Product Description
FLEECE FPE-BRAB-D1 32V DURAMAX ROCKER BRIDGES
The FLEECE FPE-BRAB-D1 32V Duramax Rocker Bridges deliver the durability, accuracy, and valvetrain stability required for high-performance 2001–2016 6.6L LB7 / LLY / LBZ / LMM / LML Duramax engines. Manufactured from heat-treated billet material and precision-machined for consistent contact geometry, these rocker bridges provide the strength needed for high boost, aggressive tuning, elevated RPM, and upgraded valve springs. Designed as a superior replacement for worn or flex-prone factory bridges, they maintain correct valve motion under load, improving reliability in both street and competition Duramax applications.
Key Features
- Precision-machined billet construction: Ensures consistent rocker-to-valve contact across all 32 valves.
- Increased valvetrain stability: Ideal for high boost, performance tuning, and elevated RPM.
- Superior strength: More rigid than factory bridges, reducing flex and valve motion loss.
- Direct replacement: Fits OEM rocker pedestals and rocker arms without modification.
- Improves longevity: Excellent upgrade when refreshing worn valvetrain components.

Why Upgrade Duramax Rocker Bridges?
OEM rocker bridges are prone to flex and uneven contact during high load, high boost, and high RPM operation. The FPE-BRAB-D1 set eliminates that weakness with a stronger, more consistent billet design. For tuned, towing, compound turbo, or competition setups, these bridges help maintain reliable valvetrain geometry, preventing power loss and long-term wear.

FAQ
Yes — the FPE-BRAB-D1 bridges fit all 32-valve 6.6L Duramax engines from 2001 through 2016, including LB7, LLY, LBZ, LMM, and LML.
Are these stronger than factory Duramax rocker bridges?
Absolutely. These billet bridges provide improved rigidity and strength under high boost, preventing flex and maintaining proper valve motion in performance or towing applications.
Do I need upgraded pushrods with these bridges?
While not required for stock applications, Fleece Stage 2 pushrods are highly recommended for high boost, larger turbos, aggressive tuning, or towing performance.
Is any modification required for installation?
No. These bridges install as a direct OEM replacement using stock rocker pedestals and rocker arms.
Are these suitable for competition Duramax builds?
Yes — they are ideal for drag racing, sled pulling, high boost, compound turbos, or any high-performance Duramax application.
