Ok... time to break out the OBA!
I really like this, especially with my 400P-Auto that starts/stops as I inflate. It inflated relatively quickly, not much slower, if at all than the exhaust. I was also right next to it so I was able to continuously adjust it with ease. You'll also notice another reason why it was as good ideal to change the gauge on my VIAIR inflator!
After 3:00
The xjack started to really firm up and was lifting the body (extending the suspension). I decided to stop in 1:00 intervals to keep an eye on the pressure since you're not supposed to exceed 10psi in the jack.
After 4:00
Tires weren't off the ground yet, but close. The jack really was taking the form of the jeep. On a side note (no pun intended), this is a place where the S.A. sliders would really help out! You'll see why in the pics
