First time Lift and Wheels (Opinions and Advice)

This is my first time going about lifting a truck and I’m trying to learn as I go.
In short my issue is I’m stuck going back and forth between getting just a 4” lift or 5”(5.5”).
Now, being it is my first time I’m looking more for opinions and advice about which one works more for you and why (to ease myself).
As far as what Im wanting, id like to have a slightly aggressive stance, that doesn’t require me to have a rope ladder to get in, without degrading the power and comfort all too much.

Again this is my first time and Im not decided on anything yet. I would just appreciate any help, advice, or tread support given.
I drive a 2015 Z71

I just put in the 4" Rough Country lift and upgraded from 265/70/18 to 295/70/17s which is a true 33", also significantly wider. I couldn't be happier. I had to however reshape the wheel wells closest to the doors to accommodate how wide the tires are.

This is what she looks like now, (295/70/17)



And this was after the lift with the previous tires and rims. (265/70/18)



And other post lift images.

I think I say this to anyone that has or will ever ask about lifting their vehicle.....If you have the choice between 4 or 5.5 go with the bigger one.....everyone thinks that just a little is enough, but if you got the itch to lift it now you will get the itch again and be unhappy that you didnt go bigger the first time. You will be telling yourself i should have gotten the 5.5 instead of the 4inch.....

Now as far as ride goes, I didnt see much of a change. I went with the 6inch and honestly dont think there is a big enough difference to tell. I also dont think there will be a big enough difference between the small lift or the bigger one...So you might as well go with the bigger one. If ride quality is that big of a concern you shouldnt have gotten a truck.

Last thing ill talk about is power, I feel these truck are far from being fast to start with, I have the duramax, which i felt still has plenty of get up and go, with the bigger tires.

If i were you, I would just look around and find what looks the best to you. So think you can go to big, some think its not big enough....Wheels and tires will play a big part in the look of the truck as well...Take some time float around here and do some reading. Lots of good info and tons of pics.

I went with the 4” lift on 33x12.5/20’s
