You also get delrin spring housing
This is a good product by critical, I've had it for a year now and it hasent broke, and threw that year I've seen probably 20+ broken drive cones. Every time i see that i say get the critical one. Also the delrin spring housing is a plus, so now that cant break eather. The cone is light in weight, i had one from another manafacture and it was super heavy so i got rid of it for this one.
Its a solid product and worth the money. If your stock cone is broken get this one, if your worried about your stock one breaking get this, if you dont have this one get it.
