What's it called?

M8 of mine will be replacing the bushes but not sure what they are called. They are above and forward of the rear diff, connected to two rods running the same direction as the rear axle. They support the diff. Any help in identifying them would assist as he doesn't know what to ask for. Cheers guys.

trailing arms at rear or suspension arms at front

They are not the trailing arms, they are forward of and above the rear diff unit. Thanks for the replies.
