2" Shift Knob Extender - 5-Speed WRX/STI Fitment

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 5-Speed Subaru’s (includes a built-in boot retainer).

Wish I came here first

I have tried numerous shift knobs and multiple height variations. Wish I would have tried this extension first, would have saved me a lot of money in knobs. I have the factory short throw shifter, with Group N rear mount and Kartboy front mount. I have paired the assembly with the optional factory delrin knob and 2" extension and wow. You get the crisp shifts still while have that bit more leverage. Something often overlooked, but I am 6'3" and I need to sit further back. You need that extra reach on the shifter but you don't want too much extra that makes it feel like shifting mush. This 2" extension bridges that gap beautifully.

Must buy!!

I've had the full Billetworkz short throw shifter kit installed in my car for about three months. This extender is an absolute game changer! I wish I would have bought it right away... Looks awesome and makes my shifts feel smooth as butter! 100% would recommend!

Quality product!

Perfect fit and finish, looks like it came factory in my 2021 wrx. Must have option if you’re tired of hitting drinks in cup holders while shifting. Billetworkz never disappoints!
