5.0 Great Cage- be prepared to trim for install

Great cage especially for the price. Very comparable to the Rock Hard 4x4 cage with very similar build quality and steel thickness. I am very happy with this cage. For install, a lot of trimming will need to be done on door surrounds (for soft top) and on freedom panels for hardtop for fitment. I also had to trim of the factory molding off of passenger side to fit a pillars but all in all, not a bad install.

4.0 Great for the price but far from just a bolt on

Tubing is high quality DOM and not junk HREW. Welds are solid but could look more visually appealing. Coming powdercoated is a bonus. Don’t expect it to fit perfect right out of the box. Jeeps tubs all have there little tweaks especially if they have been off-road prior. You’ll need to strap and pull bars into place etc. There’s quite a bit of trimming of plastics involved and you’ll have to cut the soft top roll bar surrounds quite a bit to clear the cage turn buckles. You’ll also have to cut the freedom panels of your hardtop to clear those buckles as well. The top must sit down flat onto the oem roll bar and the upper windshield crossbar turn buckles prevent that is why the freedom panels will require being notched out.

5.0 Awesome Setup

4.0 Surprised on the quality.

The cage is actually high quality. Tubing is all 120 wall DOM. All the welds look great. The install was easy because the parts were welded and assembled very precisely. All the threads were chased and pre greased. The hardware was grade 10.9. I was actually surprised on the quality. The kit comes with nice padding. This is a legit cage kit.

3.0 Great End Result

End result is great. Getting there is difficult. Took almost 6 hours to install and I'm a pretty handy guy. The drill hole template didn't quite match the pillar plates. The Passenger Pillar plate had to be modified to fit close enough to the fire wall to allow the holes to align. Took a lot of strapping and twisting to get everything in alignment. The rear cage padding did not fit correctly, but Smittybilt quickly shipped replacement and it was great to work with their customer service.

4.0 Nice solid cage, modifications required.

I bought this cage despite several reviews claiming the difficulty of installing. I liked the idea that this one had the best of both worlds from the top two Bolt in cage manufacturers. I didn’t like the knuckles in view of one and the fact that the other does not tie into the windshield. It took a full weekend by myself to get this installed properly. I would like to see the person who can install this in 2-3 hours as stated. It can take that long just to get it prepped. I also made the mistake of not reading the horrendous instructions all the way through first. I stopped at the first page once I realized they were pretty much worthless. No designation of which bolts in the bag go where, it was not that difficult to eventually figure out, but it took laying it all out and counting holes to figure it out. The left side did require grinding down by the top bolt to get it installed. Others just bent the flange on the Jeep. I didn’t want to do that to risk weakening the small flange that supports the entire cage. Once the cage was completely installed, i went to break down the boxes only to find what looked like a filler box (no weight to it and no writing on the box like all the others) only to find the padding. Now the padding the way it is cut requires it to be put on BEFORE you install the cage. I had to disassemble the cage and reinstall it. Now once completed came trimming the moulding corners. Fun! After completing this it was on to the soft top installation. I gave up and have decided to sell my soft top due to the amount of trimming required to get this to work. I don’t feel that the Door surround will have much support if i cut that much. I have talked to friends with the other cages and they had to do the exact same thing. I just decided it was not worth it. Overall, I like the cage a lot and think it will help out in a roll over much better than without one. For the price this is an outstanding deal when you consider you are getting the cage, powder coating and pads for just a little less than the others are selling he raw steel cage. Yes, welds look like they were completed by amateurs but I checked everyone and they look solid, just not very pretty. Probably as good as i could have done if i built the cage myself. I had no other fitment issues outside of passenger side door rail. Everything went together nice and easy after that. If you don’t mind hacking up your door surrounds for a soft top than go for it. As for the hard top, i wont know if it fits or any mods needed until the end of summer when i put the top back on it. I can say that it looks like it will go on easy with no mods as it actually pushes the sound bar down in the center, thus taking up less space. I see zero issue of anything that could get in the way of the freedom tops not aligning or needing trimming.
