Here is the summary I have to date. (BTW, I have the 9448s as I'm headed towards a 3-4" SFD - not put on yet. I'm pairing them with an ARB OME Heavy Duty Front setup-also not put on yet. I'll post when it's done. I re researched purchase options & LR Direct was still the best. I paid $85 on Fri 10/12 & got them in Eastside Seattle Mon 10/15.)
