Cobb Subaru 5-Speed COBB Knob - Race Red - 2002-2014 Subaru WRX / 2004-2008 Forester / 2005-2009 Outback / Legacy

The Shift Knob Your Hand Deserves

The Cobb Cobb Subaru 5-Speed COBB Knob - Race Red - 2002-2014 Subaru WRX / 2004-2008 Forester / 2005-2009 Outback / Legacy is a Delrin shift knob designed as a direct replacement for the factory unit on 2008-2021 Subaru WRX STI . Delrin is a precision-machined engineering plastic with a surface hardness and density that gives it a weighted, solid feel without the full mass penalty of an aluminum knob — it's comfortable in both cold and hot conditions and doesn't transfer heat or cold the way bare aluminum does. This listing is the Red variant.

Thread-On Replacement — Factory Location, Better Feel

The Cobb shift knob threads directly onto the factory shifter shaft on the GR/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 Delrin 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 GR/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 GR/VA STI doesn't do the car justice. The Cobb Delrin 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.

About Cobb Tuning

Cobb Tuning has been developing performance parts and tuning solutions for Subaru vehicles since 1999. Based in Austin, Texas, Cobb built their reputation on the Accessport — the most widely used Subaru ECU tuning device on the market — and expanded that into a full ecosystem of intake, exhaust, drivetrain, and engine bay accessories engineered specifically for the platforms they support. 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.
