Install was super easy. It does make it difficult to latch the pins on the bottom wall of the slipstream. I may just drill some new holes higher up on the wall to be able to latch them. Quality is A+ as with everything diabolical makes

I'd love to purchase, but need to make sure it will fit a Sahara 4xe.

The slide is a great addition to my Jeep,
The quality of the slide is great, and fits nicely

Holes were out of alignment on one side needed to be opened up a larger size or an oblique punch would be better possible the last hole only but for production its more realistic to do all of them but overall a great product

My wife and I I talked this in her Jeep. Early on we noticed the holes did not quite line up. We spent about 1/2 hr trying different ways of lining up the rack and inserting the bolts. Each ended with at least to being misaligned by about 2mm and not being able to fully seat them. If you can not get them totally screwed in, the rack does not work. I had to slot 4/6 holes with a dremmel in order to get the rack properly placed.
Once we were able to complete seat the bolts I stumbled across a problem of my own making. Screwing the bolts to tight warps the frame holding the sliders thus creating friction for the tray preventing smooth operation. As the tray was delivered with no instructions (not that you really need any) there is no warning of this or any torque specs to guide you. I would recommend loctite if you plan on going off-road as I stated above, if the bolts walk out, opening the tray could become an issue.
As far as the tray, workmanship and materials appear 1st class and I expect it to last a long time with proper maintenance. Pulling the tray out could become an issue as both sides must be released simultaneously and pulling the tray out with a heavy load on it can take some increased force.
I would still buy this again despite the price.
