A premium upgrade for your Subaru interior, CNC-machined from solid Grade 5 Titanium and finished in a clean, brushed texture for a refined OEM-plus look.
The Billetworkz STI Reverse Lockout – Titanium Brushed is a high-end, one-piece replacement for your OEM reverse lockout and boot retainer. Crafted from Grade 5 Titanium, each piece is precision CNC-machined to deliver exceptional strength, corrosion resistance, and a premium feel every time you shift.
Our one-piece design features an integrated boot retainer for a cleaner profile and improved durability. Internally, dual O-rings reduce vibration and eliminate rattles, while a stainless steel set screw replaces the OEM roll pin for easier installation and long-term reliability.
The brushed finish gives this lockout a modern, understated look—perfect for drivers who prefer a subtle, ultra-premium aesthetic.
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.

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.

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!

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.

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

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.
