Yes, there is no flex in this thing at all. Not use to teeter tottering like the old days.
I will say once you kick in the factory rear locker, the truck just goes, and figures it out, with it's combination of traction wizardry. You here it moving power around or slowing wheel spin to individual wheels. It may hesitate for a second and then you will continue further up the obstacle.
I used the crawl control on one up hill section and set it for 5mph. All I had to was steer. It was interesting, but kinda boring, and took the fun and challenge out of it. But it did get you up the hill.
The rear axle is a Dana Advanatek 220. It's pretty close to the same axle they use in the new JL Rubicon. 8.66" ring gear (I think it's a 32 spline). Front is a Dana Advanatek 190 with a 7.48" ring gear.
The 10 speed is pretty crazy in 4lo, with a 4.69 1st gear and a 2.71 t-case low, you end up with a 47 to 1 out of the box. It's no Rubicon, but not bad.
Overall it was fun, but wheeling a 40k truck your still making payments on, with no body protection, a no flex and a long wheelbase has it's disadvantages.
I think I'd rather stick to point and shoot, who cares if I scratch it, it's paid for.
