CB Performance Pro-Series Adjustable Push Rod Tubes offer a unique Snap-Ring Adjuster as opposed to typical jam-nut designs. This allows for quick and easy adjustability by just moving the snap-ring in 1/4" increments, from stock width to 1/2" narrower and up to 3/4" wider.

Another feature unique to the Pro-Series tubes is that they utilize "tried-and-true" Silicone Push Rod Tube Seals, so no need to hunt down custom O-rings that stop sealing after they go flat with heat and age.

The Pre-Loaded Spring allows consistent tension, regardless of engine width variations common to VW engines as they heat up and expand, then cool down and contract.

Fits Type-1 Upright Aircooled Engines only, and features an oversized 7/8" ID to accommodate up to 1.5:1 Ratio Rockers!

Optionally, the Pro-Series tubes can be installed without removing the cylinder heads. Just remove the rocker block and push rod, rip out the old tube/seals and install a Pro-Series tube per instructions.

NOTE: This is a replacement tube, and is sold individually. CBP also offers Pro-Series tubes in complete sets of 8.
