Last night while installing my 5 way adjustable, I noticed the factory bump stop will not sit on the bump stop notch.Instead of "clipping" on the the notch like the KYBs, it just slides right through and rest on the top of the tube.
The KYB Gr-2 has the same design, with the exception of an additional 1 mm lip that allows the factory bump stop to rest on it, holding it in place.
I went on ahead and installed it with the bump stops resting on the top of the tube.
