Rock Krawler weld on bumpstops

When I opened these out of the box I really wasn't surprised that there weren't any instructions associated with them since they are WELD ON. Nonetheless, I figured that I'd better snap a few pics in case someone was looking at these and wondered, "gee willickers, how do I mount those?"

Disclaimer - The welder was acting up when I did these so the welds aren't up to my standard but what the hell, it's a bumpstop and that's why we have grinders.

For the rear, it's pretty simple. Just cut off the mounts for the factory bumps and grind the area and weld them on. I didn't take pics for this b/c it's pretty easy to figure out.

For the front, it's a different story. Namely, the factory bump stop mount has a cap in it part way up to retain the factory foam bs so there's no way you can use it to mount the steel RK bs. The bs would be way too long.
Here's the cap inside the factory mount.


First, I cut off as much of the factory bump stop mount as I could. I used my plasma to make the cut.


Since the factory upper spring mount has a hole in the center, which isn't the same diameter as the RK bs, I cut some steel to make a retaining plate and welded the bs to it.


Now, it can be slid into position.






Then, weld it into position and add your choice of paint!

Can you please snap a few pics of the rear?

I know you said its trivial but I am having a hard time visualizing how mounting them in the position of the stock bump stops doesnt limit alot of travel?

Sorry and Thank you

Nice, I wonder why they didn't make the top plate round? Just for aesthetics..

We mounted them inside the spring on my buddy's Jeep(similar to a TJ's design), worked really nice and also acted as a coil retainer.

You cut as much body off these as you need to to install... as long as you have enough body left for it to thread in, you're good.

That is under flex, it was my initial "test shot" after installing them. Essentially you measure your shock up-travel and make them that long, accounting for adjustments and if you plan to change your suspension at all. I ended up cutting a lot of the welded part off, and about 1/2" of the threaded part so that I could make them as short as needed.

Does it contact the pad ok with the extra inch the suspension adds?

I assume you are talking about the RK kit moving the rear axle back 1". In that case, yes, the bumpstop hits in about the middle of the front half of the pad.
