DETAILS

These shift knobs extenders are a necessity for comfortable and ergonomic shifting. The added height allows for a shorter reach from the steering wheel to the shift knob and also allows for more leverage when shifting. These extenders perform even better with an installed short shifter!

Each Extender is CNC machined, polished, and anodized for a perfect, scratch-resistant finish.

Confirmed fitment for 6-Speed Subaru’s (includes proper clearance for factory reverse lockout).
