I just got a Silverado a few days ago... questions.

[XRipx]

Let me start by saying I have searched around for answer, and I couldn't find exact answers to my questions. It's about lift, offset and wheel fitment. I know this has been beaten to death. Please bear with me.

 

What I have:

2008 Silverado 2500HD Work Truck 6.0, 6l90 extended cab short bed

 

What I want:

Level it out

Fit 33s

 

What I don't want:

Extra pressure on CVs

To replace my bearings every couple years

Rubbing

 

This is my first IFS 4x4. From what I understand (please correct if wrong):

 

Lifts create pressure on the CV, shortening life span. New control arms alleviate this.

Negative offset wears on your bearings.

 

My questions:

The wheels I want are -6mm, is this close enough to neutral to prevent bearing issues?

 

If I got a 2.5 leveling kit (looking at the one from SuspensionMaxx), are there aftermarket controls arms that are made for lifts this small?

 

With the above being said, will I clear without rubbing? Looking at 285 75R17 (approx 33 x 11)

 

Finally, I searched around for common issues with these trucks related to anything and everything before I purchased but please any common issues that you know of I'd like to hear about them.

 

Thank you

If you crank the bars up a hair you should be able to clear those tires. The issues with rubbing has to do with the offset of the wheel. With that little bit of lift and that wheel, you won’t have wheel bearing issues. I have an 8 inch lifted 2011 2500. Same specs as yours with 37 on 20x14 inch wheels -76mm offset. And my wheel bearings are still good and tight after 2 years. I’ve only broke 1 cv axle due to the wheel being turned all the way and the axle binding. The leveling kit should include new keys and shock extenders. I wouldn’t use the extenders, but instead purchase new shocks that are longer.

Thanks for your response. Do you ever offroad with it? Because I will be doing some offroading, nothing too crazy, but light to light/medium.

Yeah I have property I go to and it’s a lot of sugar sand. I tow a trailer through it to my camp. I don’t beat on it off-road. This is from when I broke my cv axle. It was my fault because of having the wheel turned and binding the U joint. Truck does great off-road. The 14 wides really help with the floatation over the sand.

2011 has a different suspension setup than his 08.. they are both torsion bar but the 11 has a completely different differential, mounts are all different and so are the shocks and suspension parts.

 

08 is the same as a 1999... the frames didn't change until the 2011 model year.  

 

If you put on aftermarket keys and overcrank the torsion bars you will break CV axles.  On the newer trucks you can get a bandaid which I have on my own 2017 which is spacers to drop the front diff down.  On a older one though you don't have that option with the brackets they use.  You can add spacers but they don't fix the angle the joints are going to be running at.  

 

You honestly are better off buying an actual 4" lift on the 2010 and older trucks.
