FR500 Differential Bushing

[ChrisM]

I've been trying to track down what kind of differential bushing the FR500 cars run but haven't been able to dig anything up. Does anyone have that information? I know we've got some owners here. I appreciate your help!

Came with stock Ford OEM 2008 Mustang GT diff housing bushing.

Huh. I figured that might be why I couldn't find any mention of it. I wonder why? Thanks for the info!

I think the main reason is cost. Ford has to have a very good reason to change a part like that when considering that they stock complete rear axle assemblies. Changing just the bushing would add another assembly part number/etc. I doubt the bushing is changed on the 302S or 302R also, for the same reasons. I think only the upper arm and upper/front bushing was upgraded with the spherical.
