GEATaaT 18-760 is a replacement outer cover made for Ness Billet Sucker and Big Sucker stage air filter kits to protect, seal, and style compatible Harley‑Davidson models.

This outer cover is designed as a direct-fit cosmetic and protective piece for a wide range of Harley‑Davidson cruisers and touring bikes. Machined from robust aluminum and finished for weather resistance, the cover shields the exposed filter element, keeps debris and moisture at bay, and complements aftermarket Billet Sucker and Big Sucker installations. Installation is straightforward: it replaces the original cover and secures with the supplied screws so you can get back on the road quickly.

Which motorcycles will this cover fit?

The 18-760 cover fits many Harley‑Davidson models when paired with Ness Billet Sucker or Big Sucker stage air filter kits. Check your model year and filter compatibility before ordering to ensure a precise match.

• Compatible with a long list of Harleys including Dyna, Softail, Sportster, Road King, Street Glide, and more.
• Works specifically with Billet Sucker and Big Sucker stage filter assemblies (not universal filters).

How does this cover protect the air filter on the road?

The outer cover creates a barrier that reduces direct contact with road debris, rain, and grit while still allowing airflow through the filter assembly. Its aluminum construction resists dents and corrosion better than thin stamped covers, helping the filter maintain performance and appearance longer.

• Shields the filter external surface from stones, bugs, and wind-driven dirt.
• Waterproof and dust-resistant finish helps limit moisture and particulate intrusion.
• Sturdy material reduces deformation from impacts compared with weaker covers.

Is installation difficult for a home mechanic?

Installation is designed to be simple and tool-light: remove the old outer cover, align the new cover over the filter element, and secure it with screws. No complex adjustments or additional parts are required when used with compatible Billet Sucker or Big Sucker kits.

• Direct replacement—uses existing mounting points and screw hardware.
• No need to modify the intake or filter assembly when compatible.
• Typical install time is a few minutes for someone comfortable with basic hand tools.

What materials and finish should I expect?

The 18-760 is fabricated from high-quality aluminum and finished to resist weather and road debris. The cover is tested for basic durability and treated to help prevent rust and surface wear during normal use.

• High-grade aluminum construction for strength and light weight.
• Weather-resistant coating to reduce corrosion and staining.
• Precision machining for a clean fit and attractive appearance on the bike.
