Description
Product Overview
Upgraded billet aluminum fuel filter head designed as a direct replacement for the failure-prone OEM plastic filter housing on 2001-2016 Chevy Silverado and GMC Sierra HD trucks with the 6.6L Duramax (LB7, LLY, LBZ, LMM, LML). The factory plastic housing is notorious for cracking, warping, and stripping threads — leading to fuel leaks, air ingestion, and no-start conditions. Our CNC-machined 6061-T6 aluminum head permanently solves these issues.
Key Features
-
Solid Billet Aluminum: CNC-machined from 6061-T6 aluminum — eliminates cracking, warping, and thread stripping common with OEM plastic housings.
-
Precision Threads: Rolled stainless steel insert threads — no more stripped plastic threads preventing proper filter seating.
-
Upgraded WIF Port: Machined Water-In-Fuel sensor port with stainless threads — maintains factory warning system without OEM port cracking.
-
Direct Bolt-On: Factory mounting points, exact OEM dimensions — installs in 30-45 minutes with basic tools.
-
Lifetime Durability: Permanent upgrade that will outlast the truck — unlike OEM plastic housing that may fail repeatedly.
