Description
The Billet Specialties Ball Milled Style Window Cranks upgrade your classic vehicle's interior door panels with modern machining precision and a high-tech custom look. CNC-machined from solid 6061-T6 billet aluminum, these full-length manual window cranks feature Billet Specialties' signature ball-milled groove pattern running along the handle arm.
Sold in pairs, each crank incorporates a hardened steel spline insert held firmly in place with dual set screws, providing a durable, slop-free connection that prevents the mounting splines from rounding out over time.
Key Features & Design Highlights
Aircraft-Grade Billet Aluminum: CNC-machined from solid 6061-T6 aluminum for maximum structural rigidity and long-lasting performance.
Dual Show-Quality Finishes: Available in an award-winning high-luster Mirror Polish or a sleek, durable Black Anodized finish.
Steel Spline Insert Architecture: Features high-strength steel splines housed inside the billet aluminum hub, locked down with two concealed set screws to eliminate slop and prevent stripping.
Full-Length Lever Profile: Measures 4-13/32" from the center of the spline pivot to the tip of the handle for comfortable leverage when raising or lowering windows.
Direct Bolt-On Upgrade: Installs in minutes using basic hand tools to replace worn or pitted factory pot-metal cranks.
