Differential drop opinions

[brownclown01]

You can remove the spacers and put your differential back to its stock height but you can't undo the grinding away of metal

I get that but it just a cooling fin so no big deal (I think)

There’s no cutting of any fins, the $30 differential drops don’t require any cutting, and yes you wanna do this because I’ve experienced bad vibration in the steering wheel from 40-70 miles an hour, seems very dangerous. (2015 Sierra slt,  3” lift)

What diff drop did you use? Other than the super lift and supreme suspensions ones they seem to need cutting

Not sure if you'll have to cut the fins off the front diff. Im thinking some diff drops are different than others. I say that because, I saw the Rough Country 3.5 inch lift comes with a diff drop and it says you need to cut the fins and notch the cross member. But the 3.5 superlift kit comes with a diff drop and they specifically advertise NO Cutting what so ever. So I would contact superlift and ask them about there diff drop.

 

But either way I would do the diff drop. Just my opinion.

The super lift is only a 1/2” drop the rc one is 1”
