Double-ended aluminum AN Wrench 8AN Nut-10AN Nut

The Double-ended aluminum AN Wrench 8AN Nut-10AN Nut from REDHORSE PERFORMANCE is an essential tool for any serious automotive builder working with AN (Army-Navy) hydraulic fittings and brake lines. If you're installing a custom fuel system, upgrading your brake setup, or fabricating a race-spec cooling circuit, you need a dedicated AN wrench that won't round off your precision fittings.

This dual-end design eliminates the need to carry multiple wrenches, saving space in your toolbox while delivering the exact sizing required for 8AN and 10AN connections—the most common sizes in high-performance automotive applications. The wrench is made from aluminum, providing a lightweight option that fits into tight engine bay spaces without the weight penalty of steel alternatives. Each end is precisely machined to grip 8AN and 10AN nuts with a hex pattern that prevents stripping, a common problem when using adjustable wrenches or standard SAE tools on AN fittings.

This wrench is indispensable for LS engine swaps, fuel system upgrades, and custom radiator installations. REDHORSE PERFORMANCE's reputation for precision sizing ensures zero wobble and maximum contact surface, reducing the risk of cosmetic damage to polished or anodized fittings during installation or removal. Its 10.75-inch length makes it ideal for overhead work or confined fabrication areas.
