Full model list at the end of this description.

⚙️ Key Features

• Hardened precision-ground shaft and splines
• Bearing journals matched to the upper-gear housing
• Transfers torque between the input and driven gear sets
• Requires correct shimming and bearing preload
• Drive ratio, gear set and serial number must match

🔌 Function

Carries the upper-gear train and transfers torque between the input shaft and vertical drive train.

⚠️ Common Signs of Failure

• Gear whine, rumble or knocking
• Pitted splines or worn bearing journals
• Excessive end play or incorrect gear contact
• Bearing overheating or shaft scoring from water-contaminated oil

🛠️ Service Notes

• Confirm drive ratio and gearbox serial number before ordering - this DPS-B1 upper-gear shaft is shared across a very wide span of V6 and V8 engine/drive combinations that are not interchangeable on ratio alone
• At 2.177 kg this is one of the lighter shafts in the wider countershaft range, consistent with a DPS-B1 upper-gear position rather than a heavier lower-gear shaft from a different drive generation - double-check the drive generation if a noticeably heavier shaft is ever offered as an alternative
