Yes they are GPM Ti front CVD's I'm not too sure about them, they dont seem fit particulary well. Normally a cvd pushes up against the inside knuckle bearing - these dont. (theres around a 5mm gap!) I put a standard maxx wheel bearing on the cvd before fitting to space it correctly. I also used a shim to protect the two bearings together, i'm not sure how it will work out though. They come left and right hand threaded which is also a bit of a pain.

The rear Ti cvd's are great - they fit and run well, sorry I'm not sure the manufacturer, I though they were GPM too, but they dont come with cups which seems silly.
