Pioneer Cables 639871 Engine Torque Strut Mount

Pioneer Cables 639871 is a specific-fit engine torque strut mount for the lower position on select Toyota Prius C models. It uses a rubber bushing and is built to meet or exceed original equipment manufacturer requirements for fit and function.

Key Features

  • Specific-fit engine torque strut mount for direct application matching
  • Rubber bushing material for controlled engine movement and vibration isolation
  • Five mounting holes for application-specific attachment points
  • Meets or exceeds original equipment manufacturer standards
  • Fits 2012-2017 Toyota Prius C, lower
  • Part number 639871 for accurate ordering and cross-reference

Detailed Description

This Pioneer Cables engine torque strut mount is engineered for the lower mount location on 2012-2017 Toyota Prius C models. The rubber bushing helps manage drivetrain movement while maintaining the alignment and support expected from an OE-style replacement. If you are replacing a worn Toyota Prius C lower torque mount, 639871 provides a direct-fit solution for the specified application.

This part cross-references Anchor 9871 for the same application.

What It Helps Address

  • Excess engine movement during acceleration and deceleration
  • Clunking or knocking noises from a worn lower torque mount
  • Vibration transfer into the cabin from deteriorated rubber
  • Misalignment caused by a fatigued engine support mount
  • Restoring stable engine positioning on Toyota Prius C applications

Installation Notes and Tips

Verify the vehicle is a 2012-2017 Toyota Prius C with the lower mount configuration before installation. Confirm the mounting hole layout matches the original part and inspect surrounding brackets and fasteners for wear or damage. Because this is a specific-fit component, compare the old mount to part number 639871 before removal to confirm correct application.

Quality Assurance

Pioneer Cables states that this mount meets or exceeds original equipment manufacturer requirements. That specification supports OE-level fitment expectations for the listed Toyota Prius C application.
