Good to Know, i had to look the pliers up, I always called them snap ring pliers but I see they actually can also be called Circlip, rotor clip, Jesus clip,It is a billet item that uses the OEM inner assembly from the stock cap. You only need a C-clip pliers to remove and install the insert.
There are knock-offs from China on eBay but they don’t look that great in the pictures. The RSD cap is very well made.
