About this product
The PERRIN Performance Ball Shift Knob is a heavyweight brushed stainless steel upgrade for the 2004-2021 Subaru WRX STI that improves shifter feel while sharpening up the look of your interior.
- Heavyweight solid stainless steel body — 347 g (0.8 lb), up to two times the weight of the OEM knob — for smoother, more precise shifts, especially with aftermarket short shifters
- 2.0-inch ball profile, precision machined and finished in raw brushed stainless steel
- Height adjustable by as much as 1 inch with the built-in adjustment screw; the lock bolt secures the knob without damaging shifter threads
- Multi-piece design with a billet aluminum lower section that fits precisely around the reverse lockout lever for a clean OEM+ appearance
- Includes shift boot adapter, O-ring, M12 set screw, velvet pouch, M6 hex key, warranty, instructions and stickers
- PERRIN part #PSP-INR-131-3
