4L60E HD Input Shaft 300mm w/ 15t Reluctor Wheel

Input shaft failure is a common problem in GM 4L60-E, 4L65-E, 4L70-E units as power levels are increased. Sonnax heavy duty input shaft 77733-12S for 300mm reluctor-style units is ideal for any high-horsepower street or strip application. The shaft is manufactured from a specially heat-treated steel with very hard outer layers and a more ductile inner core for strength and resistance to fracture. The feedholes are chamfered to reduce stress, and the shaft is further processed by shot peening and deep cryogenic treatment.

  • High-strength steel ideal for high performance applications
  • Shot peened and cryogenically treated for extreme durability
  • Unique design protects against failure from stress cracks
