4-Inch Shift Knob Extender – Subaru WRX/STI 6-Speed

Upgrade your driving experience with the Billetworkz 4-inch Shift Knob Extender — designed for more comfortable, ergonomic shifting. By raising the height of your shift knob, the extender reduces the reach from the steering wheel and provides extra leverage for smoother, quicker gear changes. Pair it with a short shifter for even greater performance gains.

Each extender is CNC-machined from high-quality aluminum, then polished and anodized for a durable, scratch-resistant finish that looks as good as it feels.

• Precision fitment for 6-speed Subaru models (i.e. WRX, STI, BRZ (excluding 22+), Crosstrek, Forester, Legacy, Outback)
• Designed with proper clearance for the factory reverse lockout
• Easy install — no modifications required

Take control of every shift with a part that combines style, comfort, and performance.
