Stock plastic gear knobs feel like 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're working through low range on a rock shelf or cruising a highway on-ramp.
The bundled 5-inch extension raises the throw height to a more natural hand position, so your wrist stays comfortable on longer drives. Both pieces come in Black, Silver, Gold, Red, Pink, Purple and Green, so you can run a matched pair or contrast the knob and extension.
Fitment is straightforward on suited Toyota manual transmissions. The kit includes a thread adaptor and only fits M12 × 1.25 shifters. Check your thread pitch before you order.
Built for the driver's seat.
7075 BILLET ALUMINIUM
Machined from 7075-grade aluminium, one of the strongest alloys used in CNC components, so it holds up to real-world use.
ETCHED GRIP PATTERN
Motorsport-inspired texture is cut directly into the surface, not applied, so it stays grippy and looks sharp for years.
49 COLOUR COMBINATIONS
Seven anodised colours on both the knob and the extension give you a matched or contrasting look for your interior.
