Product Description

The Perrin PSP-INR-131-2 Brushed Stainless Barrel Shift Knob is a premium interior enhancement designed to elevate your manual transmission experience. Its heavyweight stainless steel construction - up to twice the weight of many OEM shift knobs - provides a smoother, more positive shift feel, especially when paired with short-throw shifters or performance driving setups. The brushed finish not only looks excellent but also offers long-lasting resistance to wear and corrosion.

Installation is straightforward on any manual car with a standard M12x1.25 thread, and the included shift boot adapter and hardware ensure a clean and secure fit. With adjustable height via a built-in set screw and a lower billet aluminum adapter designed around the reverse lockout, this shift knob is a popular choice for enthusiasts looking to improve both the tactile feel and interior styling of vehicles such as Subaru BRZ, Scion FR-S, Toyota 86, and other compatible manual transmissions.
