I'm thinking about adding some rocker panel protection to my CJ, and wondering what people reccomend. I really like the looks of the Sun Performance rocker guards, but am not sure how durable they are. Has anyone used them, and are they up to the task? Or should I go with the rock-slider type of protection that attaches to the frame?

Neither. For $20 you can make bombproof protection using 1/4" thick angle iron. I used 4x4, just drilled thru the body and bolted it on using alloy buttonheads. You don't need to attach to the frame, the support of the body panel is plenty to support the vehicle, you can jack it up from there. I've landed pretty hard on rocks, no problem.

Hey, thanks for the tip! And the pictures, that looks great. It's held up pretty well too? Rocks, hi-lift, etc? I think you've convinced me to save my $$ on the fabicated stuff! Now how about an equally low dollar tip for replacing my engine... heh ;)

Any ideas for us fiberglass tub folks? I want to replace my nerf bars with some kind of rocker protection, but I don't think I could secure the angle iron to the tub with this method.

I have the Sun Performance product and am happy with them. Very strong; I've jacked on them, I've dropped the whole weight of the jeep on them and spun the jeep on boulders all without any damage. If I had it to do over I would copy what Brad did. As I look back, that was way too much money to spend on rocker guards. Especially since I'm gonna chop them up now and put TJ flares on.

Bob, what about using backing plates to sandwich the body between? Otherwise I guess you would have to go to the frame; There is a guy in my club that makes rock rails that weld to the frame and sit just under the rocker. I think he uses two by three rectangular tubing; just takes a piece long enough to cover the rocker and brings three legs of of it to the frame. They're low profile and strong.

Hmm, I think you just solved my problems. You said "backing plates" and my initial reaction was "nah, it would look dumb to have a few pieces of 1/4" steel plates on the inside to basically act as washers" then I thought of this- a whole strip of 1/4" steel on the INSIDE from the door sill to the floor and from the rollbar as far forward as I can get it. Then I have the F/G tub sandwiched between 2 plates of 1/4" steel. That should spread the load quite nicely, and may even help alot of I ever get T-boned. How does that sound??

Brad, what size bolts did you use to attach your rocker protection plates? I imagine you used some rather large washers on the other side, have you had any problems with the weight of the angle iron ovaling the holes for the bolts in the body? I'm just curious before I begin attacking the project. Thanks!

Mine are very similar to Brad's. They are 3/16" instead of 1/4" (lighter and still plenty strong) and extend from fender opening to fender opening (one piece). My Jeep's has rock rash already and I wasn't worried about messing up the fender lip. I did herculine the outside of the tub behind the angle iron for rust prevention though. My question is why the need for super strong fasteners? If you come down hard on a rock the bolt isn't taking the force from the blow. The bottom of the angle iron against the tub is. If something is pulling the angle iron sideways from the body, the sheet metal will tear and bend before even a grade 2 bolt will break. Seems like overkill to me, especially when a search for a certain kind of hardware is taken on. I used 5/16" x 1" black oxide button heads and don't know what grade they are.

Yeah, Bob that is exactly what I had in mind. Spread the force over as great an area as possible, and I would think the body wouldn't suffer on impact. I'm doing kinda the same thing with my rollcage, where it mounts to the body, only making the plates as dissimilar in size as I can; that way the shear force would be spread out as much as possible. Mind you this is temporary, until I can whip up some frame mounts.

See attachment for photo of my rockers. The idea of a strip of steel behind the tub is a good one. I thought about it but got tired of the project when I was doing it and havent gone back to finish the thought.

Snowtow:

What are you using for your step?

That is the biggest thing preventing me from doing this upgrade, my wife insists that I have steps to help her in.

Are yours similiar to H8monday's?

I think NH Northern sells the folding step, yep just found it. Black for 5.99 or Stainless for 19.99 part 127280-c158 and 127281-c158 (NorthernTool.com). As for rocker protection I was thinking about getting some "T" channel and mounting it upside down, so the top of the T makes a small step the whole length of the guard and will provide a little "stand off" space from the side of the body.

Snowtow & BMB Thanks for the info.

When I get the rollbar done and a couple other projects finished this spring, the rocker protection is going on.

Again, Thanks!
