Urethane engine mounts..... but these are different....very different. Everyone is just selling a bushing or the full steel mount ones. These ones are dual bushings on each mount and look very impressive. It looks as though a lot of work was put into these. Supposedly it will alleviate shock through the 2 bushings in each mount. So you'll actually get 4 engine mounts as opposed to a regular 2. These should be far superior to anything that is available, so I've been told. I am putting a set in my engine going in my Z here this week. I'll let you know how everything works out and when to expect a GB on em.
