I finally painted my Rock Rails to match my 100.
A few have po-po'd and commented they are not worthy. I have done my best to be up front on the construction and the limits they have. They should not be compared to a heavy duty slider with outriggers or steps. That has never been my intent. They do however fill an void for the recreational 100 owner well.
One thing that is commonly overlooked is the Rock Rails provide A minimum of 2" more clearance then other sliders. This is very important because once a slider or Rail comes in contact you have an unweighted tire with loss of traction. Once this occurs you ability to stay on line is greatly reduces and in some cases you will be denied forward travel.
The most common and first place you will see body contact (for most) is the pinch weld. I have seen this personal over the years on my own vehicles. As seen in the picture the frame rails and the Rock Rails are on the similar plane where as Slider will be hanging down 2". It is easy to see with the 100 series overall low profile guys with sliders see contact a lot and forward momentum and traction is reduced.
The Rock Rails will not protect you if you wedge your 100 between rocks, let you pivot off a rock, or let you come crashing down at speed on rock. But they protect in the most common place you will encounter as a recreational wheeler like a climbing or dropping off a ledge.
If your interest is running trails listed below your Rock Rails will serve you just fine just like they have done for me in the vehicle in the picture. The pictured 100 running 285/75-16 (sometimes smaller) has been on all of them along with many more and experienced no damage or required any assistance to complete the trail in 100 Style.
