Who makes the best frame sliders?
Are weld-ons worth the extra install compared to bolt-ons? (For a non-serious off roader)
Can bolt-ons be used as Hi-Lift jack points at any given part of their structure?
*Mounting legs...For your model I would suggest 5 mounting legs. If the company your looking at is only providing 4 then I would steer clear. The more mounts the better.
*Length... The longer the better and the more load that's spread out the better. Some companies in here provide sliders with poor mounting options because IMO the mounts are way to far back from the end of the tube in the front.
They will claim it's because of the forward cab mount, but they just can't think outside the box. The engine is the heaviest part of your truck. If the front tube doesn't come to within 2" of the front fender I wouldn't want it. Also the mounting leg should be right up against the cab mount not 3" back from it.
*Material....Personally if you treat them as you say you will not need DOM. Most of the guys I know who have exo cages and beat their trucks do not run DOM. If you have the money go for it. If your on a budget steer clear.
* Design...personally I don't need a slider to be farther out then my wheels. I got sliders to keep the bottom of my cab in working order and for a recovery point not to kick my truck in a direction. If I drive into a rock thats my dumb ass fault. My sliders are mounted up to the bashed in pinch weld to gain clearance. The lower the slider the more you will hit it. Personally I think all should bash their pinch welds before mounting sliders and then mount them up as high as possible.
* Price.... some are much more money then others. I have even seen some "left over" sliders on sale in here for FAR much more then I paid for my hybrid weld on sliders. Personally anyone wanting more then $400 for a basic slider is crazy IMO.
* Finish....if your only mall crawling get powdercoat. Most will say it can not be touched up, but that's 100% false. Powder coat if a standard color can be touched up and blended in just like paint with paint. If you get them for actual sliding then spray paint them.
