Here at Chirco performance we offer our customers several styles of push rod tubes, our pushrod tubes are offered individually as well as in complete sets, our adjustable Air Cooled Volkswagen push rod tubes are offered into styles, threaded in spring-loaded, some performance Volkswagen engine builders prefer the spring-loaded over the threaded as they will allow for movement as the engine heats up to temperature preventing leaks from the pushrod tubes seals.
They have always had exactly what I have needed from my 1965 Baja, to my 1974 super, always willing to give advice, the staff knows their stuff, and they have a large stockpile of parts, the only place I get my VW parts.
Regardless of whatever else I've had for cars I've always had at least one VW. Reliable and easy to work on. Chirco is without question the best place around Tucson to get quality VW parts and service.
