Mishimoto Weighted Shift Knob — Universal White Steel, 360 g Mass & Polished Finish

The Mishimoto MMSK-WH is a universal white steel weighted shift knob that adds 12.8 oz (360 g) of mass for smoother, more deliberate gear shifts while upgrading interior style.

If you want a simple bolt-on part that changes how your manual transmission feels and looks, the MMSK-WH delivers a heavier, well-balanced shift lever finished in polished white. Machined from premium steel and finished with Mishimoto's signature "M" logo, this knob is built to resist wear and provide consistent feel across daily driving and spirited runs. Three included thread pitch adapters make it compatible with a broad range of manual vehicles, though cars with pull-up reverse lockouts may require a different solution.

How does the extra weight improve shifting?

Adding mass at the end of the shifter reduces the effort needed to slot gears and dampens small vibrations, which helps gears engage more smoothly. The inertia from the 360 g weight lets the lever settle into position quickly, reducing missed shifts and making row-through motions feel more refined.

• 12.8 oz (360 g) steel core for stable gear engagement
• Mass dampens high-frequency shifter vibrations
• Improves momentum when moving between gears

Will it fit my car’s shifter?

The MMSK-WH is built for broad compatibility and includes three thread pitch adapters—M8 x 1.25, M10 x 1.5, and M12 x 1.25—so it fits most manual transmission vehicles. Double-check your factory thread pitch and whether your vehicle uses a pull-up reverse lockout, since that style can prevent direct installation.

• Includes M8, M10, and M12 adapters for versatile fitment
• Not compatible with some pull-up reverse lockout mechanisms
• Consult vehicle manual or measure thread pitch before installation

How durable and comfortable is the finish?

The knob’s polished white steel finish resists scuffs and retains a clean look with normal use, while the contoured shape makes it comfortable during long drives or aggressive shifting. Mishimoto machines the surface to high tolerances and stamps the "M" logo for an OEM-grade appearance.

• Polished white steel resists wear and maintains sheen
• Ergonomic contour reduces hand fatigue during shifts
• Mishimoto "M" logo adds a refined, factory-style accent

What’s involved in installation?

Installation is straightforward for anyone familiar with shifter hardware: remove your factory knob, select the matching adapter, thread the Mishimoto knob on, and tighten securely. Some vehicles may require minor adjustments or retention hardware; always follow your vehicle’s instructions for reassembly and torque settings.

• Simple screw-on installation with supplied adapters
• May require threadlocker or set screw depending on shifter design
• Refer to vehicle manual for reverse lockout and torque guidance

Who is this for? The Mishimoto MMSK-WH suits drivers who want a tangible improvement in shift feel and a clean, sporty interior detail. It’s ideal for enthusiasts who use their car on the street and the occasional track day, DIYers who prefer a quick upgrade, and anyone seeking a durable, ergonomic replacement for a worn factory knob. If your vehicle uses a pull-up reverse lockout or an uncommon thread pitch, verify compatibility before purchase to ensure a trouble-free install.
