Sorry Arizona_jay I missed this topic!!
I had the telescopic conversion on mine, but with the center lock in it didn't hold up as good as the stock metal shaft. I know there is a lot of wear on the GS094 brake drive cup when you have the center locked or not locked. But I wouldn't go for the telescopic conversion if you have the center diff locked!!!
Also if you have Spur Gear & Engine Plate Brace (gs097) on your genesis it will not fit!!
