Cobb 6-Speed Shift Knob - Black w/Race Red Collar (Non-Weighted) - 2004-2021 Subaru STI / 2015-2026 WRX / 2006-2012 Legacy

The Shift Knob Your Hand Deserves

The Cobb Cobb 6-Speed Shift Knob - Black w/Race Red Collar (Non-Weighted) - 2004-2021 Subaru STI / 2015-2026 WRX / 2006-2012 Legacy is a weighted aluminum shift knob designed as a direct replacement for the factory unit on 2015-2021 Subaru WRX STI . The additional mass of the weighted design changes the feel of every gear change — a heavier knob naturally resists being rushed, encouraging more deliberate, positive shifts through the gate. This listing is the Black variant.

Thread-On Replacement — Factory Location, Better Feel

The Cobb shift knob threads directly onto the factory shifter shaft on the VA STI — no adapters, no modifications to the shifter. It replaces the factory knob at the same height and position, so it integrates naturally with the rest of the interior. The weighted aluminum construction is sized and weighted to complement the Cobb Short Shifter, though it pairs equally well with the factory shifter.

Part of the Cobb Drivetrain Ecosystem

The Cobb shift knob is part of the broader Cobb drivetrain lineup for the VA STI — it's available individually or as part of the Cobb Stage 1+ Drivetrain Package with the Cobb Short Shifter and bushing kit. Running the full package gives you a complete, matched shifter system from one manufacturer rather than mixing individual components from different sources.

Straight From Subispeed

The shift knob is one of the most-touched parts on a manual transmission car, and the factory plastic unit on the VA STI doesn't do the car justice. The Cobb weighted knob is a simple swap that changes the feel of every drive — and it's the right starting point if you're building toward the full Cobb drivetrain package. Small purchase, big daily driver impact.

Every Cobb product is developed in-house and validated on their own test vehicles before it reaches customers. Subispeed carries the full Cobb catalog because their engineering standards and platform-specific development process consistently produce parts that work exactly as advertised.
