I've put 2 of em on here at my shop, and they are an awesome kit, no cutting of the front diff and all the stuff they have available to go along with it you will want to make sure you get the new anti-sway bar and front driveline from Cognito also. Obviously takes more time to install this lift but it is well worth it.

I have alot of experience with those kits. You can fit 40's under it on a new body but you can not use a really wide wheel. On a wide wheel your turning clearance will be tight and can rub. Let me know of any other info you need on this kit.

With trimming it will clear. I have done it but it's tight. I would look at some 38's so you don't need to crank that much and then it will ride better.
