I am in the market for some good rock sliders. I have seen essentially two types: those that bolt to the body and those that do NOT.

Here is my question - those that bolt to the body seem to be on the higher end, but I would think that if they are bolted to the body and take a good hit, it would result in body damage. What am I missing here?

Also, wouldn't they tend to hold moisture, dirt, etc against the body and promote rust?

Any and all help is greatly appreciated.

 

not sure about the body mounted ones.

i have the shrockworks sliders that bolt to the frame. Good Stuff..!
BUT, if you wanted to run a "long arm lift" you must use the body mounted sliders.... (from what little i know about it)

 

A good body mounted slider will distribute the bump throughout the slider and not allow body damage. When installing the body mounted sliders you usually have to apply sealant that acts as a buffer between the body and slider and to keep moisture out.

Not completely off topic, but you may want to consider these: Poison Spyder JK rocker overstock sale

 

Thanks for the info and the heads up on the sale.

 

I had some doubts at first but on our silver jk we have ran the Purejeep Rock Sliders and they have held up very well through a lot of abuse with minimal body damage.
I think the body mounted rock sliders are here to stay and are quite strong giving a lot of ground clearance
The ultimate would be running both a plate on the body and a frame mounted slider. This is kind of redundant but some customers want to be positive no body damage happens to their rig.

 

I bought the Poison Spyder rocker nockers. They bolt up using existing hole and new holes that are drilled. It is very solid and looks great.

 

this was a concerns for me as well, ohio road salt is terrible on jeeps.

My TJ has poison spyder rockers that mount the same was as the PJ's. I removed them this year to make sure the rockers were ok. To my suprise there was no rust anywhere. They have been on my TJ for 4 years.

I'm not worried at all with the PJ sliders on my JK. i have no doubt in the strength.

 

shrockworks sliders

 

I have the PJ sliders on my 2dr. I find that most of the time I will hit the frame rather than the sliders due to how high the sliders are. When I have hit the slider, I haven't received any body damage.
I was also a little concerned about the dirt/rust issue but where I live it's not really an issue. Also, the instructions say to use a sealant between the jeep sheet metal and the sliders to help prevent this. They were a PITA to install but I couldn't be happier with them.

 

I prefer the sliders that bolt to the tub!! I have no flares and my tires throw rocks on the lower part of the door jab. So, if I get a set that mounts to the body I do not have to worry about scratching the paint!! Just another option to think about if you are going with tube fenders down the line.....
