Guy's I have a 2011 RGC with 8500 miles on it,I just bit the bullet and installed a 21" wheel and the two inch "drop in" lowering kit from progressive and went back with 20wt fork oil. I kept the stock 12" RGC shocks on the rear, Bike actually sets pretty level with stock rear wheel. Call me crazy but I rode the bike about 20 miles over some of the roughest roads I know of around here even hit a couple of 2" deep pot holes and tall speed bumps to try and determine if I'm going to have fender clearance issues. Of course I didn't hit these at hwy speed but fast enough to rattle you teeth. So far so good, no witness marks on the fender. I've done all this and a lot more to the softail but I know nothing about the Road Glide yet....
Just curious who else has dropped the front 2" and what issues you've incurred, if any?
I used the same front setup on my 08, the only complaint I have is the rougher ride. It doesnt have the unnerving brake dive anymore though. I have never hit the front fender, I doubt it has enough travel. Keep in mind the kickstand angle will be different. Eventually I will upgrade to the -2 monotubes.
I have Arnot rear air ride, so I cant comment on the stock rear shocks.
