OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

Bugpack Serpentine Belt and Pulley Kit, 6 3/4" Black Anodized, 4512-70
Bugpack Serpentine Belt and Pulley Kit, 6 3/4" Black Anodized, 4512-70


 
Bugpack Serpentine Belt and Pulley Kit, 6 3/4" Anodized, 4512-70. The crank pulley is held to hub with 6 Allen Bolts, so you can remove the pulley for tin screw access! This kit uses a FULL SIZE crankshaft pulley for maximum cooling!

Bugpack has really put a nice kit together here, with all needed parts included. Kit comes with the Crank and Alternator/Generator Pulleys, the Crank Pulley HUB (which is well thought out), Idler Bracket, High Quality Idler Bearing and Idler Adjuster, and all hardware. Everything except the bearing is black.

Serpentine belts do not slip nor flip, they are more efficient than V-belts. However, because they do not slip we do NOT recommend that you use a Serpentine belt if your engine's RPMs exceed 6000, it over-speeds the fan, since it doesn't slip like a V-belt does. This exposes the fan to more RPMs and they often blow-up. So a Serpentine belt system is GREAT for Cruisers (especially busses) that tend to run hot, you get maximum cooling airflow with a Serpentine Belt System.
