Quoting Eaglesfly:
Any idea if these would work with DSM D2's (so they could be used properly on a VR-4)?
The strut rod on the K-sports, and given the previous comment, presumably the D2's, is smaller at the very top than is the AGX or stock strut rod. The bushings are milled out to accommodate this new diameter. As to if they would work? They would probably work on anything, but the bushing would have to be changed, possibly.
