R&D New Tacoma specific front bump stops

We need the video!

 

I don't want this to happen

 

LOL, Yeah @DukesTaco and other customers of mine would say otherwise.

 

LOL, NOSIR!! Neither one of us want that to happen...

looks like you have some fun!! Lots of skinny pedal is required to split those Super-bumps. They sure do take a pounding before ending up like that!

I'm assuming that was your front bump??

 

Another member suggested that I bring this up. Has this happened to anyone else & should I be concerned about them failing?

At first I though maybe a rock happened to get pinched in between but the chip is in the same location on both sides. Seems like they are getting pinched on the mounting bolts?

Have only had them on for a couple of months & notice this last week.

 

Huh...I'll have to go out and look at mine but yeah it looks like maybe that spot is making contact with the mounting bolts when it compresses.

 

Thanks. Judging by the material they're made from I think they might be ok but I'm concern if that damage will cause them to split eventually.

 

Cant speak for the company or OP, but if it was the bolt that caused it to chunk out there, it shouldn't chunk out anywhere else.... And I dont think that would make the rubber substantially weaker IMO

 

Depends on the material, once punctured, under strain or compression, it can cause the material the further split easily. This material doesn't seem like it would do that but just want be sure as I'm not a rubber/plastics expert

 

I had this problem when I blew out the OEM bump stops on the front of the LCA hauling ass across the desert. The front OEM bumps can only handle so much abuse. Your bump stop in the rear was over compressed by the FRONT OEM bump stop not being sufficient to stop the up travel. This is a known problem and specifically why these bump stops are for trail use and slower speeds. The OEM bump stop, that remains at the front of the LCA cant handle heavy hits caused from higher speeds or jumping. Looks like you had an impact that compressed the snot out of the front OEM bump stop and the rear bump stop was over compressed... I do know of a few of my customers that have used a button head bolt to fasten the bump stop which provides a few more MM of clearance and allows for Compression/Abuse than intended.

In the future I plan on creating a bump stop for the front of the LCA that will replace the OEM. You would be a fantastic Beta Tester for that!

I don't believe you will have a failure because of the chunk, but if you do I'm here for you. Keep me in the loop.

These bump stops are kind of a double edge sword in some ways. They provide a nice progressive feel that really helps keep the truck planted and stable at higher speeds and in turn we drive faster and its easy to over compress the front OEM bump stop.

I happen to be in the rubber and plastic industry... Its my day job. I'm a Toyota enthusiast and just applying my industry know-how to fill a void.

 

I see, ok thanks for confirming that they should be ok. I'll keep an eye on them & will try out some button heads.

Overcompress huh, yeah well that did happen recently. I cracked my shock buckets. All fixed now, gusseted & added top plates. Lesson learned & I'll try not to run my truck so hard anymore but sometimes it just happens.

You say for trail & slower speeds. Would it be better/safer if ran the stock ones since I tend drive my truck more in desert conditions? After I all I did blow out my shock buckets with these bumps on. Never had an issue before. Not saying that I blew my buckets out because of your bumps, of course my fault, just want to know which option would be safer in my case.

And yes, I would definitely love to be a beta tester should you come out with fronts for the LCAs. Thanks

(PS, just ordered a set of your rears, can't wait to try em out when they're ready. I'm running Wheeler's super Bumps in the rear now.)

 

For high speed stuff, you might want to look into hydraulic bumps like what the long travel guys run.

 

Or just go long travel.

I don't tend to run my truck fast & hard, it just happens sometimes. I have a good idea of what kind of abuse my truck can take, never broke anything in 14 yrs until last month.

 

That's a real good track record haha.

Knock on wood I haven't really "broken" anything other than a CV axle, but definitely have had to make some upgrades and speed up some maintenance on a bunch of crap. 4lo and slow can take it's toll over time, too

 

In comparison to running your OEM bump Stops in the desert There is a major performance improvement from installing my bump stops. You can do a small experiment yourself and see. Put your Stock OEM bump stops back on your truck and go run a stretch of desert. Then reinstall my bumps and run the same section of desert, With my bumps installed the truck is much more stable and able to handle the same section at higher speeds.

In the long run If your cracking Shock buckets you should keep your eyes on Gas/Air bump stops and frame stiffening. But in the mean time feel free to abuse the snot out of my rubber bump stops. I appreciate your honesty and if you do happen to split those guys shoot me a message and I will take care of you no problem.

You got a Utube channel or anywhere I can see some video of you railing across the desert??

 

Ok cool thanks, I'll keep running them. Oh yeah, I definitely felt a huge difference with your bumps on that's for sure. Just thought if it was safer with the stock bumps in terms of bottoming out. Again I'll try not to but shit happens. Plus my shock buckets are beefed up now so hopefully I won't have a problem anymore, not with that part anymore.

Sorry didn't mean to make it sound like I'm some sort of amateaur desert racer or something. No LT, just the common basic "mid travel" set up so I can't haul ass through desert terrain. No videos that I have. Just a video of me being stupid & jumping my truck 12 yrs ago. That was one time, never again, & was in the spur of the moment. Made for a good avatar though, beer was to blame.

 

@zero4 if I'm not mistaken, these bumps are also significantly cheaper than others, so if you have to replace, well at least it isn't breaking the bank

 

Yup those Timbrens are crazy expensive! I hear they don't even work all that well either.

 

Your profile pic says other wise lol
