Click here to check out the Slipstream installation video for a 2018 Jeep Wrangler Unlimited JLU!

The Slipstream has a vertical wall that sits behind the rear seats and supports two horizontal C channels. These C channels hold a removable lift panel that is held in place with quick release pins. They are only accessible from access through the tailgate.

There are side wing panels that fit tightly around the roll bar and follow the contour of the body for a perfect fit. This system was designed to be used with or without a top in place. Run it with the top on or off.  Access is through the tailgate and now can be accessed behind the seats.

Secure all your summer gear without having to worry about them being stolen.

The removable panel can be tilted up, removed and locked in a vertical position if you need to carry tall items. Secure anything you need like never before.

Additional slotted fence plates mount on top to incorporate stacking of equipment on top up to 150 pounds safely. The mounting brackets and C- channels allow for strong, secure mounting of the lift panel.


All of our Slipstream products do not come with the hard top bolts.  If you have a soft-top only, you can procure these bolts locally for just a few dollars.

Soft Top Users, be advised that if you intend to retract the soft top with the Slipstream installed, it will not lock in the retracted position. Its is best to Bungee cord the Soft Top to the tie-downs or other secure location.  The tie-downs may actually rub the soft top, so it is advised to not install them or protect the soft top from being damaged while in the retracted position...

Versatile, but lacking some quality.

Let me start off by saying I understand this is not a weatherproof product. I really like the security of the top, but the metal covering the sides is flimsy and warps when tightening down the hardware. Very time consuming install with tons of hardware. If you have the factory subwoofer, very difficult to tighten the bolts on that side. There are so many gaps, I really don't understand why. A 1/2 gap that spans the back of the seats, gaps around the roll cage, and about a 4" gap on both sides of the rear tailgate. Big enough you can see the contents inside. I like that the top flips up, but they really do not give you a way to secure the top once flipped up. The instructions are not very good since the JL is different and I was able to watch another customers video to aid with the installation. I plan to come up the gaps with weatherstripping which should have been included with the kit. Overall a decent product but nowhere near the quality expected for a $700 rear cover. I wish I would have just went with the the product I previous purchased for my JK that kept dust and water out, but lacked in a folding top.

Excellent Quality

The Slipstream install was fairly easy but does take 4 hours. I love the look and security it gives my Jeep and belongings. Excellent design. Looks great with my Bestop Trek top on my JLU.

Great Product/Tough Install

I finally got around to installing the Slipstream in my JLUR. This thing is really slick. Very solid and looks absolutely fantastic. The end product is better than I anticipated. The install was a bit of a challenge. It would be nice if each model had a dedicated video and directions that span the entirety of the install process from beginning to end. In the current form I needed to flip between multiple videos in order to complete the install.

Despite the issues with the install I would recommend this product to anyone who is looking for more security in their Wrangler. As these guys grow I'm sure their instructional materials will match the high level of their product and customer service. Thanks for providing us with this incredibly engineered product!

After in installing my Diabolical Inc. slipstream system in my JLU, I have to say I’m very pleased with how well it’s engineered and serves the purpose of securing my valuables when driving with the Soft top or Hard top.
Plus It looks great. Really like the access behind the rear seat.
Excellent customer support also.

Best mod yet for my Jeep!

Impressed!...To start of With I was impressed by the protection and packing of the product from the factory. Then again impressed by the detail instructions and quality of hardware included in the kit. The end result is the most impressive part! It is by far the best security product on the market today! The slipstream is so adaptable and transformable system I have ever seen, Love it!!!
