Do these have ANY give at all or are they totally solid. I see there looks to be a delrin piece involve, but I can't really tell from this picture where things go. I want something that has much less give than factory, is not an insert, but I think aluminum/solid isn't necessary for my application.

  • The Ford Performance Rear Differential to Subframe Bushing Kit will come with steel, aluminum, and delrin bushings. While all solid, delrin will allow the most bushing flex, followed by aluminum and then finally steel with the least flex, these will provide a harsher ride than stock.

    Its genuine

    Two big things this products offer is that it comes with Rear Differential to Subframe Bushing Kit and it Eliminates Rear Differential Movement which is a big plus.
