Product Questions

I have a 2002 GT mustang with 4.6 I am putting 315-35-17 tires on 10.5 American Bullit mags on back. Will this shock work without rub or would it have to be flipped?

Asked by: NomadNomlaki
A lot will depend on the offset of the wheel, but if you have a typical and popular offset like +23mm - +28mm on your 10.5" Wheel, you should be just fine as is. If your car is extremely lowered, you may have to flip the shock.

Do I need to purchase rubber bushings with this product?

Asked by: ZachJ
No the bushings are already installed in the shock.
