DEWHEL Aluminium 3-Speed Shift Knob for Jeep CJ 5/16"-24 Black, 2-1/8" Dia — Period-Correct 1941–1978

DEWHEL’s black aluminum round shift knob replaces worn factory knobs on vintage Willys and Jeep CJ manual shifters with a period-correct 3-speed pattern and 5/16"-24 UNF thread.

This compact, machined aluminum knob measures 2 1/8" in diameter and presents a classic 3-speed shift diagram on its face. It’s engineered to match original-equipment thread size common to Willys/Jeep CJ models from 1941 through most of 1978 and some early 1979 CJs, offering a robust, corrosion-resistant upgrade for restorations or driver-focused builds. Because shifter replacements and later-model parts sometimes use larger threads, verify your shifter’s thread pitch before purchasing to ensure fitment.

Will this knob fit my vintage Jeep CJ shifter?

If your vehicle retains the original or an OE-style shifter with a 5/16"-24 UNF thread, this DEWHEL knob will thread on securely and function like the factory piece. It’s specifically sized for older Willys and Jeep CJ models and replicates the simple round ball style popular on period vehicles.

• Thread specification: 5/16"-24 UNF — confirm with a gauge or measuring tool.
• Compatible with 1941–1978 Willys/Jeep CJ and some early 1979 CJ shifters.
• Does not fit later-model shifters with larger or different thread pitches.
• Ideal for restoring era-correct interior appearance.

How durable and comfortable is the aluminum construction?

The knob is CNC-machined from aluminum and finished in a matte black coating to resist rusting and everyday wear. At 2 1/8" diameter the round profile provides a solid grip for frequent shifting while remaining lightweight to avoid excess leverage or shifter strain.

• Material: machined aluminum for strength and low weight.
• Finish: black coating resists corrosion and complements classic interiors.
• Diameter: 2 1/8" — ergonomic for many hand sizes and manual applications.
• Shift pattern: engraved 3-speed diagram for clear, period-accurate identification.

What should I check before ordering to avoid fitment problems?

Don’t assume your current shifter has the original thread size — many replacement or modern shifters use different pitches. Measure the thread with a gauge or compare to the specified 5/16"-24 UNF standard, and inspect whether any adapters are required to mate the knob to your lever.

• Verify shifter thread: 5/16"-24 UNF required for direct fit.
• Look for thread wear or aftermarket sleeves that change diameter.
• Adapters or bushings may be needed for non-original shifters — check before purchase.
• Not compatible with larger or metric-threaded replacement shifters.

How does the DEWHEL knob affect interior appearance and function?

The minimalist round ball styling restores a classic look and provides straightforward function without bulk. It suits restoration projects aiming for authenticity as well as driver-focused builds that prioritize tactile feedback and durable materials over modern styling flourishes.

• Classic, period-correct round ball design for authentic appearance.
• Black finish blends with vintage interiors and hides light scuffs.
• Engraved 3-speed layout keeps gear positions easy to read.
• Lightweight aluminum avoids unnecessary shifter leverage while staying durable.

Who this is for: Enthusiasts restoring Willys and early Jeep CJ models, vintage-vehicle drivers who need a durable replacement knob, or anyone seeking a straightforward period-correct shift knob with a 5/16"-24 UNF thread. If you have a newer or nonstandard shifter, confirm thread size or consider an adapter rather than assuming direct compatibility.
