The 3.0L Duramax weighs approximately 150 pounds more than the regular v8. You'll be fine with the eibach springs considering the spring compression rate is better than the stock ones and can withstand heavier than stock loads which is the main reason most people get them for.

It doesn't matter when you special order your truck. It takes about 3 months to receive your truck from the moment the dealership orders it to the moment it arrives to the train yard and is dropped off to the dealership. You will only qualify for the incentives/rebates that are available when you pick up your truck. As we've seen in the past, a strike, covid, and other things can affect production so timing it let's say 3 months before black Friday month would be a gamble because things can always happen that slow down or speed up the process. I used to place orders for customers when I used to sell Chevrolet vehicles up until a year ago and that's pretty much the wait time in a nutshell. My dealership was in California so it may shorter if you live closer to the manufacturing plant. Sent from my SM-N986U using Tapatalk

Well that makes me feel better about my situation. Was doing some research and looks like the Bilstein 5100 ride height adjustable struts and shocks would be compatible with these springs. Considering the Bilstein struts use the stock springs and stock assemblies there shouldn't be any fitment issues come time to replace the shocks and struts. So when you're looking at the parts list it's as follows: -Eibach springs -Bilstein 5100 RHA front struts (trail boss only) -Bilstein 5100 rear shocks (trail boss only) -Stock front strut assemblies I think that's a decent "Frankenstein" level that will also improve the spring rate.

Look into Navtool. They might make a module that you can hardwire and pretty much retrofit that into your factory system so you don't lose any factory functions. Sent from my SM-N950U using Tapatalk

Tomthetrex mentioned it on December 9. Idk how to quote an additional quote lol Sent from my SM-N950U using Tapatalk

Apparently, if you go back a few replies another member mentioned it. Might be worth to upgrade once it's out considering how easy the swap is. Sent from my SM-N950U using Tapatalk

It'll turn off regardless. I used to work at a Chevrolet dealership and sometimes we would leave the trucks running to play music on during events and they would turn off after 30 minutes of idling. There's no way to disable it unless you get a custom map for the computer. Sent from my SM-N950U using Tapatalk

I'm definitely going for some 35's once these are worn out. Thinking of doing some overlanding/adventure camping as well. Hopefully this kit proves itself this upcoming year. My last resort would be king coilovers and aftermarket upper control arms. So far I haven't hit trails that would require going fast on washboards which is where those kings would come in handy.

I have it set to the second from the top slot (maximum height). Thinking of hitting Hollister Hills again to try it out. There's a video on my channel (jefe z71) of the type of terrain it has. I bottomed out and scraped a lot the last time I was there. Sent from my SM-N950U using Tapatalk

Got around to installing the kit with the help of a buddy. It's a pretty straight forward swap. Noticed the ride doesn't feel like a boat anymore and it barely has any body roll on bumps or trails. It's a bit stiffer but that's because of the better spring rate compared to factory. The rear shocks were shorter than the stock Trail Boss shocks by about an inch and a half but I added some shock extenders from readylift to make up for the loss. At the front I got a little over an inch of lift which is more than enough to clear 35's. As is, 35's with a moderate tread pattern (not too aggressive) will fit with the stock suspension and the back sidewall of the tire will barely clear the upper control arm. You might have to remove mud flaps and trim a little off the fender liner. As far as needing new upper control arms with this kit I really don't see the need (personal opinion) as the ball joint is not over stressed and it's almost still at a straight angle. I feel that adding aftermarket UCA's will be overcompensating and it might stress the ball joint in the opposite direction since most UCA's are meant for 2 plus inches of lift. For the most part I'm pretty impressed with the setup especially since it's made for the non-trail boss models. If I would've known eibach was making a kit for the Trail Boss I would've waited. Nothing negative to report....yet. Sent from my SM-N950U using Tapatalk

Well that's just my luck. Every time I buy something the next better version comes out lol, just got a mavic mini and DJI decides to announce the mavic mini 2. Got a gopro hero 8 black...no worries, the hero 9 black is released within a month after getting mine. Eibach pro truck lift....shiet, some new ones are coming out for our trucks lol. Oh well, if I end up upgrading in the future I'll end up with coilovers. Sent from my SM-N950U using Tapatalk

I just got this kit delivered today. Aside from the stock struts/springs on the trail boss, was there anything else you didn't need to re-use for the install or add? Planning on putting these in once my spring compressor arrives. Sent from my SM-N950U using Tapatalk

A sales guy probably promised his customer the wheels that came on your truck and swapped them out in the back of the dealership thinking no one would notice. As the other guy mentioned, any GM dealer can give you a build sheet. Just give them your VIN and they can pull it from GM global which is like a little portal they have access to for all things GM. Some sales people can't close a deal to save their lives so they promise things they shouldn't and do shady things to fulfill those promises. Sent from my SM-N950U using Tapatalk

With a leveling kit or any other suspension modification it's not recommended to use auto mode (this includes bigger than factory tires too). You don't want the sensors to send false information to the system and next thing you know your whole drivetrain is trashed. Sent from my SM-N950U using Tapatalk
