The Spicer TTC needle bearing, part number 550991, is a transmission service component used in driveline and differential applications. Spicer TTC parts are produced under the Tremec/Spicer TTC line, and this bearing is also cross-referenced as SX550991. Needle bearings of this type provide rotational support in close-tolerance bores where a full rolling-element assembly would not fit. If you need to confirm this bearing is the correct fit for your transmission, give us a call at Pro Gear and Transmission and we can help you identify the right part.
