Ball joints (and shocks) shouldn't be allowed to be the bottom out limit; above and beyond their pay grade.

Extended BumpStops... (6 Viewers)

I have two Timbren bump stops mounted on my front lower control arms and have had zero issue over many years of bombing around. Can't tell you how many compression hits the spressoWAGON has had...but it all works. Now, remember, like many other rigs, my suspension is all custom (except for the front LCA). What works for me isn't necessarily the ticket for another rig with different UCAs, shocks, etc.
It all boils down to cycling a given suspension and fully knowing where the extended and compressed bottom out is and then working backwards to protect the ball joints and/or shocks. The Timbren bump stops are cheap. The best would be to have a true adjustable bump stop but the space limitation for our IFS system is a real limitation for hardware. I would love to have a much more progressive compression bump stop that didn't result in such an abrupt stop...ala OEM or Timbren as discussed here.
Yes, I'm also running Timbren frame mounted bump stops on the rear suspension to protect the shocks from compression hits. But, again, you need to cycle your system to fully know WHERE the compression limit is and then work backwards (via compression limiters...) to protect the shocks in this example.

Ok good deal. I have Carl's old truck that he set up himself so I should be good too. My setup has the Icons with CVDC, Nitro UCA, and I have 2 Timbrens on each LCA as well (4 Timbrens in total up front). I haven't had any issues with my ball joints. Thanks for the help.
Any reviews on these ?
@spressomon has said a number of times about the importance of studying the full range cycling of your suspension when you make modifications and I couldn't agree more. I have discovered a number of things doing this. UCA to shock contact, tire rubbing of shock remote, contact with shock remote hose, brake line binding, determining best length for sway bar links, etc. You may think because you spent big bucks on shocks from one vendor and UCAs from another it will just bolt in, well think again. Key words TWO vendors.
I have two Timbren bump stops up front. In back I have Airlift airbags at relatively low pressure. Not using them so much to increase spring rate (that is a side effect), but more as adjustable bump stops by varying the air pressure so I can tune them for load, road, and my lead foot.
How do you like the front bump stops? Is the spacer you ordered (for the front) in the following link?

Do you find that using the airlift bags in this way requires constant refilling to your desired pressure? My bags and lines exhibit no static leaks, but always lose pressure when used on the road.
I haven't found that to be the case. Did have an issue with the hose connection to the bag, it would leak when bag flexed. Once I clamped it, no issues.

Care to share which clamps? I strongly suspect I have a similar issue
That was a long time ago. I used tywraps with Permatex High Tack on the fitting for a while, but tywraps only last a year. Stumbled across some small clamps in an auto parts or a hardware store, no clue now where it was. The High Tack by itself might be enough, I use it on most hose fittings.Care to share which clamps?

Bingo, TYVM.
I'm liking the front bumpstops so far. I have the Wheeler front bump stopsHow do you like the front bump stops? Is the spacer you ordered (for the front) in the following link?

I got a set and put them on yesterday. On road has a stiffer, more responsive suspension feel but not rough. Off road has a smoother response on hard bumps and has taken most of the harshness away. So far I’m pleased with them. When I finally upgrade to a swing out style bumper and heavier springs I may move to putting on rears.
Just installed a set of 4 today. I have a set of Timbrens for the rear. So I will be running both brands.

I found a trick to ease installation. I took the hex head cap screws and wrapped some double-sided tape around the threads just below and touching the bottom of the head. That allowed me to screw the cap screw into the bump stop so it would hold tight. Then I was able to spin on the bump stop with the screw into the mounting hole and run up the threads to hand tighten. After that, it only took a few turns with the enclosed Allen wrench.
Regarding the wheelers front bumpstops: Did you happen to measure before & after up-travel? Any idea how much up travel is limited?
I don't have specific measurements. I can say the opening is very close at normal height with a 2" lift.
It would be interesting to take some chalk and rub it on the LCA contact points to see how far the mount touches.
Oh.. I just found this thread. My results are on par with the information provided in this thread. I have nothing new to report other than I like it.

Wheeler Offroad "Superbumps" installed.
So after reading on a few forums about Wheelers Offroad bump stops I found that the part number that fits the FJ Cruiser is also compatible with the LC100/LX470 chassis. Over the LCA there are two positions where you will find the OEM bump stops. You could mount the Wheelers "Superbumps" in all...

Sorry didnt get a chance to clean all the mud from my last outing.
But here are the Timbrens installed in the rear:
compared to OEM lol:
Looks awesome -been trying to follow this thread and the links to the product - can you share the link? Thx
