Engineers at TCI® utilized cutting-edge manufacturing techniques to create new ultra durable 700R4 Input Shafts (4L60E also available - Part# 379601) that won’t twist or break under the stress of high horsepower applications that utilize a 700R4 transmission. The shafts are made from a heat-treated, billet 300M material with a higher yield strength that resists breakage and results in less shaft twisting than OEM material. Precision ground shaft ensures smoother bushing surfaces than inferior machine turned shafts. Rolled splines stop unnecessary hobbed areas that occur when cut with a gear hob. This increases the strength and density of the material in the splined areas because rather than removing material, the splines are actually compacted, which causes the material to be more dense in this area. These new Input Shafts are a must for high-horsepower applications that utilize a 700R4 transmission to eliminate the input shaft breakage issues common in lesser quality products.

Features & Benefits:

  • Precision ground shaft ensures smoother bushing surfaces than inferior machine turned shafts
  • Rolled splines eliminate hobbed areas while increasing density & strength in spline areas
  • Heat-treated, billet 300M material won't twist
  • Eliminates input shaft breakage in high horsepower applications using 700R4 transmissions
