Upgrade your driving experience, and customize your own Billetworkz 4-inch Shift Knob Extender for Focus ST, Focus RS, and Fiesta ST models. By raising the height of your shift knob, the extender reduces the reach from the steering wheel and gives you extra leverage for smoother, more ergonomic gear changes. Pair it with a short shifter for even greater performance and control.
Each extender is CNC-machined from high-quality aluminum, then polished and anodized for a durable, scratch-resistant finish that looks as good as it feels.
- Precision fitment for Focus ST, Focus RS, and Fiesta ST
- Designed with proper clearance for the factory reverse lockout
- Quick, tool-free installation
Enjoy a more comfortable, performance-focused drive with a simple upgrade that enhances both feel and style.

kyle Bought this on the recommendation of email exchange with a BW employee.
At the time I didn’t want to exchange the “sti” version I bought that fit well just got in the way of the reverse lockout a little.
I was enjoying it well enough and wasn’t going to ask BW to hassle with it even though they offered.
Fast forward a few weeks later and I bought the recommended rs/st version.
Works perfectly with the lockout now! No dragging and it still looks great with the BW “clown nose” red ball shifter .
Top notch service (even when the customer is stubborn) and perfect quality product.

k. Was looking for an extension for my GR C shifter as the stock was a bit low for my personal tastes (6'2" and 290 ish , gravitational mass made it uncomfortable some days) , looked around and read reviews figured out this would work for me. Used the provided nut to keep the reverse lockout working . Looks great , improves the feel a lot and when I am lazy? It acts as a impromptu arm rest !

Trey Adkins Just want to start out by saying that billetworkz is a great company to work with, they genuinely care. Next this extender is incredible it looks great perfect color for me and paired with my shift knob I think it’s a great combo. The height of the extender makes shifting a breeze and puts your hand in a very comfortable position. I will definitely do business with billetworkz again.

ZR I have the Billetworkz short throw shifter on as well, but I won’t go into details on the shifter until I make a review on that.
I originally had on the 2 inch extender on and that felt pretty good. However, I thought what the hell, there’s a sale on accessories and I’ll try the 4 inch. It felt pretty big and the hand placement took some getting used to, but I felt like the extra extra long handle has made my transmission shift just a liiiiiiittle better over the 2 inch (transmission issues from the start when I got it). I feel like I can shift better from 4th to 5th with the 4 inch on than the 2 inch and WAY better over no extender at all. It still makes me giggle from time-to-time when I see its glory in the sun and how ridiculous it probably looks, but it definitely has wow factor for sure.
I will say you should have a small crescent wrench in your glovebox with some painter’s tape on there to tighten it down just a little more when you need to. Maybe I wasn’t tightening it on tight enough, but I felt like it was coming loose a little bit. I got it to wear it wasn’t wiggling loose. No big deal.
In summary: Great given you have the short throw shifter on.

ZR When I first got it and put it on it made me laugh every time I got in the car because it just looked so funny. I felt like a trucker with those huge shifters. But when I started to drive… my transmission has had problems (Scion FR-S, first gen BRZ problems), but I felt like a little more leverage helped just to get the damn thing into gear better. It was really enjoyable to drive with the stock shifter. It just felt good. I don’t really know how to describe it. Not sure how the 4 inch feels like, but to me the 2 inch has the correct height. (But if I had a friend with the 4 inch, I would try it immediately for the laughs.) The car is always fun to drive, but it freshened her up a bit. I wish I would have bought this sooner. But now I have on the Billetworkz short throw shifter… but you’ll have to wait for that review.
Overall: It looks great, makes the shifts feel good (maybe objectively, maybe subjectively), and it still makes me giggle when I “wake up” and go “oh yeah, this thing looks ridiculous and it’s fantastic”. Definitely worth the buy. It earns 5 stars with ease.
(Note: the picture is with the stock shifter. In my short shifter review, whenever that will be, I’ll post the picture with the red lockout on. Spoiler alert: it’s pretty damn sexy)
