Misc. Parts/Notes
-I would recommend not installing the rear bumpstops, my truck rides waaaayyy better then factory without them, bottoms out every so often but is not harsh.
-You need the carrier bearing shim if you have a 2 piece, I had a one piece so no issues.
-This tire size is perfect, doesn't rub at all.
-You do lose some turning radius with these spindles, but its still drivable.

Whats the lowest you can go in the rear with out doing a c notch?

 

4in roughly.

I have a 2/4 drop and still have enough space for the bump stops and won't bottom out. If I hauled alot of stuff or towed a trailer alot it would likely bottom out alot, but then I'd just install some helper bags.

 

How much does the c notch weaken the rear frame rails? I have a 2005 sierra rcsb and looking to lower it but not sure If I will leave it lowered forever
