FAQ
Will this oil cap fit my Duramax?
Yes. The FPE-DMAX-OC-BLU is designed as a direct replacement oil cap for 2001-2016 GM 6.6L Duramax engines (LB7, LLY, LBZ, LMM, LML) in Silverado and Sierra 2500HD/3500/3500HD trucks that use the factory-style screw-in oil cap.
Do I need any special tools or tuning to install it?
No special tools or tuning are required. Simply remove your factory oil cap and install the Fleece billet cap with the supplied O-ring and cam-lock. Make sure the O-ring seats properly and the cap is fully locked for a proper seal.
Is this just a cover or a complete replacement cap?
This is a complete billet aluminum replacement oil cap designed to replace the factory oil filler cap. It provides the same function as OEM while upgrading the look and feel of your engine bay.
Will the blue anodized finish fade over time?
The anodized finish is designed for durability in high-heat environments. Normal under-hood use will not affect performance, but as with all anodized parts, prolonged exposure to harsh chemicals or abrasive cleaning can dull the finish over time. Clean with mild soap and water only.
Is this product emissions or street-use restricted?
No. This billet oil cap is an appearance and service component only. It does not alter emissions equipment or tuning and is suitable for on-road use. Always review and comply with local regulations.
