DSM/EVO 1-3 4G63 Valve Cover

These valve covers start life as a 36lb hunk of 6061 aluminum, and after many hours of machine time on our in-house Okuma machining center, they come out like this. You don’t have to be shy about tightening down these like the stock cast pieces. You can tighten them down as much as you want as long as you don’t snap the bolts off in the head!  The streamlined profile of these covers allows us to place the baffled -10AN ORB breather ports right on top of the valve cover for maximum flexibility in routing of breather lines.  The -20AN oil caps ensures that leaky oil caps will not be an issue anymore.

Please note... If product is not listed as in stock, there may be a lead time of up to 8 weeks. Please contact via email with any questions regarding lead times on specific products. As we are a small operation, it is tough to keep everything in stock, and we typically only run a batch of something if there are a few backorders placed. With that being, said, we do try our best to run extras, and intend to stock everything as soon as capacity allows. Thanks for everyone's understanding and patience!
