DEWHEL Aluminum 3‑Speed Shift Knob for Jeep CJ 5/16"‑24 Thread — Black 2.125" Ball, Machined Engraved Pattern

The DEWHEL Aluminum 3-Speed round shift knob is a classic black, 2 1/8" diameter replacement made to fit 5/16"-24 UNF threads on 1941–1978 Willys/Jeep CJ transmissions (also fits some early 1979 CJs).

If you’re restoring a vintage Willys or Jeep CJ and need an authentic-looking shifter knob that threads directly onto older factory-style levers, this DEWHEL aluminum knob gives you a durable, period-correct option. It presents a clean black finish and an engraved 3-speed pattern, sized to match the original OE 5/16"-24 thread common to T90, T14, T15 and T150 transmissions used in 1941–1978 models. Before ordering, confirm your shifter’s thread to avoid mismatches—many replacement shifters and later models use different, larger threads.

Will this knob physically fit my Jeep’s shifter?

Yes if your vehicle has the OE-style 5/16"-24 UNF thread used on many Willys/Jeep CJ models from 1941 through 1978 (and some early 1979 CJs). It’s designed for direct screw-on installation to those factory threads.

• Thread size: 5/16"-24 UNF — confirm with a thread gauge or compare to original knob.
• Diameter: 2 1/8" round ball for comfortable hand placement.
• Compatible transmissions: common on T90, T14, T15, T150 gear levers.

How does the DEWHEL aluminum knob hold up to daily use?

The knob’s lightweight aluminum construction resists cracking and warping while offering solid tactile feedback for shifting. Its black finish and machined pattern stay readable with normal use and cleaning, and the metal core provides long-term durability versus plastic alternatives.

• Material: machined aluminum for strength and reduced vibration.
• Finish: black coating that resists wear from regular handling.
• Pattern: engraved 3-speed markings maintain visibility over time.

What should I check before buying to avoid a threading mismatch?

Don’t assume your current shifter still uses the original thread size—many replacement shifters and later-model vehicles use larger threads. Measure or inspect the thread pitch and diameter, or remove the old knob and compare it directly to the 5/16"-24 specification.

• Measure thread diameter and pitch with a caliper or thread gauge.
• Compare to OE 5/16"-24 specs listed on this product before purchase.
• If unsure, remove existing knob and bring to a parts store or consult a mechanic.

How easy is installation and what tools are needed?

Installation is straightforward for most users: the knob screws onto the existing threaded shifter shaft. No special tools are required for most installs, though a small wrench or thread locker can secure it if the previous knob was tight or threaded with an adapter.

• Method: screw-on installation to a matching 5/16"-24 threaded shaft.
• Tools: typically hand-tighten; optional small wrench or thread locker for extra security.
• Tip: clean threads and inspect for adapters before attaching the new knob.

Who this is for: This DEWHEL knob is ideal for owners restoring or preserving vintage Willys and Jeep CJ vehicles who need an authentic-size, durable replacement for original 3-speed shifters. It’s also a practical upgrade for drivers seeking a metal, period-style knob over modern plastic alternatives—provided your shifter retains the original 5/16"-24 threading. If your Jeep uses a later or aftermarket shifter with a larger thread, measure first or consider a compatible adapter to ensure a proper fit.
