Would it be possible or reasonable to have 2 layers on the front bumpstops? One layer would be stiffer than the other layer, so you get some damping, then a lot of damping. My thinking is that if its in 2 stages basically, it's a little more gentle. Does this make sense?
Also, totally interested in getting some if/when you decide to start making them. I have been needing some rear bump stops for quite some time. My gas tank skid is nearly sawed in half from my driveshaft and I'm tired of replacing the grease zerk on it.

Alright guys, I have some good news and a quick update.
The rear bump Stops are working very well. I have not had any rubbing issues on the fuel fill tube or inner fender well. They hold the weight of the truck without a problem while the truck is flexed out. I also have gone through some woops at about 30 - 35 mph to get the rear end to bottom out and it did well. not to stiff.
I was thinking about making the rear bump stops in a dual Durometer. So the last 1" or so of the bump stop would be a soft rubber with the remaining portion remaining the same firmness I have now. Ill attach a section cut (drawing) tomorrow showing what I'm talking about.
And for the front bump stops, I have these! What do you Think???

I think this is very encouraging and awesome to have this level of development happening within our community..well done, sir.
Might I ask, do you have a price in mind for these awesome products? I know everyone is ready to jump on in to support a forum member.

Holy hell man. Big internet high five for the design. Looks like just about a perfect angle to contact the body mount. Did you use some CAD on those or just roll the dice?

@ octanejunkie
said, it's really cool to see members kicking back some really amazing stuff. Thanks for taking the time to look into these. I'll be happy to try and break a set whenever you think they're ready for prime time.

@ Plastics guy
I am really liking those front bumpstops. They look like they completely solve the contact angle issue and are small enough that they won't interfere with removing the CV shaft. I remember reading in
@ Dirtco
s thread that he had to remove his timbrens to get the shaft out. How are their ride characteristics so far? i agree with
@ theesotericone
and would be more than happy to put a set through their paces.

They look awesome! But seem way to big. Looks like they would cause you to loose up travel. Some actually shave the stock bumps down to achieve more up travel.

I’m assuming they would be really soft like the Wheelers Superbumps are up front. I still bottom out mine on hard hits, but it takes much more to do so now in a very progressive manner.

No loss of up travel at all. They are soft rubber. They are intended to be compressed under the weight of the truck to simply give a little cushion before the factory bump stop makes contact and stops the up travel.
These will not prevent you from bottoming out your suspension on hard hits any more than the superbumps. You need a gas charged bump stops for a bottomless suspension feel. They were built for wheeling trails not prerunning.
Thanks for the reply guys, keep them coming. I'm getting closer to nailing these bump stops down.

Exactly. I do realize these are not made for pre-running, if they are anything like the superbumps (which clearly they are), they will really let you step up your higher speed performance. Obviously not to the extent of making it perform like a pre-runner but it helps take a step towards that direction of smooth, more controlled suspension cycle.
I'm looking forward to seeing these become available for purchase to compare side by side with the Superbumps. Got any pictures of how you attached the rubber to the mounting point? I'm assuming that you molded in a washer or something similar in there?

Wow.
This thread- and your work- makes my pants tight.
Take all my money too.
Hopefully black is an option for both durometers

Well said, you got it AssBurns, Here is a pic showing the design of the front and rear. Both front and rear bump stops have a large 1-1/2" washer cast in place. The washer will be completely embedded in the rubber casting.
I really do not think I will have any separation issues at all. But if I do run into any issues I will design around them or choose another raw material that works.
My approach is; The answer is never "no", But what will it take...

Thank You Tyler. Yes, Black would be the color of the bump stops. I'm only coloring my prototypes various colors to help me differentiate between the different prototypes I've made.
Here is a pic of one of my rear bump stop I cast in a dual durometer rubber colored black. The dark grey base could be made black as well. They are a little dirty from being tested but good enough.

Exactly.
And what will it take is usually: knowledge, time, money. Not always in that order though.
I think the angles of the fronts are perfect. The soft rubber is gonna give most of use exact;y what we are looking for. A cost effective alternative to hydraulic bumps. Will they be as soft as hydraulics? Never. Will they be close enough for the wheeling I do? Yep.

Looks like it should hold pretty well with that design. One concern I see could possibly be the bolt might be similar height as the stock bump stop causing metal on metal contact under full compression. I have had the allen bolt make contact a couple times on very hard hits. Granted, my driving style is probably a lot harder than the average 3rd gen owner, but it could still be a concern if it doesn't allow the stock bump to have any compression before contacting. I can measure the hardware height when I get home if you'd like on my Superbumps to compare with your's.
