Product Description

The Mishimoto MMSK-BK is the polished black variant of Mishimoto's standard weighted shift knob - the most popular entry point in the Mishimoto shift knob lineup and a direct, no-modification upgrade over any factory plastic or hollow-metal shifter. Constructed from steel and weighing in at 12.8 oz (360 grams), the MMSK-BK adds meaningful inertia to every gear change, helping the knob glide through detents with less effort and producing a more planted, deliberate feel in hand. The difference is immediately noticeable on the first shift: the knob moves with purpose rather than requiring a flick of the wrist.

The polished black finish is clean and understated, working naturally with both stock and modified interiors. Mishimoto's signature "M" logo is centered on the top face, adding a recognizable brand element without being visually heavy. Installation takes under five minutes on the vast majority of manual transmission vehicles - press the correct thread adapter (M8x1.25, M10x1.5, or M12x1.25) into the base, thread the knob onto the shifter, and torque to hand-tight. No tools required.

The MMSK-BK is the standard-size, smooth-finish version in black. For drivers who want more grip texture, the MMSK-XLK-BK adds a full knurled surface and XL sizing. For a heavier, taller option without knurling, the MMSK-XL-BK provides nearly two full pounds in the same black finish. All variants use the same three thread inserts and are covered by Mishimoto's Lifetime Warranty.
