School me on bump stops

[Krab]

You don't need a bump stop kit just to drive your truck off-road.

Guys with the 2014 have a bit stronger frame in that area as well.

Yeah, but I'd rather have the peace of mind in case I hit some terrain that fully compresses the suspension. Looks like I have another mod to add to the list.. Not that I'm complaining!

The other thing I've noticed with the better national HD springs, is that for towing I really don't use the bumps all that much.

With my +3 deavers I've yet to hit the bump stop on daily driving. Haven't had them off road yet

Not going to mention names but a vendor (they don't sell bump stops) told me that the RPG one will end up bending the frame inward as in twisting it over time. I've never heard of that and don't understand how just the RPG one would do that. Take it when it comes to bump stops there is no truth in that?

I am planning on getting a set of bed stabilizers as I have noticed that my bed is flexing and popping my bed cover.

Yikes. Not sure it's such a good idea to post something like this without any factual basis or at least posting who said it so they can own up to it and explain why they believe so.

Take a look at the design of the RPG/SVC vs the Icon.

The comment was made due to the rotational force applied to the frame by the impact of the axle into the strike plate. This is because the bump stop is mounted to the side of the frame.

In the RPG and SVC kits this force is converted into a compression+flex on the cross bar that runs between the bump brackets on the frame rails.

In the Icon mount there is a second link from the bottom of the bump stop mount on the inside of the frame rail to the cross bar, this distributes the rotational force created by the impact into both compression of the top link and tension on the bottom link preventing the bottom edge of the frame being twisted towards the side that the bump stop is mounted on. Theoretically this should make the mounts stronger and less likely to twist the frame clockwise on DR side and counter clockwise on PA side.

This post is no way meant to be flammatory of any product provided by any vendor its only purpose is to help answer the question raised in this thread. I have not seen any proof of the claims that have been made about twisting but would believe it to be true based on the mechanics involved in these systems if enough force was applied.

If you hit a bump with enough force to cause inward bending of your frame, I would imagine you have a lot more problems to worry about than just a bent frame at that point.

^+1...

Also, I'd imagine there are enough rpg and svc kits out there to confirm or deny that theory.

I would tend to agree with you, especially in the case of a single large hit. I could see it possible for repeated lighter hits to cause the frame to twist millionth of a degree each time and with enough hits serious damage to be caused over time. Again I have no proof of this happening this is entirely theoretical.

I could see that. But with how many kits are out there and how well they have held up, I don't know if it's enough of a potential problem to cause too much concern. We have to remember, the bump stop kit is there to protect us from ourselves when we see that jump and instead of slowing down we get that big shit-eating grin on our face and hammer down. Or in the event you're carrying a little too much speed it helps prevent damage. The guys that are running hard enough to cause inward bending are aware of the design limitations and have done other things to help strengthen the rear frame or just gone ahead and linked the entire rear.

I agree with you though. I could see the possibility of it happening and theoretically I definitely think it could happen. I just don't know if that possibility is real enough to warrant too much concern. Maybe it is and maybe we just haven't heard about any cases of it happening?

So who from ICON said this because I find this statement quite interesting.
