A shift worth making.
Stock plastic gear knobs are an afterthought. The Circuit is the opposite. CNC machined from 7075 billet aluminium and finished with a precision-etched grip pattern, it gives you positive, confident feedback whether you are working through low range on a rock shelf or cruising the highway on-ramp.
The bundled 5-inch extension raises the throw height to a more natural hand position, reducing wrist fatigue on longer drives. Both pieces are available in Black, Silver, Gold, Red, Pink, Purple and Green, so you can run a matched pair or contrast the knob and extension independently.
Fitment is straightforward on suited Toyota manual transmissions. The kit includes a thread adaptor and is compatible only with M12 × 1.25 shifters. Confirm your thread pitch before ordering.
Built for the driver's seat.
7075 BILLET ALUMINIUM
Machined from 7075-grade aluminium, one of the strongest alloys used in CNC components, for durability that handles real-world use.
ETCHED GRIP PATTERN
Motorsport-inspired texture is cut directly into the surface, not applied, so it stays grippy and looks sharp after years of use.
49 COLOUR COMBINATIONS
Seven anodised colours on both the knob and the extension give you a matched or contrasted look to suit any interior build.
