I am new to the forum and looking to level my 2007 Avalanche. I would

[Tackelbarry]

appreciate your opinions on the best quality leveling kit. Ride quality is most important for me. My truck was upgraded to 20” rims from the dealer when purchased new. Thanks for your help.

Most who want this do a front end lift.

Are you trying to level it by raising the front or lowering the rear?

 

[Tackelbarry]

Raise the front. I was thinking about just adding the 2” aluminum spacers on top of the coil overs. I was told this might stiffen the ride slightly but also reduce the body roll slightly. As a side note, my truck came from the dealer with 275/55/20 tires and rims.

You raise the truck Center of Gravity so it will roll more in turns.

Probably not stiffer or softer since same shocks and springs you are just effectively lowering where they mount with respect to CG.

Fo smoother ride find smaller diam wheels but keep tire OD.

You are essentially limiting the amount of wheel travel, particularly the down travel. But the good news is, those kits you mention are cheap enough and easy enough to install that if you don't like it, you can easily remove it.

I hope I'm not hijacking. I'm considering installing this rear lowering kit on my 2011. A 2" drop to level. I'd like to retain ride quality, though I'm considering upgrading the anti-sway bars too. Does anyone have experience lowering the rear of a 2011 or newer LTZ with Autoride?

Searching the site, when leveling most folks raise the front end. The few rear ends I've found lowered are the earlier models of the truck.
