| This is the front seal or pinion seal for the R200 differential. Uses 1 per vehicle. Always be sure to double check the style of differential that you have in your z before ordering parts. For identifying by picture, which diff you have just go to Used Differentials and look at the pics for the 2 styles. There is the R180 and the R200. We now sell an LSD conversion kit for both models of z car differentials. See listings. If we happen to be out of stock please allow an extra week for delivery. Last update 12/11 |
