Pump Shaft with Bearing
1984 & later
Sonnax pump shaft 75877A is a direct replacement for late-model GM 3T40 (125C) shafts from '84-later. The Sonnax shaft is made of higher grade steel than the OE to improve wear resistance of the spline surface, and the shaft incorporates a solid steel collar in place of the OE stamped metal collar.
