negotiated with a D2 be affected by 2" OME? I assume the higher COG would make it more tippy, but if 35 degrees is safe with a stock D2, what angle is safe with the 2" lift? Also, how would sway bar removal affect this as well?

There is no straight answer to that. You can't even make the assumption that 35 degrees is always safe in a stock truck. There are too many factors involved, such as how the truck is loaded, condition and type of the trail and speed, just for starters. - Axel | ||

Assume equal or no loads at slowest possible speeds on a nice repeatable slope, like the ones at LR dealers. Surely there must be some rule of thumb here... John F | ||

assume it's still 35 deg. they can go to nearly 45 stock. rd | ||

Just keep in mind that the real world rarely has engineered slopes like this. I have driven the course at my dealer several times with a 2" lift and sways attached. Quite frankly it freaked me out every time I did it. Now that I am at somewhere around 3" and no sways, I doubt I will be on that hill anymore. My rig would probably do it fine, but the driver would not like it much. | ||

Ideally, you should widen the truck 2 inches for every 1" lifted. I am still trying to achieve this with mine, but come short somehwat: Vertical Increase: 3" Suspension + 3" in tires (29s to 35s) + 2" BL (negligeable) = 6" total lifted COG (assuming) Width Increase: 8" no backspacing wheels (4-2.67 = 1.37) + 10.5 tire (12.5-9.5 = 3/2 = 1.5) = 5.74 in total... Shitty math, but basically I am almost there...given that I deflate msot of the time (-1.5-2" lift), then I win!  | ||

"Shitty math, but basically I am almost there...given that I deflate msot of the time (-1.5-2" lift), then I win!" Nidim....good theory I think, but I have always felt more tippy with deflated tires. | ||

I got almost 3" with My OME setup, and have no swaybars. I am running 32" tires, and I have no problems cornering, negotiating sideslopes, or climbing. As a matter of fact, I like the ride better, and the extra flex, coupled with the CDL lever I installed, makes misty feel much more sure footed. I took the sway bars off one day out of boredom and simply never put them back on. The stiffer OME springs and shocks help, but the truck is stable. I am not going to give you any angles, because that would be foolish on my part, given the variables involved, but I do suggest taking them off one day just to see how you like it. Rob has it pegged. I think my truck could handle the dealer course fine right now, but I also think my oh shit meter is broken, so don't take my word for it. Cheers, Kennith 2001 Disco II | ||

Brian... Deflating does give you a "feeling" of insecurity because the sidewalls are WAY too flexy, but, effectively it helps a lot! A month ago I was wheeling with my spotter/bestfriend in a "practice" run that we are preparing for in December, and we took a nice sideslope in a wooded area...it was all fine and dandy, then at one point the upper front tire got on a rock AT THE SAME TIME when the lower one got into a small hole...and that is where he screamed for the FIRST time in 6 years of offroading! we were not dflated then...He went out and started deflating the upper tires, and then the lower ones, and I drove out of that situation without any drama...basically, after that point I was taking MUCH tougher side-slopes without porblems...tire stiffness is important here, the Simex ETs have 22mm sidewalls, 6 plys and are VERY stiff (a la SXs). | ||

Never assume, just like many people are saying. I have an adventure rack, and a 2" lift and I have been off-road up to 33 degrees. I use the lean-o-meter thing. Which should be used for reference only by the way... But it helps, and it is better than your gut feeling until you have a lot of experience in how 20 degrees and higher feels. I would say that 20 degrees is the final truely safe angle. Above that, if you are going too fast, hit the wrong bump, at just the wrong time, or with the wrong amount of stuff on the rack, or the wrong amount of power, etc... anything can happen really. That said, I was at the dealership 3 weeks ago test driving a DII. The dealer actually said 45 degrees, and that he had taken one off-road to 38 degrees while in training. http://landrover.mrbaileyshistory.net | ||

There was a study done some time back by an independant company on tip-over angles. LR does some sort of a static test to get the 45 degree tip over angle (vehicle not moving). The independent company came up with a 42 degree tip over angle for the D1 with the vehicle moving. I think one of the Jeeps (Cherokee?) came in at 45 degrees. I wish that I could remember the source of the article. It was pretty interesting. Thanks, Mike B. | ||

assume 35 it will flip, take into considerations bumps and things and be cautions. rd | ||

I use the ass o'meter method. When my ass is so tight it is holding on to the seat, I'm at 30-33 degrees. I don't go any more than what the ass o'meter says. Never roled one yet. | ||

Bill! LOL, that one is GREAT...true, maybe you should consider the ass-cheeck method: when most of your body weight is on ONE ass cheek, then you know that your way too close... |
