Product Description

The Mishimoto MMSK-SL is the polished silver variant of Mishimoto's standard weighted shift knob - a straightforward, well-executed upgrade over the factory unit that improves shift feel without requiring any permanent modifications. Constructed from steel and weighing in at 12.8 oz (360 grams), the MMSK-SL delivers noticeably more inertia per shift than the light plastic or hollow-metal knobs found on most OEM shifters. That added weight helps the knob glide through gear detents more easily, making shifts feel more deliberate and less effortful - whether you're daily driving, autocrossing, or running mountain roads.

The polished silver finish pairs with Mishimoto's signature "M" logo at the top, offering a clean, refined look that complements both factory and upgraded interiors without looking aftermarket-loud. The cylindrical / tapered shape is ergonomic and fits naturally in the hand during both short and extended drives. Installation takes under five minutes on most vehicles - simply press the correct thread adapter (M8x1.25, M10x1.5, or M12x1.25) into the base, then thread onto the shifter.

The MMSK-SL covers virtually all manual transmission platforms through its three included thread inserts and is the silver counterpart to the MMSK-BK (black) and MMSK-XL-SL (XL silver) in the Mishimoto shift knob lineup. For drivers who want the larger, heavier XL version in silver, that is the MMSK-XL-SL. Backed by Mishimoto's Lifetime Warranty.
