Ran Upper Ajax Mine Trail on 9/23/23, I have an 01 XJ, 5 1/2 inch lift and 35 in tires, front and rear lockers, a 97 TJ, stretched (110-inch wheelbase), 350 cid eng, 40 in tires, basically a tubed out jeep/buggy, and our third jeep was an 89 YJ, 350 Cid Eng, also with a 110 inch wheel base with a double transfer case set-up, also basically a buggy on 40 in. tires. Based on the previous review, the trail has been eroded a lot by all the spring rains. The original description on this trail is now very much out of date as far as the obstacles, there are I believe now, 6 major obstacles, five being extreme for any jeep with even moderate upgrades.
It took us about 4 hours to complete the trail, I had to winch off three of the obstacles, of the three I drove through, two of which gave me some nice body damage. The other two jeeps with me also had some trouble on three of the obstacles but took a different line having 40-inch tires and an extra four inches of lift. It's my opinion the best set up would be a 110-inch wheelbase (preferred), and min 37-inch tires, 40 inch preferred and some real strong rock sliders. Taking a long wheelbase vehicle on this trail, in my opinion, would be a serious mistake. GOOD LUCK. Sorry with all the trouble we had, did not bother with pictures. A bit of video was taken, when I receive them, I'll try to add them to the review later.
