Softer ride for a 2500.

[BB&Chiveon]

I put blistein 4600 on all around and made a huge difference 

[Epsilon Plus]

Look them up and get them from Summit Racing or somewhere "real". I had a new 5100 leak after like 3,000 miles that I got from an Amazon vendor. Bilstein was a PITA to deal with as far as warranty because they force you to go through the vendor. Well, you can imagine that Joe's Drop Ship Chop Shop or whoever is selling them on Amazon was a pain to get a hold of or deal with. Amazon even makes it very difficult to contact ghosty vendors. Summit would have processed the return immediately without trouble. It's not worth the buck saved.

 

Also, I drove around for a few weeks without a rear shock while I waited for the replacement. No difference. Potholes and speedbumps aren't going to compress my 3500lb payload leafs. Loaded with a trailer would have been different, but with sailboat fuel everyone hoping for any ride change is or those that say it's different are justifying their purchase. On 5100s with 37x12.5R18s at 40psi my wife can't even take a drink of water without wearing it riding in this truck on Arizona's perfect pavement.

 

You bought a big monster truck. It rides like ass. F'in way she goes boys (Trailer Park Boys Ray voice).

 

PS. For 20-23 owners looking for TPMS adjustment, I use the Pulsar LT with great results. Even GM still sends me diagnostic emails and my 45psi setting shows up "Green" and ok on their end

I post this frequently. I run my tire pressures at 55 psi front and rear and adjust as necessary at the outside temps change. I use an Autel TS508 to change the tire placard settings through the OBDII to 55 and 55. MyGMC app and Onstar email both show 55 psi front and rear.

 

My truck has the plow prep package and rides good with 750 to 1000 pounds of weight in the truck. 
 

Just got back from a trip to PA, 990 miles round trip. With the exception of the big potholes, it rides very nice for a 2500HD.

What year is your truck, pre 2024?

[rjgvt]

@revrnd Truck is the same one in my signature, 2024 GMC 2500HD AT4. I did the same thing to my cousin's 2024 Chevy 2500HD LT. The part number for the TPMS sensors are the same for his and my truck. GM PN 13542523. This can be read when checking the sensors for each wheel with the TS508.

Cognito soft ride leaf packs + air bags works

 

also I drop my air pressure to 50 psi when the wife’s with me.

@rjgvt I also have a 2024 3500, and have a TS508 but I can't seem to get to a screen on it that lets me adjust the TPMS placard values.

 

How do you do it?

[rjgvt]

@transam617 

 

Scan your TPMS sensors to find the part number.

Go to the Advanced screen and find your vehicle that has the same part number for the TPMS sensors. If you have the right one, there will be an option 5 that lets you change the tire placard settings. Will need to connect the Autel to the OBDII port. You can read or change the settings. 
 

For my truck I had to choose a 2023 truck as that’s when my truck was built even though it’s a 2024. 
 

Make sure to update the Autel periodically. Mine has free updates. I hook it up to my laptop with the USB cable and use an Autel desktop app.
