I have not heard of them, but the parts look sweet. The cooling head looks great. The price for the total "skeleton" looks right.
The only heart-ache I have is the fact that they used 6061 vice 7076 aluminum, but that is a small issue and it has more to do with strength.
I would caution on using aluminum skid plates, a-arms, and bumper brackets.
A bit on skid plates. Stick with the stock plastic or upgrade straight to Titanium. Do not stop in the middle with aluminum. You will spend far too much time reshaping them, and in the process end up destroying the structural integrity of the skid plate (metal fatigue from too many bend/rebends). The plastic is resilient and the Titanium is near indestructable.
A-arms. Same philosophy with one exception. These may not get bent as often, but when they do...you will most likely not be able to reshape them. Then you will have to lay out some serious coin to replace them. I run aluminum uppers and plastic lowers. The lower ones are more likely to come into contact with ground objects and are thus more likely to take serious damage. I have replaced a couple of lowers and no uppers since running like this.
The bumper brackets. If you make the entire spine of the truck metal (bulkheads, chassis braces, chassis plate, and bumper brackets), there is no where for the shock of head on impacts to be absorbed. One or two things will occur...you will shear the heads off screws in many places or you might bend the truck. Plastic bumper brackets are cheap to replace and absorb a great deal of punishment (as they were designed to do).
So when you upgrade...give some thought to what style of driving you might have (racer vice basher). Then give some thought to what you really want to make metal.
Hope this helped.
