Door Lock Knobs Tri-Five Smooth Black Pair

The Door Lock Knobs Tri-Five Smooth Black Pair by Billet Specialties delivers classic American automotive styling for enthusiasts restoring or customizing 1955–1957 Chevrolet models. Designed specifically for tri-five platform vehicles, these door lock knobs provide an authentic, period-correct appearance while maintaining functional reliability. Whether you're completing a show-quality restoration or upgrading an existing interior, this pair replaces original hardware with precision-engineered alternatives that blend heritage aesthetics with modern durability.

Crafted from aluminum and finished in black anodize, these door lock knobs measure 1-5/8 inches tall and feature a smooth, refined surface that complements both stock and customized interiors. The 10-24 threaded fastener ensures secure mounting to factory door panels without modification, while the anodized coating resists corrosion and UV fading typical of interior automotive environments. The compact 2.6 x 0.65 x 6.05-inch profile fits factory door cavities precisely, maintaining proper door operation and latch engagement with no interference or binding.

Tri-five owners undertaking frame-off restoration, partial updates, or detail refinishing benefit most from this matched pair, which ensures visual consistency across both driver and passenger doors. Installation requires only hand tools and takes minutes per door—no drilling, cutting, or panel modification needed. Billet Specialties' reputation for fit and finish in the classic Chevy market makes these knobs a trusted choice for builders and restorers seeking OEM-quality appearance with contemporary production standards.
