Leveling Kit for original Grenadier full Drawer system

Outstanding quality. Very well packaged. Exceptional personal customer service!!!

The Diabolical Mid Deck for my Grenadier is very high quality and a perfect fit. Wonderful solution for additional storage! Diabolic is easy to work with

This product is well designed and easy to install. It took longer to unwrap the parts which were well protected for shipping than the install. Thanks to to Team at Diabolical for doing the work to put out such a great product.

Designed with precision, the Slipstream Security Enclosure integrates with factory parts, including covers, mounting points, and your existing floor mat. Though installation demands some effort, its straightforward and the design allows for quick and easy modifications and removal when needed. The enclosure also maximizes usable space while providing security when your bronco is topless.

The Diabolical Inc. Grenadier Mid Deck shelf is a great addition for convenient storage in the rear compartment. It is a perfect fit to the D ring factory mounts and a simple installation. It is professionally made and finished and will withstand the test of many outings and rough roads. The customer service is excellent and extremely quick to respond to any questions. I highly recommend Diabolical, Inc. and the Mid Deck shelf.

Super easy install. Takes about 10 mins from unboxing to complete installation . Did have a quick question and called Diabolical direct. Alan (owner) answered without having to leave a VM and wait on a call back and had me sorted out in no time. Glad to see high quality American made products still being produced by family run companies. Highly recommend them for this product or any of their other offerings.

This was exactly what I was looking for! Like all of the other Diabolical products, extremely well made.

I feel obligated to write this review due to the outstanding and excellent experience I had with Diabolical Inc. Alan is a prime example of incredible customer service. He took time out of his day to answer all my emails and even jumped on a FaceTime video chat to explain a few things to me and answer all questions I had. First, the packaging of these items were incredible. It took me longer to unpackaged the item than it did to install. That’s a good thing! I feel confident anything I order from Diabolical will arrive undamaged and on time as expected. Next, the items themselves are extremely high quality and work perfectly. I suspect these items will last the lifetime of the vehicle. They are a perfect fit and look great in my 2 door bronco. Very professional looking and the functionality is outstanding. Back to the customer service…now a days great customer service is a thing of the past. But, not at diabolical, Alan is extremely talented and kind. He answered all my questions with a smile regardless of how obvious my questions may have been. He answered all my emails and was very helpful during the ordering process, install, and after. The install was straightforward and easy. I took my time and it maybe took 15-20 mins. I can not recommend Alan, his company, and his products enough. They far exceed any competitors out there. I highly recommend this products and this company to everyone.

I purchased this product with an 8” extender (with sliding tray). The packaging was excellent, so everything arrived in perfect condition. Everything is cut to very tight tolerances, and everything fit they way it was intended. One person can install it, but I would recommend having a helper. I had a couple of questions before buying and during the install, and Alan made himself available to answer questions (even during the holidays; thanks Alan). I was so impressed by everything about these products, that I just ordered the sliding floor. Can’t wait to use it in my upcoming trip.

I have yet to install the slipstream (can't wait) I'm in the north east-cold no garage. Looking at videos and seeing testemonials this looks like a very good purchase by me
