Hey, I know a guy that has done the Diff drop
. For anyone else curious about it, I put a bilstein level on my 11 1500 set at 2.1". Afterword my cv angles were horrible. In 4x4 if I hit the gas you could feel a shimmy in the truck, If I floored it the front end literally felt like it was going to come out from under my truck. After changing C/V's and still having the issue I spent alot of time thinking it over and I determined that the issue was being caused by the C/V angle and that I needed to drop the diff.
I ended up getting in touch with zone offroad. I seen that they offered a " D48 kit" for almost $700 which is a 2.5" level kit with upper CA's and a diff drop kit. I only needed the diff drop kit though. So I got in touch with Kevin Bradshaw at Zone and asked him if they could sell me just the diff drop kit. He told me that unfortunately they could not BUT that what they could do is sell me a "portion" of the kit. He sold me for $165.04 the " D2300 Diff relocation kit ". This kit comes with some stuff you don't need such as leveling spacers. But what I did was resold the spacer and hardware for $100 on the forum if I recall and I basically got the diff drop portion of the kit that I needed for the remainder.
Installed the diff drop kit and have had zero issues since!.
