In the pits, speed is everything—even during routine maintenance. Fumbling for a screwdriver or a socket just to check your air filter or adjust a carburetor can waste valuable seconds. The Longacre 32754 Replacement Thumb Knob is the professional solution for quick, tool-free access to your engine's air cleaner assembly.
Designed as a direct replacement part for the Longacre Air Cleaner Stud Kit, this knob features a 1/4"-20 internal thread. It is CNC-machined from lightweight billet aluminum and finished in a vibrant Red Anodized coating. The oversized, knurled outer diameter provides a superior grip, allowing mechanics to securely tighten or remove the air cleaner lid by hand, even while wearing racing gloves or dealing with oily fingers.
Key Features
-
Tool-Free Operation: Eliminates the need for a screwdriver or wrench to remove the air cleaner lid, making filter inspections and carburetor adjustments significantly faster between heat races.
-
Billet Aluminum Construction: Machined from high-quality aluminum for a perfect balance of strength and weight, ensuring it won't vibrate loose or strip like cheap plastic alternatives.
-
High-Grip Knurled Texture: The deep diamond-knurl pattern ensures a non-slip grip in all conditions, providing maximum torque for a hand-tight seal that stays put under high-frequency engine vibrations.
-
Vibrant Red Anodized Finish: The durable anodized coating doesn't just look great; it protects the aluminum from corrosion and makes the knob easy to locate in a dark engine bay.
