NSS – Not Sold Separately
Note: In mid-2004, the original design gearing kits were replaced by new gearing that contain design enhancements. In some cases when changing
certain ratios
(*ratios affected) or using new design gearing kits to replace original gearing, a differential flange half case change may be required. All
flange half differential cases are now available thru Spicer as individual components.
