Drag Specialties Engine Oil Filter Bracket

Drag Specialties Engine Oil Filter Brackets for Harley-Davidson V-Twins

Drag Specialties has been a cornerstone of the Harley-Davidson aftermarket world since 1968, and their engine oil filter brackets reflect the same dedication to fit, finish, and function that has defined the brand for over five decades. Whether you're restoring a classic Evolution Big Twin or refreshing a well-worn FX or FL model, Drag Specialties oil filter mounts are engineered to slot into your bike's existing architecture with minimal fuss.

OEM Replacement Oil Filter Mounts

At the core of the Drag Specialties oil filter bracket lineup is a direct OEM replacement mount designed for 1992–1999 Evolution Big Twin models. Built to replace the factory cast mount, it includes a 3/4"-16 oil filter adapter and is designed to install using OEM hardware — no fabrication or sourcing of specialty fasteners required. The mount features 11/16" threads to accept OEM hard oil lines, making it a seamless swap for riders looking to restore stock functionality or refresh an aging bracket. Available in both black and chrome finishes, it integrates cleanly with the engine without drawing unnecessary attention away from the rest of your build.

Offset Oil Filter Mounts

For riders running remote oil coolers or additional filtration setups on 1992–1999 Big Twins equipped with a front oil filter mount, Drag Specialties also offers offset oil filter mounts in chrome and black anodized finishes. These sandwich-style mounts provide 1/8" NPT ports (fittings sold separately) for easy hook-up to any style of remote oil cooler. Critically, they are engineered with a pressure relief valve rather than a standard thermostat — allowing constant oil flow through the remote cooler while protecting the engine from oil starvation. A rebuild kit is also available separately, including a replacement gasket, O-ring, and Allen-head hardware, so you can service the mount without sourcing individual components.

Why Drag Specialties for Oil Filter Brackets?

Drag Specialties has spent decades refining parts specifically for the American V-Twin platform, and their oil filter brackets embody that focused expertise. These are not generic universal parts — each bracket is developed for specific model years and engine families, referencing OEM part numbers where applicable so builders and restorers can be confident they're getting an exact fit. The choice of chrome and black anodized finishes means riders can match their bracket to the broader aesthetic of their build, whether that's a clean stock restoration or a blacked-out custom.
