Pioneer Automotive PB-11 Pilot Bushing

The Pioneer Automotive PB-11 is a precision-manufactured pilot bushing (also referred to as a pilot bearing or crankshaft pilot bushing) designed to support and center the transmission input shaft or torque converter hub within the crankshaft bore. This small but critical component ensures proper alignment between the engine and transmission, reducing wear and vibration during operation.

Key Features:

• Precision-machined to exacting tolerances for a secure, accurate fit in the crankshaft or flywheel bore
• Manufactured from durable materials to withstand heat, friction, and continuous rotational stress
• Supports and guides the transmission input shaft, maintaining proper concentricity
• Direct-fit replacement for worn or damaged OEM pilot bushings
• Engineered to meet or exceed original equipment specifications

The pilot bushing is a commonly overlooked component during clutch and transmission service, but replacing it at the time of a clutch job is strongly recommended to prevent premature input shaft wear. The Pioneer PB-11 provides a reliable, cost-effective solution for professional technicians and DIY enthusiasts alike.
