Air bumps

4544 lbs in front? That's how much the entire truck weighs, front and back. How are you getting all that weight to the front?

I'll look into wheel studs. That's a great idea. As far as bumps go. I may have to look into those LR jounce bumps. I hear those are somewhat harsh over other hydro bumps though.

 

6)King 2.5 secondary bypass with the last stage tuned as a bump zone.

There are no more angles, conversations or arguments to made from this statement period!

Simple fact is bumps are not needed with A) proper valving and B) a bypass setup properly.

 

According to Username the need for a secondary shock is not required. Some moderate valving and a jounce shock should do the trick. I actually am leaning more towards his statement then yours about the requirement for a bypass. There is a couple ways to skin a cat after all.

 

You do understand physics right?

If you take a 1000 lbs and toss it at something at 100 MPH it is a little more than a 1000 lbs at the time of impact.

So.....when you jump and hit the ground your weight is multiplied.

 

I thought of that after the fact. All the weight shifts to the exact spot of impact multiplied due to the inertia. Got it.

 

"harsh". Hmm. No sir. They are infinitely adjustable. If you turn out the screws they aren't harsh in any way. If you cram 500psi in them and crank the compression screw in, I'm sure they are harsh.

You don't need either one really, but secondary shocks of any kind (bumps or bypass) allow you to have a smooth street ride and take some stress off the main coilover. It has to do less work. Less work= less heat. In your situation, I thought jounce shocks would be a good fit. Of course, it will not be competitive with a well designed long travel system with a bypass, but it will get the job done. To really do it right costs about half a million bucks. How fast can you afford to go? lol

 

I would use the money on an engine cage, engine mount gussets, coil bucket gussets, and long travel (front and rear) before putting air bumps up front.

Your coil buckets are probably already bent. The stock LCA is not built to withstand repeatedly jumping the truck.

 

The coil buckets are fine. I just aligned this beast and I believe my UCA or LCA may be slightly tweaked on the drivers side though. Only reason I say that is because before I was not able to reach a 0 camber situation on my drivers side tire where now, I am at a -.1 on camber, which I'm perfectly okay with anyways.

 

All kinds of awesome info in here! Roberto, what did you decide to do for bumps?

 

Dave! I had no idea you ever even chimed in here! Looking through my more recent posts I stumbled into this one again. better late then never!

I ended up going with Fox 2.0x2 air bumps for the front, with synergy bump cans to mount them on. I should be receiving them in on Tuesday and I'm going to have Jerry mount them on up for me. I'll be adding a 1/4 thick plate on the LCA for proper strike padding made by Synergy as well. Jerry or myself will have to cut it on one end to make it work, but it offers a lot of strike surface. I picked all of it up from Poly Performance for about $400. I can't wait to get them on and really start tearing it up out there!

As for the rears I'll eventually get to mounting some air bumps as well, but in the meantime, the full size Silverado Polyfoam bumps will and have been sufficing. The rear end is much lighter then the front anyways.

 

If I was going LT (or plan to jump the truck) there is no doubt I would go this route first, I would also reinforce the frame in the front and fully box the rear.
