This mod replaces the factory plastic pushrod eye with a 6061 billet aluminum piece and high strength set screw, creating a tight connection that will never wear out.
The plastic bushing is notorious for wearing down and/or cracking and breaking,allowing for excessive play between the pushrod and even extreme cases the factory clutch rod end breaks completely leaving you stranded on the side of the road.
If your Ford Mustang master cylinder rod has a hole, you can use it directly, but if your master cylinder stem don't have a hole into it for the supplied pin, you need to drill a hole to use it properly.Highly recommend installed by professional!!
You'll be amazed at how such a simple modification can greatly improve clutch feel.
