Perrin Barrel Shift Knob 2004-2021 STI

The PERRIN shift knob features a heavyweight, solid steel body that is up to two times the weight of the OEM knob. Heavyweight knobs are great for smoother shifts, especially with aftermarket short shifters.

The PERRIN Shift Knob features a multi-piece design for precise fitment and easy installation. The main body is CNC-machined from heavyweight stainless steel with a durable raw brushed finish. A billet aluminum lower section fits tightly around the reverse lockout lever for a clean, secure setup.

The PERRIN Shift Knobs height can be adjusted by as much as 1 inch with the built-in adjustment screw. Once the height is set, tighten the lock bolt and your knob will never loosen on its own. Best of all, our super locking mechanism will not harm the threads of your shifter!

The PERRIN Shift Knob Adapter eliminates shifter rattles caused by aggressive driving and high mileage. Designed to seal around the reverse lockout lever, the PERRIN adapter eliminates shifter rattles while allowing for smooth, easy reverse lockout operation.

The PERRIN Shift Knob adds weight and stability to your gear shifts, helping them feel smoother and more solid. It’s built from strong stainless steel and aluminum, fits snugly, and won’t rattle or loosen over time.
