Total add-ons:
Upgrade your Subaru STI with a billet aluminum reverse lockout. Anodized, rattle-free, and a direct 6-speed replacement for smoother, cleaner shifts.
The Billetworkz STI Reverse Lockout is a premium, one-piece replacement for your factory reverse lockout and boot retainer. Designed for precision and longevity, each lockout is CNC-machined from high-grade aluminum and finished with a scratch-resistant anodized coating that holds up to daily driving.
Unlike the OEM design, our lockout features dual internal O-rings that reduce vibration and prevent unwanted rattling. A stainless steel set screw is included for secure installation—no roll pin required. The result? A smoother, crisper shift experience and a sleek interior upgrade that pairs perfectly with any Billetworkz shift knob.
If you're looking to refresh worn OEM components, eliminate rattle, or elevate your interior, this is a direct-fit upgrade designed specifically for Subaru enthusiasts.
Note: Lubricate O-rings before installation for proper function.
Fitment: Subaru STI 2004–2021 (6-Speed) and some 6-Speed Legacy’s. Please contact us to confirm fitment.

Dominick Gee Looks great but sticks even after lubing both o-rings. Hoping it gets better with wear. The shift boot collar is a bit small as well.

R Williams My stock reverse lockout was starting to rattle at higher RPMs. I already had the hybrid know from Billetworkz so this was an easy choice. Simple install in about 10-15 minutes thanks to the Billetworkz YouTube tutorial. My only complaint is that it’s not available in brushed aluminum to match my knob, but the red still pops.

Jason Tarasyuk Very nice product, I added a little grease to my o rings inside as it was dragging with the kart boy short shifter. I got this so I can run a 450g shift knob without any vibrational noises and it works very well. Satisfied with my purchase!

Matt Gordon The reverse lockout was super easy to install, just watch the step by step instruction video and it’s a piece of cake. Only thing I’d say is even with lubing the o-rings inside the lockout, it still seems to stick a little. Hoping it gets better the more it’s used. But other than that, definitely looks a lot better than the factory one.

Brandon Bridwell This product was easy to install. Looks amazing intalled with a billetworks weighted shift knob. I definitely recommend this product.

Ry P I installed one on a stock OE short shifter, then move it to a Kartboy short shifter, the quality itself is very good- only minor gripes:
1)- on a stock style shifter you will experience sticking while pulling up- the OE shift arm has a step where the threads for the shift knob engage, and it will cause an occasional hangup- it has to do with the upper o-ring being slightly too high on the lockout.
This does not happen with a Kartboy- it's smooth. Use some sort of silicone grease (disc brake grease is great)
2)- I wish the piece came with the allen wrench- it's a itty-bitty metric size not commonly used on cars, couldn't find at the store either. PITA.
3)- the upper lip that is supposed to hold the shift boot down is slightly undersized, so the shift boot may want to slip upward, hitting where your fingers pull up.
The solution to this is prior to installing the console, pull the shift boot inside out, and zip-tie the top of the shift boot into the groove on the lockout it's supposed to stay in. Then install the console. It will never slip up again.
