The wife and I will be having our first baby in early June and needless to say we will be starting to take some family wheeling trips. That along with many other reasons got me really thinking that it was about time for a roll cage in the JK. Also with the ever-growing need to always want to go bigger and do something sketchier it is nice to have the piece of mind that if things do go bad you and your passengers will potentially be as safe as possible.
I needed a functional roll cage that would be strong and do its job of protecting the passengers. I didn't care for many of the cage systems that were currently on the market as most of them are sport cages which are definitely better than nothing but not what I was looking for. Going to a custom shop was out of the question based on the amount they would charge for a functional roll cage that would keep the interior setup clean and flow with the jeep. I could build my own cage, which is a great option, but I do not currently have much time to work with or bending software and without software creating a clean and functional design would be much more difficult. If I went that route I would prefer to be able to take my time and fit everything perfectly which would take longer than I would like to spend especially since I don't have an indoor shop and it was the middle of winter.
All of those things along with some other features made me go with the new Poly Performance/Synergy Suspension Roll Cage System. They have a few different kits that you can choose from. I choose to go with all of them which consisted of their new A-pillars that go directly through the dash (instead of around it like their old design) while still retaining your HVAC vents. It also ties into the floor, and then ties into the frame. Front upper and lower windshield bars that run from side to side linking the two A-Pillars. Their two top roof bars which run front to back connecting the A and B cross pillars. Two grab handles. Brackets for new 4inch speakers. B Pillars that ties into the floor, and also into the frame. A harness bar which goes behind the two front seats and connects both the B-Pillars. Two more top roof bars to connect the B and C cross pillars. Finally the C Pillars which tie into the floor and have a harness bar which goes behind the rear seat and connects both the C-Pillars. All necessary hardware is also included in the kit.
Note: With this kit you will not be able to run your factory front speakers. You will need to a purchase a 4inch speaker and either use the brackets that Poly provides in the kit which mount to the A-Pillars behind the dash or re-mount them to your doors which Poly conveniently provides instruction for as well. Your factory tweeters you can use as well as your factory sound bar if you do not alter the roof's B-Pillar cross bar. You will need to do a bit of cutting, grinding, welding, prepping, painting, etc but it is all straight forward and nothing tricky as Poly/Synergy has taken most all of the hard work out of the equation already. I would say that if you have installed a suspension system and are able to lay a weld that will fully penetrate then you are well qualified to do this job. If you are having a shop do the install it shouldn't take much time for them, especially if you have your jeep torn down before you hand it to them.
Now onto the pics and the writeup:
I received 3 heavy boxes since I ordered their JK 2 & 4 Door Thru Dash Front Cage Kit, JK 4 Door B-Pillar Cage Tie In Kit, and the JK 4 Door Rear Cage Kit.
Each box was very well labeled and packaged. The hardware kits were wrapped in shredded cardboard which you will see in the below. Each kit did include a set of instructions also, but it is advised that you go to the Poly Performance website and print the most up to date instructions that are available.
Each part is clearly labeled, however be cautious when unboxing everything as the packaging tape will tear off the label. Most parts are easy to tell where they go, but it may be a good idea to keep the labels readable as its easy to switch sides on the pillars.
Every part is top quality with well made notches, beautiful welds, laser cut tabs to allow you to quickly and easily line things up while assembling.
It is an option to get Poly's Tube Clamps while you are choosing which kit you would like, however it only gives an option to purchase 2 for the front lower dash bar. I opted to get four total so that I could use them on the front lower dash bar along with the B-Pillar harness bar. After having these in for a bit I will say they are not necessary and I would have been okay without them. Although I do not at all regret getting them though as I know I may end up using them in the future. It does make painting a lot easier for the front lower dash bar since you can remove it to paint, then reinstall it, and I do like having the option to remove the harness bar if I ever need to for extra room or for any other reason that may come up in the future.
Here is an overview of all components from the three boxes laid out.
Now we start to disassemble the JK. First take off your soft or hard top along with your doors. I do not have a shop so the majority of my build will be outside under a hack frame I put together and draped tarps from for my white trash shop.
Then I pulled the front seats out. If you slide the seats all the way forward you can use an impact on the rear bolts, then slide it all the way back and you can access the front bolts with an impact.
In order to pull the seats out you do need to unbolt the seat belt strap. All of the seat belt bolts on the JK use a T50 Torx head socket, but be warned that Chrysler really secures these. You can use heat if needed. Below is how my bit looked after doing just the driver side.
Before you can fully remove the seat don't forget to unplug the seat belt sensor.
