Ford Mustang Cobra / GT / LX & Lightning Billet Aluminium Smog Air Pump Idler Bracket Delete Kit with Pulley 1979 - 1995 (5.0L / 5.8L)

Permanently delete the smog air pump on your Ford Mustang or Lightning 5.0L / 5.8L with this premium billet aluminium smog pump idler bracket and pulley kit, precision crafted from aircraft-grade aluminium for permanent durability and a clean engine bay aesthetic. The factory smog (secondary air injection) pump is one of the most commonly deleted components on Fox Body, SN95, and Lightning builds — it adds parasitic drag on the accessory drive, robs horsepower, adds weight, and creates engine bay clutter that serious performance enthusiasts eliminate as part of any meaningful build. This billet aluminium idler bracket and pulley kit replaces the smog pump entirely, freeing up horsepower, reducing front-end weight, and routing the serpentine belt cleanly through an idler pulley that maintains factory belt length and tension. Featuring a heavy-duty double-row ball bearing pulley for increased angular load capacity and durability, this kit is built to handle sustained high-RPM operation without bearing failure.

Features:

• Premium billet aluminium construction – delivers exceptional strength, lightweight performance, and long-term durability
• Smog pump delete solution – eliminates the parasitic drag, weight, and engine bay clutter of the factory secondary air injection pump
• Double-row ball bearing pulley – significantly increased angular load capacity and durability compared to single-row alternatives, designed for sustained high-RPM operation
• Heavy-duty support shaft – provides superior bearing support and prevents premature wear under sustained accessory drive loads
• Factory belt length compatibility – pulley sized identically to factory smog pump pulley to maintain original serpentine belt length and tension
• Pre-machined corner clearance – no grinding or modification required for proper installation against the engine block
• Direct retrofit upgrade – designed specifically for Fox Body and SN95 Mustang and Lightning factory accessory drive layouts

Contents:

• 1x Billet Aluminium Smog Pump Idler Bracket
• 1x Double-Row Ball Bearing Pulley

Benefits:

• Permanently eliminates the parasitic drag of the factory smog pump – freeing up horsepower that the smog pump consumes from the accessory drive system
• Reduces front-end weight by eliminating the heavy factory smog pump assembly – every weight reduction matters for serious performance Mustang builds
• Cleans up the engine bay – removes one of the most visually cluttering factory components, creating space for cleaner intake routing and engine bay aesthetics
• Double-row ball bearing pulley delivers significantly higher load capacity and bearing life compared to factory or budget alternatives – critical for sustained high-RPM operation in performance builds
• Maintains factory belt length – the matching pulley diameter eliminates the need to source a different serpentine belt, simplifying installation
• Pre-machined corner clearance eliminates grinding work during installation – ready for direct bolt-on fitment without modification
• Significant cost savings compared to replacing the factory smog pump as it ages and fails – this delete kit is a one-time permanent solution
• Foundation product for serious Fox Body, SN95, or Lightning performance builds – pairs naturally with cold air intakes, headers, and ECU tuning for comprehensive performance upgrades

Installation Notes:

• Emissions compliance verification: Smog pump deletion may not be legal in all jurisdictions for street-driven vehicles. Verify local emissions regulations before installing this kit on a street vehicle. This product is intended for off-road, race, or competition use where emissions compliance is not required
• Allow the engine to fully cool before beginning installation to avoid burns from hot engine components
• Document the original serpentine belt routing before disassembly – take photos of the belt path before removing the factory smog pump
• Carefully remove the factory smog pump assembly – disconnect any vacuum lines, electrical connectors, and exhaust connections before removal
• Cap or plug any exhaust manifold smog passages after smog pump removal – ports left open can affect exhaust system function and create vacuum leaks
• Install the new billet idler bracket using factory smog pump mounting points and hardware
• Mount the double-row bearing pulley to the bracket and verify proper alignment with the serpentine belt path
• Reinstall the factory serpentine belt following the original routing path – the matching pulley size maintains correct belt length and tension
• Verify smooth, quiet accessory drive operation after engine startup – any unusual noise indicates installation issues requiring inspection
• Address any check engine lights or smog-related diagnostic codes that may appear after smog pump removal – may require ECU tuning or code suppression for fully clean operation
• Installation instructions not included: Professional installation strongly recommended unless you have experience with Fox Body / SN95 accessory drive service procedures
• If unsure about compatibility with your specific Mustang or Lightning variant, contact our team with your year, model, engine displacement, and accessory drive configuration before ordering

Warranty:

• 12-month standard warranty from date of purchase
• Contact our support team for assistance with any issues
