COBB Tuning Subaru 5-Speed Weighted COBB Knob

Cobb 5-Speed Weighted Shift Knob — Black — Subaru 5MT

The Cobb 5-Speed Weighted Shift Knob in Black is a direct-thread replacement for the factory 5MT shift knob on Subaru 5-speed manual applications. The 825g weighted construction provides settled inertia between gear changes on the GD and GR WRX 5MT platform.

825g Weighted Construction for the Subaru 5MT Platform

The Cobb Weighted Shift Knob uses additional mass — approximately 825 grams — compared to a standard factory or Delrin knob. The weight is distributed through a machined aluminum core with a Delrin outer shell. The extra mass provides two practical benefits: first, it reduces the perceived effort of each gear change by providing inertia that carries the lever through the shift gate; second, it keeps the lever settled between gear changes rather than vibrating or drifting with engine and road inputs. On a turbocharged Subaru with the engine’s characteristic vibrations, a weighted knob feels noticeably more planted and intentional than a lightweight one.

Standard Height and 5MT Thread Compatibility

The Cobb Weighted Knob is available in short and tall configurations. The short version sits at a similar height to the factory knob — the mass is concentrated lower on the lever. The tall version raises the knob position on the shaft, changing the shift lever mechanics: a longer moment arm requires slightly less force to move the lever, and the different hand position changes the ergonomics of the shift motion. Both configurations deliver the same 825g weight. Thread engagement is correct for Subaru and compatible manual transmission applications — the knob threads directly onto the factory or Cobb short throw shifter shaft without adapters.

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 Weighted Knob in Black for the Subaru 5MT brings the same shifted-inertia improvement to the 5-speed platform. Combined with the Cobb bushing kit and shift plate, the weighted knob completes the Stage 1+ drivetrain upgrade for the GD and GR WRX.
