BMW F30 340i Belt Tensioner Pulley

SKU F30-340I-TENS
Price

$104.99

The belt tensioner pulley maintains proper tension on the serpentine belt so it drives accessories without slipping or squealing. A worn tensioner leads to belt noise, vibration, or premature belt failure.

This tensioner is designed to fit the BMW F30 340i (N55 turbo inline-six), matching the OEM mounting bolt pattern and pulley diameter.

A quality bearing and spring assembly restore smooth, consistent belt tension and quiet operation.

Reference: OE/interchange ULTRA-POWER

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
