Well, they (rockyroad dudes) were fast on the e-mail replies but I ordered on Feb 28th, and they were delivered March 21st. But they had none on hand and were waiting on a truck or something.
The extended bumpstops will hopefully keep the wider larger tires from rubbing the inside fender or outside cladding. Basically under flexing the larger tires would hit and rub on stuff and the extended bumpstops will stop them on up travel before the tires can hit and rub anything, hopefully. Zeus and others have done this and worked well.
Energy Suspension Part # 9.9104R (for red ones) - "Designed with a large reinforced metal plate welded to a mounting plate and molded-in. 4 1/2" tall,
2 1/2" wide. 2 per set" Evidently if you do this all you have to do is take off the old bumpstop and mount and seperate the two so you can use the stock mount with the new bumpstop. Zeus has photos of this: http://www.vehicross.info/gallery/sh...37/ppuser/1999
