The valves work in tandem with a single remote, as advertised. However, the quality is lacking. The valves will rattle with the engine vibration after being left in the same mode for a while. The rattle is noticeable and sounds like metal on metal clanking. It goes away as soon as you operate the valve to open or closed again. But it will return in less than a day if left untouched.

Dear Customer, Thanks for your genuine feedback! We apologize for the recurring rattling noise from loose valve parts under engine vibration. Our factory will revise the internal locking structure to fix this issue on future units. Reach out to our support team for warranty replacement if needed.

Terrible customer service. Can't speak to a live person. Their instructions are not very detailed. They miss several steps just all the way around a terrible install. I could have wrote instructions for this even though this is the first time I've ever done it. Sorry to say but the truck does run good

Well manufactured cnc billet aluminum ccv block and good quality hardware to replace the failure prone GM design on the L5P duramax that uses boost pressure. Spelab does not have this risk of pressurizing crankcase and no components can ever fail. Also nest price of similar kits and fast shipping.

Dear Customer， Thank you so much for this detailed review of our CNC billet aluminum CCV block for L5P Duramax! We designed this unit to eliminate the well-known failure points of the stock GM CCV system and prevent crankcase pressurization under boost. It means a more reliable setup with zero vulnerable internal components. We truly appreciate your recognition of our solid build quality, complete hardware package, competitive pricing and fast shipping. Thanks for choosing SPELAB, we look forward to supporting your future truck builds! Best regards, spelabautopart Customer Support Team [email protected]
