Timbren vs Sumo Spring

[StormRnr]

I made a video with more info and thought and detail about bump stops than anyone should put into the topic. But in the process, I did a detailed comparison between Timbren Active Off-Road Bump Stops and Sumo Springs.

I did a compression test on Timbren, Sumo and Stock bump stops and the data from that is attached.

The Sumo Spring has more material, and compresses more and so it's noticeably softer.
But neither is really a bump stop, they're both overload springs. Both will limit travel and have a harsh stop and stiff ride. But the Sump is betterall around.

If you need a bump stop that limits up travel because of longer shocks or bigger tires, these may be a good option. They also might be a good option if you want to add some load-carrying capacity without upgrading anything else.

If you want an upgraded bump stop for overlanding or off-roading, I wouldn't recommend either Timbren or Sumo.

I just installed Sumo bump stops on my truck. I have a decked system loaded with work tools and the bottoming out was driving me crazy. I do 95% of my driving on paved roads so this worked great for my needs.

I have sumosprings and they definitely help, but there are times I wish they were adjustable.

I installed Sumos in the rear of my truck about 5 years back (it's one of my more popular yet terrible videos

) they aren't really holding up that well. I will need to replace them soon I expect. That said, I did abuse the hell out of them.

Hey Rev,

I was thinking of getting these (Blue) for my TRD Sport. Are yours coming apart? Thanks

Only the tops, I'll try to grab a picture today

I guess that's maybe not as bad as I thought

One of them definitely looks chunked up! And the blue ones are of lighter material. I don't plan on doing more than some glorified dirt roads and beaches, but I'm going to give them a shot. Thanks!

My vote on rear bumps is still the Archive Speed Bumps if you don't need to limit travel, but pretty much anything is an upgrade over stock. When paired with the Wheelers Superbumps up front you don't even feel the suspension when it bottoms out <3.
