Heavy Duty Input Shaft
Part No. 77733-11S

Fits 300mm non-reluctor style units only.

Input shaft failure is a common problem in GM 4L60-E, 4L65-E, 4L70-E units as power levels are increased. The Sonnax heavy duty input shaft 77773-11S for 300mm non-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 feed holes 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
