Silverado 1500 LT Suspension

I'm out of my comfort zone as I've not worked on suspension since the late 70s.

I have a 2019 1500-LT dual cab, and a Flagstaff E19FBS.   (Silverado spec attached, PDF).

The tongue weigh of the trailer was measured at 629.4# (loaded)

When I put the trailer on the hitch, the truck squats enough to make people coming at me think I have the high beams on.  If I measure the physical drop of the hitch, from no trailer to trailer on it's 1.9".  Not a lot, but enough to piss off people coming at me.  The numbers, and the dealer say I'm not overloaded.

Any thoughts on my options to keep the back from sagging?  I'd like to head out on the highway in September.  Any thoughts welcomed.

Get a weight distributing hitch.  Otherwise your looking at leaf spring packs or airbags.

Thanks, Guys.  I'll look over the hitch.  Since it's basically where the Reese hitch is located, I'm trying to understand how it does a better job of distributing weight.

They work great if setup right.

I have one for my 25ft 6500 lb travel trailer. It's a must IMO.

What's the weight of your trailer ready to camp?

It looks like you are too heavy on the tongue compared to the weight of the trailer.

Is all your cargo up in front?

Go to a CAT scale at a truck stop and weigh it

Tongue weight measured at 629.4# with front sides storage filled.  Most stuff stored in back so when we get on site we can unload out the door.  One variable is fresh, grey, and black water.  That will change day to day, despite a theoretical equalization.

 

Another question, about braking.  The brake signal, (Blue wire, Pin 2), is this signal strictly an ON/OFF voltage, or does voltage vary with the amount of pressure placed on the brake pedal, hence the ability to set gain as part of setup?

 

BTW, thanks again for the suggestions.  From what I've read it seems like the towing will be safer and more professional than just the Reese hitch and ball, bare-bones configuration.

Very sure, Nestor.  See the doc in the link at the start of this thread.  2019 was the new body change year, if I recall the dealer's statement.

Some 2019's were build as 2019 LTDs which maintained the 2016-2018 architecture.

I'm pulling a 2021 287BHSS towed it with the 2018 and now the 2022 refresh and no issues with just a weight distribution hitch.

They are a must with the bigger campers but I simply stat they are a must.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
