A genuine OEM brake booster AND master cylinder assembly for a Jaguar XK8/XKR from 1997-2002, I believe. It is in good overall condition both mechanically and cosmetically and was working solidly upon removal. Additionally, this also includes the mounting frame/pedal housing and the large pin on top. And furthermore, this particular part only has 68,8K on it! Definitely lots of value here, certainly more than you're gonna find elsewhere. Ships from the USA and comes with a 30 day money back guarantee.
