Wk2 Off Road Tips

This past weekend I went to my off road ranch. In fact, it was part of an off road 101 class. I was the only wk2 out there and all though I thought I represented the wk2 pretty decently it became apparent to me that I needed a little more knowledge on how to use my wk2. For example, I went up a steep hill and couldn't make it up the first two times. I literally had to floor it and made it up the the third time (see video). Later on in the day I tried the sport mode and it seemed to help. It then dawned on me what is sport mode for and should I turnoff traction control etc. It then got me thinking that i should start this thread to help guys like me to take full advantage of their wk2's. Those of you wk2 veterans please chime in.

By the way, one thing I noticed during the training is that the higher the lift and the better the tire the more capable the jeep is. I saw some folks get stuck in mud with stock good years and bald tires. Additionally, I noticed that a jeep or 2 struggled getting over some smaller humps as they didn't have a lift and their differentials got stuck in the dirt. I also learned that it would be good to carry a shovel, snatch block and an recovery strap.

FYI. I have a 2015 Wk2 Altitude with 4 hi only, 2.5" RRO lift, RRO winch mount, tow hooks and smittybilt winch.

Any advice for those of trying to take our Wk2's to limits? Btw, overall I was happy with the performance of my wk2 and most of the other wrangler owners were impressed as well.



Thanks in advance and look forward to the tips.

Re: Wk2 Off Road Tips

With your hill climb issues you found the limitations of the quadratrac 4 wheel drive system. Your jeep has open differentials front and back. This means that the power will take the path of least resistance. So if your back right tire and front left tires have poor traction...the open differentials will put the power to that right rear and front left tires and they wil spin. The quadratrac system will sense the wheel spin and apply the brakes to those wheels. This should force the differentials to send the power to the left rear and front right tires, which may have better traction. That's the theory at least...

The downfall to this system is that there is a time delay for the system to sense the wheel spin and apply the brakes properly. Obviously applying the brakes when attempting to climb a hill will cause you to lose momentum. The quadratrac system works well for daily driver jeeps that will see occasional snow or sand or mud. But it's not a good 4wheel drive system for off roading. The wheel spin and braking activities will always be laggy and fighting each other....shifting power from side to side as traction conditions change.

The quadradrive system uses limited slip differentials and is able to drive equal power to both wheels (front and back) no matter what the traction conditions are. Research or YouTube these systems to see the differences.

You can have the best tires in the world...but that system will continue to let you down in those climbing situations.

Re: Wk2 Off Road Tips

Hi,
Not quite sure why you couldnt climb in your first attempt...I'm no expert, but I'm thinking that you didnt shift manually with the paddles, and thats why your GC started changing gears and you ended up in a high gear with no power...
In those cases what I do is to shift manually, so I can keep my GC in 2nd. or 3rd. gear, always having power in my wheels, maybe that helps you in the future, it helps me.
Rgds.

Re: Wk2 Off Road Tips

I push the blimits of my qt1 equipped Altitude all the time, and its taken me everywhere my qdII hemi 2012 did. Driving style, knowledge, spotter and equipment are all keys to the offroad game.

when dealing with very steep or slick hills, you have to manage it. yes, trac control off. manually shifting, dont stop making forward progress. mine has sucessfully climbed very slick wet sedona slickrock without issue while ive watched other more capable rigs fail.

your qt1 will get it done, just dont be afraid of pushing it

Re: Wk2 Off Road Tips

Get out there and play and get some experience. There's no substitute. Sport mode is for fun on the pavement. (Engaging it automatically turns off traction control) Instead of the torque split from front to rear being 50/50, it's more like 80% rear, 20% front for a more sporty, 2wd feel for the twisties on the street. That could hurt you off road.
Momentum can be your friend if you scope out the terrain ahead of time. Just don't go charging up a blind hill only to find a huge rut you can't stop to avoid in time.
If you're having fun, you're doing it mostly right.

Re: Wk2 Off Road Tips

I would have carried more momentum trying to get up that hill as you did on the last run. Also, dropping tyre pressures a little can help with traction.

Re: Wk2 Off Road Tips

Guys, thanks so much. This is the advice I was looking for. Honestly, I forgot about the paddles to shift on my own. Alludc - good tip on traction control. I also saw your other post about airing down to 15-17 psi. I had 38lbs in my tires going up that hill!

Any thoughts on sway bars? Most of the wranglers disconnected them but quite frankly I found it to be a pain in the arse to remove and connect them when I put in my lift. Anyone seen quick disconnects for wk2?

For my next mod, should I do rock rails or skid plates first? Lastly, I got some Texas pin striping which thankfully look like they can be buffed out. Does anyone use or see any kind of body protection?

Re: Wk2 Off Road Tips

get some skid plates for sure, if you are goin to play and you dont at least have the trail rated mopar ones on there.

dont mess wit the sways (in my opinion), its not gonna be helpful to you with IFS/IRS. some do, but with such limited benefit, if any. we are NOT like Wranglers.

if you fear pinstriping, they make temporary clear stick on type vinyl that some people use.

and yea, eventually you may want rock rails...depends if you play as hard as me. Im constantly on mine

Yeah I plan on playing hard too. By the way after I saw your WK2 I got the mod bug. Additionally, it turns out my kids really like off-roading. I imagine in a few years I'll have about 3 jeeps in the family.

Re: Wk2 Off Road Tips

Being your first time up a hill like that, don't sweat it. When in doubt, walk it out. Get feel for how loose the ground is and any dips/bumps you'll hit that might cause you to lose momentum.

One thing with an incline like that, rock your steering wheel a left-right a bit; say 11 to 1. This will help keep the front tires on the sides of the ruts and hopefully some firmer ground so they don't get stuck in the loose dirt everyone else has dug up going up the hill. Also, if the ruts are deep it could keep you from bottoming out.

With soft ground and an incline like that you want momentum and to keep it going. You nailed it on your third try and that's what counts.

As for advice, I'll echo everyone else.

Traction control off - check
Skid plates - check. At bare, bare minimum get the gas tank plates. Last thing you want to do is puncture one while out.
Carry some basic supplies including small shovel, loppers, tow strap, etc.

For pin striping, buy some of the spray on wax and spend 15min or so wiping down the front and sides. A nice slick surface will help the brush slide off better. Obviously, if it's really thick you might want to think twice about taking the GC there ;-)

Otherwise, become friendly with a buffer

Even though you don't have 4L, you do still have paddle shifters and depending on where you go you can drop it down to 1st gear to get a low gear and more torque.

I'm still running the stock Michelins and so far have made it through everything, even on the spare tire. Tires don't mean squat if they're bald though.

Re: Wk2 Off Road Tips

I drove my MY11 QL Laredo over numerous soft dirt roads today. I did turn the traction control to the Snow mode. Didn't encountered any need for lifting the suspension. Other just get in more practice.
