EAPP Battery Fuselink and Positive Terminal Assembly AL3Z-14526-AA 250A/125A Direct-Fit for Ford F-150 F-250 (2011–2014) OEM-Style

This EAPP EDS AL3Z-14526-AA is a direct-fit OEM-style 250A/125A battery fuselink and terminal assembly built to restore factory electrical protection and reliable power delivery for compatible Ford trucks.

If your Ford truck is showing intermittent starting, blown fuselinks, corroded battery terminals, or degraded main power protection, this replacement assembly returns the system to factory-spec performance. EAPP supplies the fuselink and matching positive terminal engineered to replace part AL3Z-14526-AA and BT4Z-14450-AA, offering the correct ratings, hardware, and installation pieces. The kit targets common failure points in the main battery feed—where high-amperage circuits demand a robust connection and precise fuse protection.

Which vehicles will this fuselink and terminal fit?

This assembly is made to fit a range of Ford trucks from the early 2010s. It is a direct-fit part intended for F-150, F-250, and related models listed by Ford, matching OEM dimensions and mounting points so the replacement installs without modification.

• Direct compatibility with Ford F-150 (2011–2014) and F-250 (2011–2014)
• Also fits Lobo (2011–2014) and Mark LT (2011–2014) where the same factory parts were used
• Matches factory terminal BT4Z-14450-AA and fuselink AL3Z-14526-AA specifications
• Designed for a bolt-on swap using existing battery tray and cable routing

How does the dual-rating 250A/125A fuse protect my truck?

The fuselink uses two current ratings to guard different parts of the main power circuit. In normal operation the higher 250A path handles startup and alternator loads; the 125A rating protects subordinate circuits and provides a predictable failure point under overload conditions.

• 250 Amp capacity for starter and primary high-load events
• 125 Amp protection for secondary circuits and controlled failure modes
• Reduces risk of wiring damage by providing a factory-style sacrificial link
• Engineered to interrupt safely under sustained overloads to protect downstream components

What comes in the complete installation kit and how easy is the swap?

The kit includes everything required for a secure, professional install so you won’t need to source separate parts. Components are packaged to replace both the fuselink and the positive battery terminal, plus hardware and heat-shrink for corrosion-resistant connections.

• Fuselink AL3Z-14526-AA (250A/125A) and BT4Z-14450-AA positive battery terminal
• Three 6mm nuts, one 8mm locking nut and heat shrink tubing for insulation
• Direct-fit design for fast bolt-on replacement by a technician or experienced DIYer
• No cutting or splicing required when replacing like-for-like factory parts

Why choose this EAPP assembly over aftermarket alternatives?

EAPP manufactures this assembly to OEM standards, emphasizing dimensional accuracy, material strength, and consistent electrical performance. Choosing a unit that mirrors factory engineering helps maintain the truck’s designed safety margins and simplifies service by preserving original mounting points and ratings.

• Built to OEM manufacturing standards in Mexico for consistent quality
• Designed to meet original electrical and mechanical specifications
• Includes the exact hardware set used in factory installs to speed reassembly
• Reduces troubleshooting by restoring known factory configurations

Who is this for: This EAPP fuselink and terminal assembly is intended for Ford truck owners, fleet managers, and automotive technicians needing a reliable, factory-spec replacement for worn or damaged battery fuselinks and terminals. It’s suitable for anyone restoring electrical reliability in affected F-150, F-250, Lobo, or Mark LT models from the 2011–2014 model years, or for professionals who prefer OEM-fit components for repairs and preventative maintenance.
