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.
Spicer offers new highly developed Gen-Tech™ quiet gearing for single axle applications that require low noise resolution while maintaining the same
high strength quality that Spicer
® genuine gearing is known for. This gearing like all Spicer gearing is developed and machined in sets and specified by
many customers in medium duty applications. Never mix gears and pinions from different sets within an axle. Shortened gearing life, noise and failure
may occur. When replacing gearing check the drive pinion and ring gear numbers to the charts below to get the correct replacement service kit.
