Cobb Stage 2+ Drivetrain Package — Weighted Black Knob + Black Lockout — 2004-2021 Subaru STI 6MT
The Cobb Stage 2+ Drivetrain Package for the 2004-2021 Subaru STI 6-speed manual transmission adds a Reverse Lockout Pull Ring to the Stage 1+ components. This listing is the Weighted Black knob with Black lockout variant. The combination of shift knob color and lockout color is what distinguishes this specific listing from other Stage 2+ variants — all mechanical performance components are identical.

What’s Included and Why It Works
The Stage 1+ Drivetrain Package for the Subaru STI 6-speed manual transmission combines three components that address the three main sources of imprecision in the factory shifting feel. The Cobb short throw shifter replaces the factory shift lever with a double-adjustable unit that provides a 15% or 35% reduction in throw length at the two adjustment positions — the shift gates are shorter, the lever moves less far between each gate, and gear selection requires less arm movement. The front and rear shifter bushings replace the factory rubber bushings with tighter-tolerance units that eliminate the slop and vagueness in the shifter’s lateral motion — bushings that have degraded or that were never tight to begin with are a major contributor to the imprecise, rubbery feel that STI owners frequently want to address. The shift plate installs at the base of the shifter and provides the adjustable geometry that determines throw length, working together with the bushings to produce a shift action that is both shorter and more precise.
Shift Feel, Color Combination, and Installation
The Stage 2+ Drivetrain Package adds a Reverse Lockout Pull Ring to the Stage 1+ drivetrain components. The reverse lockout is a lift-to-unlock mechanism on the shift knob that must be lifted before the transmission will accept selection of reverse gear, preventing accidental reverse engagement during aggressive forward-gear shifting. The Cobb reverse lockout pull ring replaces the factory mechanism — or adds one where the factory transmission lacks a built-in reverse lockout — with a color-matched unit that complements the shift knob. The lockout mechanism engages the reverse gate protection while the pull ring provides the tactile feedback needed to disengage it intentionally. Every Cobb Drivetrain Package is defined by the specific color combination of its shift knob and, on Stage 2+ packages, its reverse lockout pull ring. The knob and lockout colors are the distinguishing factor between variants of the same package — all other components (shift plate, bushings, and where applicable the short throw shifter) are identical across color variants. The shift knob choices include standard threaded knobs and weighted knobs; the weighted knob uses additional mass to reduce the perceived effort of shifting and provide a more settled feel during rapid gear changes. The specific color combination in this listing is called out clearly in the product title and the Details section — select the combination that matches the interior color scheme of the build.

Why Choose Cobb Tuning
Cobb Tuning has been developing performance software and hardware for turbocharged enthusiast vehicles since 1999. Founded in Austin, Texas, Cobb built its reputation on the Accessport and expanded into a full catalog of hardware engineered to complement it. Every OTS map is developed in-house on real vehicles, and every hardware product is validated as part of a complete system — not sourced and sold in isolation. That integrated approach is why Cobb produces consistent, reliable results across the builds we see every day.
The RallySport Take
The Cobb Stage 2+ Drivetrain Package for the STI 6MT is the complete drivetrain upgrade — every mechanical shortcut of the factory shifting experience addressed, plus the reverse lockout that prevents accidental reverse engagement during aggressive driving. The Black knob and Black lockout pull ring are the color-defining combination in this listing. All other Stage 2+ packages for the STI 6MT use the same short throw shifter, the same bushing kit, and the same lockout mechanism — the distinction is purely the knob and lockout colors chosen to match the interior.
