Valve covers are offered in two different mounting styles, the factory style clip on and aftermarket bolt on. Clip on valve covers use wire bales that hold the valve cover in place with tension. Bolt on valve covers come with hardware that bolts on to the rocker assemblies and provides the mounts for the bolt on valve covers. Bolt on valve covers are generally preferred off road as they are less prone to being knocked off by debris. We offer all the necessary mounting hardware and gaskets for either style valve cover.
Push rods tubes come in the recommended stock style compression tubes as well as adjustable, quick change tubes. For our own dune buggys we use the stock tubes almost exclusively. Quick change tubes are great for a quick trail fix if you happen to damage a tube on the trail and need to repair it to get back home. Push rods are come in various diameters and lengths to suit most common VW engine sizes. Don't forget to replace the push rod tube seals to help prevent a common leak.
Rocker assemblies bolt on to the head and transmit the push rods movement to the valve, rocking back and forth opening the valve and allowing it to close. Rocker assemblies are offered in 1:1, 1.25:1 and 1.4:1 ratios. 1.25:1 rockers are generally interchangeable with the stock 1:1 rockers but may require stand shims to maintain correct rocker geometry and push rod clearance. 1.4:1 rockers are only compatible with appropriate camshafts.
Stock valve covers, chrome plated valve covers and aluminum valve covers that are all held in place with the stock style spring bale. If using clip on valve covers off road make sure to safety wire the bales to prevent the clips from coming off.
For our own Baja Bugs we used bolt on valve covers for a secure mount. For added security safety wire can be used to ensure the bolts don't back out. We even offer Type 4 bolt on valve covers for those off road buggys with the late model Bus engine.
Stock cork, neoprene rubber and C-channel gaskets are available to fit all the different valve covers we offer. We even have replacement hardware for the bolt on covers if you've misplaced yours.
The only style push rod tubes we recommend for off road use, stock style one piece push rod tubes offer less places to leak when sealed correctly!
We only recommend the adjustable and quick change push rod tubes as a temporary fix. The 2 piece design is prone to leaking.
Chromoly push rod tubes are typically preferred over stock aluminum push rods. Chromoly push rods are less prone to flex and are adjusted with zero valve lash.
Rocker arms are bolted to the rocker shaft and open the valve when pushed by the pushrod at the bottom side. Valve adjusters are used to set the valve adjustment. 1:25 and 1:4 to 1 rockers allow the valves to open further increasing air flow which increases horsepower.
