DLC Coating Service for BMW S54 Cam Followers

This service allows BMW S54 owners to send in their cam followers (rocker arms) for professional DLC (Diamond-Like Carbon) coating at 5150 AutoSport. Customers remove their followers, wrap each one individually to prevent damage in transit, and ship them to us. We clean, inspect, and apply the DLC coating before returning them—individually wrapped and ready for reinstallation.

What is DLC Coating?
DLC (Diamond-Like Carbon) is a thin, ultra-hard coating applied to metal components to reduce friction, resist wear, and extend lifespan under extreme conditions. It combines the hardness of diamond with the lubricity of graphite, resulting in superior durability and performance.

Why DLC Followers for the S54 Engine?
The BMW S54 engine operates at high RPMs and uses a direct-contact cam follower design that places substantial load between the cam lobe and follower surface. Over time, this contact can cause wear or galling—especially with aggressive cams, high lift, or sustained track use. DLC coating dramatically reduces friction and surface wear, ensuring smoother valvetrain operation, consistent cam timing, and increased reliability under high-stress conditions.

Important Shipping Instructions:

• Wrap each follower individually to prevent scratching or impact damage during shipping.
• It’s uncommon to find a full set of 24 in perfect condition—send your entire set anyway.
• Our team will inspect each follower and contact you if any are unsuitable for coating. We can assist in sourcing replacements or core exchanges as needed.

This DLC coating service is a cost-effective way to preserve the integrity of your S54 valvetrain and enhance long-term engine performance.
