The FRF Shock Shootout! All pre event details and discussion here

[Aaron]

Well said ICON! I think you guys bring up some great points.

Now we know, adding aftermarket bump-stops is only going to muddy the water, and I think especially so if they are used at different settings and PSI as was planned.

Thanks ICON! It sounds like we're on the same page.

Your position is that ICON shocks do not require bump stops. In fact your shocks are not specially tuned to take advantage of bump stops, should they happen to be there. Do I have that right?

If so, then all the loaner truck needs at a minimum is a gusset kit. If it should come with more that includes bump stops, we'll set the pressure of those stops to zero.

Hopefully CompanyNext is able to make the same recommendations; no need for stops, and not tuned to take advantage of them. If that's the case, we can run exactly like the ICONs will be run, saving time and resources. If CompanyNext says differently, we'll discuss and adjust accordingly when the time comes.

Thanks again!

I know it was mentioned before as far as frame brace or gusset kit and I know most of the bump stop kits that are out there you can remove the bump completely and leave the frame brace part in there. Unless you want to just take the pressure out and have it there to act like the factory bump? I'm assuming that's what your thinking on this right J?

 

[BigJ]

Right, pat. Based on ICON's feedback (the only player in town so far) I am more comfortable running with a bare minimum of a gusset kit. Should the donor truck come with more that includes bump stops, we'll air them down to zero and leave them installed.

This is going to involve working with the truck's owner, remember. Its going to be an easier thing to convince them to air down to zero their stops, leaving a nice contact patch there just in case, rather than remove it all together and let metal parts slap together.

Going back to the original post.....I am confused as to why the "bump stop" continues to be brought up? There are 3 shock manufacturers that produce shocks, none of which make a bump stop kit for the Ford Raptor.

If we are talking about bump stops, rear leafs, and so on that to me would be a suspension shoot out.....would that be correct? We are all for that but as stated we have nothing to bring to the table today but will in the coming months.


Edit - We do feel with the frame brace a factory bump stop should be present.

 

[Wilson]

the point is even playing field.

We aren't comparing bump stops. But they will be left installed for insurance. This is not a high budget test. If something were to mess up, the test could not pay for it. Therefore the test will include any insurance they see as needed.

Guys if the bumps are set at 0 psi, that means they are offering literally no resistance, other than friction. They will only come in to play, if a shock design fails to stop the upward travel of the axle. If the bump stops slam at 0 psi, the driver will feel it. He will be able to note it, and will be able to say that without the bump stop there, the truck could have been crippled. It's not going to aid the shock in compression until the very last second. IDK about y'all but I'm not worried that that is going to skew the results somehow. If it gets to that point, it's already obvious the shock under-performed there.

That's a great point that icon brings up and I know J has been saying it all along this is a shock shoot out! So we can all now agree that no bump will be used just a frame brace or gusset. Unless you feel even that is too much to level the playing feel? I know I I we're my truck I would at least want the frame brace to stay in. The bump can be aired down or removed but that's just me and I don't think my truck will be used seeing as I'm on the other side of the country haha.

Exactly what max said is in fact it contacts the bump then automatically we know we pushed the shocks as hard as we could to determine their breaking point. But let's hope it doesn't get that serious. We want them to be pushed but I think if in fact we do get a shock dyno then thus when we test the breaking point. Icon said it before and made a good point we should be able to test the shocks without pushing the limits of the truck to its breaking point.

My challenge for anybody worried the existence of bumpstops will skew result, offer your truck to test without them. Not only offer your truck to test, but know there is zero assurance your truck won't be damaged, when these shocks are tested, the suspension may bottom out at high speed. You must be ok with that and except that parts may be slammed together, metal on metal.

Honestly, i think many of you aren't getting it. A bump stop isn't going to skew results. They will only come in to play if a shock fails to keep the axle from traveling all the way up. At that point, it will be obvious at that point. Bump stops are just a fail safe, they are only there if the suspension doesn't work appropriately.
