How steep of a hill can stock climb?

The video looks even steeper than a 45 degree angle. I have seen hills climbed that you would not think possible.
 
Second start? I don't know what that means.

I'm just saying, if 4Low and 1st gear gives him so much torque that he slips in the leaves and mud he was talking about, to back down and try again in a higher gear.

How would a higher gear prevent slip?

Second start = starting in 2nd gear and not 1st.

Higher gear = lower revs = less torque. The more torque you have, the more likely you are to break traction. So if he's in 1st and 4Low and ends up spinning his tires trying to get up the hill, he should go to a higher gear.

There's a sweet spot between "not enough torque to climb" and "too much torque causing wheel spin". If it's a very steep, very muddy hill, it's likely he might have to try and find that spot. I guess we'll find out when he gets back. :D

Yes but the point of being in a low gear is the power is far easier to modulate. I do agree with your statement, however.
 
Hollister Hills is a local OHV park that has a hill called Truck Hill. My visual estimation puts it anywhere from 45-50 degrees. We didn't have deep ruts on the last visit but the surface was pretty much all loose dirt. The 4Runner has the capability to tackle the hill as long as the driver uses the right technique. For this particular hill climb you need to maintain momentum throughout the climb. Once you've lost momentum its pretty much over with. Backing down a grade that steep on loose dirt is not fun. The 4Runner needs to be in 4Lo with the center diff locked and tranny in 1st gear. Keep the gas floored and just bounce off the rev limiter. If you back off on the gas, you'll lose momentum and its all over. Keep your eyes focused at the top of the hill and keep the nose centered.

Pictures and video really don't do this hill justice. You'd have to be there in person, and most notably in the driver's seat to realize how steep it is.

Here's a video of Blair taking on Truck Hill

depends on your tires and how sticky or aired down they are, as well as your suspension setup. something tells me if you had electronically controllable coils you could take a much steeper hill than anything with a fixed height.
 
In 4L the 4r will up shift pretty quickly (very low speeds) to 2 and even 3 - not as good as being able to select gear but works ok. I usually go with 2 so I can go up a gear to reduce torque or down to 1 if need more torque or need to lower speed to navigate. Always lock the center diff so you have full control. My opinion is that you never want to use D when navigating slick of difficult terrain.
 
Went down the hill easily... followed trail turn around part and almost got stuck in some mud/water rut which really suprised me, because it was something i feel a mini-van could get through (With some speed of course). Got back to the hill and stopped at bottom, regular drive and everything kept rpm at 2k and inched up, got halfway before the beeps and twitches started yelling at me so i put it in neutral and went down slowly.. switched it to 4lo (first time ever using 4lo) got up incredibly easily... I was amazed.. no beeps or twitches or anything! Me and my friend just looked at eachother an said wow!
 
Did either of those jeeps have lockers? If not, that hill should be no problem for a Gen4 4Runner.

Have any pics of the hill you're talking about?

nope both jeeps have open diffs. but its not the steepness that im scared of, on the right side of the hill there is a ditch that goes the length of the hill from top to bottom where muddy water flows down when it rains really hard. in that ditch are a bunch of big rocks. My 4runner is a bit wider than those jeeps. but i do have stock clearance (which shouldnt be a problem if i stay where i am supposed to be) and unfortunately the Dunlops. If i slide a little bit to the right i can end up in the ditch and risk rolling back down the hill. Next time i go back there i will get a picture. I do have a feeling i will try it one of these days though.
 
It's always better to be safe than sorry in my book! If you're uncomfortable with the situation, it might be for good reason. Just be careful and use your better judgement.

:bravo: Next time, take some pics.
