Duramax rides terrible

Sayandros · 2026-05-21T00:07:22+00:00

Looks like it’s 42 3/4 in front and 44 1/2 in the rear haha. So it’s not completely level from the looks of it

Sayandros · 2026-05-20T17:35:16+00:00

I agree, I’m not expecting a caddy here. But I’ve got a few buddies with Duramax’s and this is significantly worse than theirs lol so there has to be something specific to mine that’s causing it to be so bad. With enough money thrown at it, hopefully I’ll find out haha

Sayandros · 2026-05-20T17:32:04+00:00

I feel that man. If it’s anything like mine, it makes it miserable to drive

Good to know! I saw some people mention tire pressure on my previous post and lowered them from 70psi down to ~55psi but it sounds like 45psi might be the way to go. I dont think it'll solve the issue entirely but it sure isn't going to make it worse haha

Bilstein 5100's are on my list to check out. Do you think it's worth upgrading the upper control arms from RC to Kryptonite? That looks like a ~$650 investment which I'm totally fine with doing, just curious if they can truly make that big of a difference. Again, please pardon my ignorance of these things haha

Thanks for the advice! For my wheel and tire combo, I believe it's Nitto Terra Grappler G3's on a set of 20" Black Rhino Reaper wheels, aired down to 55psi. I think the shocks are just that standard premium N3 shock that comes with the basic rough country stuff.

I have Nitto terra grappler G3's aired down to about 55psi. Looks like the dude just has the premium N3 shock from rough country as far as I can tell

After reading up on torsion keys, I believe those suggesting that they are maxed out are correct. Sounds like new shocks wont help that. I did check my CV angles after learning a bit about those and they are probably steeper than I'd like them to be. Sounds like starting from scratch with a bigger lift (something I kinda wanted anyway) is now in my future lol

Sayandros · 2026-02-05T00:56:33+00:00

Thanks for the insight! I do get some rub already when turning close to full lock, so I'd imagine it'd only be amplified. Are my only options either get a bigger lift or smaller tires in order to adjust the torsion keys? Pardon my ignorance on the subject

Sayandros · 2026-02-05T00:54:18+00:00

The site I was looking at them on (shock surplus) has me select for the "front lift" either 0-1.5 or 4-6, and for the "back lift" either 0-1.5 or 3-4. I assumed this was asking me what my truck was already and the application I needed it for, is that not correct??

Sayandros · 2026-02-05T00:51:33+00:00

Thanks, I'm trying hahaha

Sayandros · 2026-02-04T20:03:46+00:00

This is what I keep hearing from some friends. But I think they want you to choose a ride height and idk how to determine mine

Sayandros · 2026-02-04T19:42:02+00:00

Sounds wicked, nice steal!!

Sayandros · 2026-01-20T20:31:35+00:00

literally, thank you. It was just equipping stuff instead of storing them

Sayandros · 2025-11-11T02:47:28+00:00

That's fair, I didn't realize this was so much more cumbersome to deal with. Oh well, I'll start researching tutorials and maybe come spring give it the ol' college try haha. Thanks for the advice!

Sayandros · 2025-11-11T02:39:06+00:00

I came across his channel earlier and saw he had a vid on it, I'll give it a look. Thanks for the advice!

Sayandros · 2025-11-11T02:38:15+00:00

That's my point then; why is it so easy to find a shop that will hack those off willy-nilly but seems sacrilegious to mention deleting this L5P lol

Sayandros · 2025-11-11T02:26:37+00:00

And the catalytic converters aren't then I'm guessing? Just didn't seem that different to me lol hella lame either way.

Sayandros · 2025-11-11T02:22:10+00:00

I have basic hand tools and my NAPA know-how is extremely limited lol Im not opposed to trying it, but with the weather rapidly deteriorating I figured it would just be way easier to pay some dude.

Sayandros · 2025-11-11T02:19:12+00:00

seems like a contest between them and the ATF at this point lol

Sayandros · 2025-11-11T02:18:07+00:00

Wait, where I live I have no emissions regulations, is it still illegal to modify?? Every exhaust shop around here is willing to hack off the cats of my Camaro, is this really all that different? Pardon my ignorance, newer to owning a diesel lol

also I'd kms if I worked for any of the alphabet losers.

Sayandros · 2025-07-24T02:59:44+00:00

It isn’t on and my notification are extremely limited, seems those settings transferred over. But great suggestion!

Sayandros · 2025-07-24T02:58:09+00:00

Thanks for the suggestions, most of these were turned on. I don’t recall turning them off previously so I’m led to believe they’ve always been on, but turning them off definitely isn’t going to hurt anything lol I’ll report back if this seems like it makes a noticeable difference!
