DeeZee Tailgate Damper is Ezee
I purchased the DeeZee Tailgate Assist Tailgate Damper for my new 2012 GMC Crewcab PU. This is my second one I've purchased. I put one on my 2007 GMC Crewcab and liked it so well that I had to have it on my new truck. It's easy to install and I know it will last for years because my first one still works on my old 2007 GMC PU. It's a have to have product.

Great product
I purchased this product from here for my Sierra 2012 reg cab. The product is a perfect fit and 100% functioning. The product has a very easy manual to follow with clear steps for installation. To install this you just need simple tools and 5 minutes maximum. I do recommend this product.

EZ truck gate
A very easy install. Read all directions first. Or you may strip the gate insert plug. Just like the instructions say. I didn't read first and almost did strip it. Glad I stopped and read the instructions.

Tailgate damper
This was an easy install. With your hands full this makes it real easy to let the tailgate down. Small issue you have to keep track of the cable when closing it can get in a bind with the tailgate. I will put one of these on my next truck.

DeeZee Tailgate Assist
Great product without a doubt and fantastic customer service from Autotrucktoys.com. Factory instructions could be better regarding the installation of the nutsert fitting. I found that having a second person to hold the Allen bolt and use a pair of pliers to hold the washer/fitting which is missing from the instructions you can then tighten the nut and secure fitting part of the nutsert into the hole in the tailgate. After figuring out the trick with the pliers on the washer and fitting it was a 15 minute job. Overall I am very pleased with the product.

Tailgate Assist Damper
Installation instructions and photos very clear. The damper strut however contacted the tailgate at the upper pivot point upon closing the tailgate. A call to DZ and the problem was solved. 2013 Rams have an additional dimple on the tailgate that causes this strut to ever so slightly contact the tailgate. DZ shipped to me overnight a kit for Ford pickups-the upper bracket fits closer to the bed and provides the necessary clearance needed for the strut. Quick and easy. Excellent service.
