What's the best material for a shift knob?
Share
In the realm of automotive customization, every detail counts, down to the gearshift knob. The material from which a shift knob is crafted not only impacts its appearance but also its feel, durability, and even weight. Let's dive into the world of shift knob materials and uncover the unique advantages and drawbacks of each.
- Stainless Steel:
Advantages: Stainless steel shift knobs are prized for their durability and resistance to corrosion. They offer a solid, substantial feel in the hand and can withstand the rigors of daily use without showing signs of wear. For fans of weighted shift knobs, stainless steel is denser than most other materials used in shift knobs, lending for a heavy knob in a small package. Stainless steel is also a relatively cheap metal in bulk, making stainless steel knobs rather affordable compared to other metal options.
Disadvantages: Ouch! Stainless steel shift knobs can become uncomfortably hot or cold to the touch in extreme weather conditions, especially under the baking sun in warmer climates such as Florida or California. Additionally, they tend to be heavier than other materials, which may not be to everyone's preference. Certain stainless steel knobs are priced close to their aluminum counterparts, which ruins the value argument behind stainless steel.
- Aluminum:
Advantages: Aluminum shift knobs strike a balance between durability and weight. They are lightweight yet sturdy, providing a satisfying shifting experience without adding too much bulk to the gear lever. Many iconic metal shift knobs have been produced in aluminum, in part due to its attractive finish when machined. Aluminum is easy to work with, resulting in manufacturing savings that can be passed on to the consumer (but isn’t always…)
Disadvantages: While aluminum is relatively resistant to temperature changes, it may not offer the same level of insulation as other materials such as Delrin. Though some may appreciate its light weight, those looking for a heavier weighted shift knob will find this insufficiently dense. If not properly surface treated, a raw aluminum finish will start to oxidize into a fine white powder that gets everywhere—make sure your aluminum shift knobs are anodized, even with a clear anodized finish such as that on the CHF Engineering ‘Teardrop’ Aluminum Shift Knob.

- Titanium:
Advantages: Titanium shift knobs are prized for their strength-to-weight ratio, making them incredibly lightweight yet exceptionally durable. They offer a unique aesthetic appeal with a distinct metallic sheen that is easily identified against other metals. No other metal carries quite the exotic associations as titanium does: typically featured in high-end goods such as expensive bicycles and crazy racecars, or on the cutting edge of mankind such as fighter jets and spacecraft, titanium is indisputably a sexy metal.
Disadvantages: Titanium shift knobs can be expensive due to the cost of the material and the manufacturing process involved, typically costing the most compared to shift knobs of other materials. Additionally, they may lack the warmth and tactile feel of materials like wood or leather, but can be more resistant to temperature changes compared to other metals such as aluminum and stainless steel. Due to its cost, titanium knobs tend to be rare and therefore are offered in limited designs.
- Delrin:
Advantages: Delrin, a type of acetal resin, is known for its high strength, stiffness, and low friction properties. Delrin shift knobs offer a smooth, comfortable grip and are less prone to temperature extremes compared to metal counterparts. If you’re worried about burning your hand on your shift knob on a hot summer day, this is the material choice for you! Its low cost lends to affordably-priced knobs if manufactured entirely out of Delrin; this isn’t always the case. Delrin is also available in a wide variety of colors, and due to its polymer nature, can make those colors pop in a way that no other material can.
Disadvantages: While durable, Delrin shift knobs may not have the same aesthetic appeal as metal or natural materials like wood or leather. They can also be prone to scratching and may require periodic care to keep them looking their best. A fully Delrin construction knob would be very light, sometimes too light for people’s tastes.
Sidenote: A weighted Delrin knob attempts to bridge the divide between those who enjoy Delrin’s unique silky smooth finish while wanting a heavier feel. This takes advantage of the density of metal while allowing the creative shapes, colors, and smooth finish that Delrin allows.
- Leather:
Advantages: Leather shift knobs exude a sense of luxury and sophistication, adding a touch of elegance to any interior. They offer a comfortable grip and are less affected by temperature changes compared to metal or plastic.
Disadvantages: Despite their luxurious appearance, leather shift knobs may require more care and maintenance to keep them looking pristine. They can also be susceptible to wear and tear over time, especially in high-use areas. For those looking to stand out, a leather knob can blend into the background of OEM factory knobs, many of which are also leather wrapped.
- Wood:
Advantages: Wood shift knobs offer a timeless aesthetic that complements both classic and modern interiors. They provide a warm, natural feel in the hand and are less affected by temperature changes compared to metal.
Disadvantages: While visually appealing, wood shift knobs may be more prone to scratching and require periodic polishing to maintain their luster. They can also be more expensive than other materials, depending on the type of wood used. Due to its imperfect material properties, wood shift knobs are rarely seen and as such come in limited designs.
The choice of material for a shift knob is a highly personal one, influenced by factors such as durability, aesthetics, weight, and cost. Whether you prefer the sleek look of stainless steel, the lightweight feel of aluminum, or the timeless elegance of wood, there's a material out there to suit every taste and driving style. At the end of the day, it doesn’t matter what shift knob you have as long as we’re all still rowing through our own gears.
