You installed frame stiffeners yet? IMHO, that should be the very first "mod" any Xj owner does if they plan to build it. Extends the life of the unibody exponentially.
The way my sliders were installed it welded into the unibody at 4 places/side with reinforcement then welds into the cage at two points. Cage stitches into all the pillars and also with floor plates at the other points. I have braced the front along the Steering with plate, but still unsure of the weight and bulk of fully plating front to back.
Thinking of fully plating the front, and my bumper/gas skid system in the rear will take into account reinforcements.
Thinking something along these lines could work with some 1/8 or 3/16 plate to fit around my steering brace, rocksiders etc and add extra structure without going all in as I would without he cage system.
Also noticed the additional steering box brace, anyone have input on these?
Here’s is the 30qt drawer dometic cooler I’m running. I believe Engel makes a slightly larger one as well that runs a little more $. @overlandhistory has one on his XJ setup and it’s a sweet little thing.
