No matter how much I read about how that is correct, I can't make my head wrap around it. To me that gives you maybe 2 inches of upward travel at the wheel.

I get it.  Now think about how far the wheel is from that bump stop.  Extend that out another 18 inches or so and you will realize that the travel up and down is quite a bit.  I shouldn't have called it a bump stop in reality, truthfully it's a barrier that reduces and helps the shocks when compressed.

Not really comparing, just offering a data point. My 3500 truck, with springs similar to the pictured ones, with air bags, tires at 60 PSI, rides VERY stiff.    More than others? Don't know.

Sorry, I've been AWOL for a while. 5 PSI is the minimum that's supposed to be kept in most bags to prevent the walls of the bags from being damaged, unless the bags have the stopper inside (which I be

The front torsion springs are different for different truck configurations based on the front axle load.  Do you have a plow package or camper springs?  What is the FGAWR on the door sticker?

My head has hit the roof... Supposed to keep about 5 PSI in the air bags, is that enough to matter, I wouldn't think so, but my truck is way rougher than any of my other trucks and rougher than any other 3/4 or 1 ton I've been in. I haven't been in a truck exactly like mine so I can't say its normal or not.

 

My head hitting the head liner is best indication I have that its not.

Sorry, I've been AWOL for a while. 5 PSI is the minimum that's supposed to be kept in most bags to prevent the walls of the bags from being damaged, unless the bags have the stopper inside (which I believe all of the Firestone bags do). Then they don't need any PSI when not under load (I believe, but could be wrong). However, I would still run a few PSI in them for the following reason.

The bags with the stopper inside WILL ride rougher than those without the stopper if the truck is bouncing enough to hit the stopper. Will it be rougher than stock? I don't know as I only buy Air Lifter bags without the stopper. But in stock form the truck has rubber stoppers already in the spot where the bags are installed. The stock stoppers have to be removed to add the bags. So, I would guess that at the very minimum, the bags with the stoppers should at least be equal to the stock ride, not worse.

As for hitting the liner, are you like 7 foot tall? I'm 6'2" and I have probably 6" or more above my head. Unless you are really bouncing that bad. In which case there is definitely something seriously wrong.

The 2018s must not have as much headroom. I'm not familiar with any differences that may exist between our models. I only know about my 2023. Even with the seat as high up as I can make it go there's still a few inches over my head. I don't recall ever hitting the liner, even when I've been off road.

So having a sun roof subtracts a few inches of headroom?

 

 

According to that same thread, it appears that the 2020+ has a little more headroom (less than 1/2"). But maybe the seat in the pre-2020 has a little bit more vertical adjustment?

I brought my truck to a local lift shop. Explained my feelings on ride being crappy, maybe running a leveling kit, and 35's. He told me if I never planned on doing more than 35s don't touch the suspension. Change the crappy Ranchos to Bilsteins, align the truck, and the heavier tire with a bigger front print will help hide our crappy roads. He also picked the tire. 295/65/20, Bilstein 5100s and a totally different riding truck. Finally got around to airing down the tires today to 50f 45r and this is a completely different truck. Side note my speedo was 1.5 to 2 mph slow with stock tires. In town it is now dead on! Sorry the ride is dirty! On hard right angled turns I thought I had some rubbing but it was only the wheel liner. I loosened it all up twisted it around and good to go!

I don't know, but probably some. 

 

I might be getting more used to my truck too - it doesn't seem as harsh at it used to. The Bilstein 5100s are almost a year old now, maybe they are breaking in - though I never noticed this on any of my other trucks...

 

Not sure if I posted this earlier either but I'm now at 60 PSI all way around unloaded.

      Clunk when putting truck into drive and reverse.

      By Matt Parker · Posted

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
