This guide joins the factory catalogue reference to the exact products documented below. It does not certify interchangeability or provide manufacturing dimensions.
Weight, dimensions and material
Each specification below names the exact product it describes. Alternative-part values are not measurements of the Genuine Porsche part. Missing properties are not estimated.
Weight
Not published by the cited source
Applies to: Rothsport Racing RS-164B · aftermarket performance
The current indexed canonical Design911 product page identifies Rothsport RS-164B, explicitly lists 96410651102 and 96410626700 as replacement references, states Porsche 964 and 993 fitment, and specifies CNC-machined 7075 aircraft alloy with hard anodising. Live gstack Chromium receives the site security challenge; the connected Chrome broker became unavailable after the first navigation attempt, so no challenge was bypassed.
The product page says the pulley is approximately half the factory-part weight but publishes no numeric piece weight; no estimate or shipping weight is substituted.

Where to buy
Check the VIN, variant, quantity and installation requirements before ordering. Availability is a dated observation, not a delivery guarantee.
Live gstack Chromium reaches the exact-reference Genuine Porsche page, reports Available, publishes a current price and exposes Add to cart. The retailer lists this M64.01 half pulley for 1989-1994 911 applications.
The current indexed direct product page identifies Rothsport Racing RS-164B, fits Porsche 964 and 993, cross-references 964 106 267 00 and describes a CNC-machined 7075-alloy, hard-anodized pulley half at approximately half the factory-part weight. Live gstack Chromium and the connected Chrome session reach the canonical URL but cannot extract the protected page directly.
Original-equipment manufacturer
No historical original-equipment manufacturer has been verified for this reference. A replacement brand alone does not establish who supplied Porsche production.
Fitment and research notes
Rothsport Racing RS-164B is documented as a performance alternative, not as a Porsche production-supplier reference. The Porsche retailer page gives narrower M64.01 and 1989-1994 fitment than the Rothsport 964/993 listing: confirm engine, pulley hub, belt arrangement, offset and all companion pulley references before ordering.
