XV-02/TT-02 F Direct Coupling Set 39T

The XV-02/TT-02 F Direct Cpl 39T is a Hop-Up Option set for RC drivetrain tuning, built to give XV-02 and TT-02 chassis a more direct front drive feel on low-grip surfaces. By replacing front differential action with a direct coupling, this setup channels power to the front wheels in a more immediate way, which can sharpen launch response when traction is limited. The assembly shown in the set uses a 39-tooth gear together with outdrives, bearings, circlips, pins and screws, creating a dedicated front-end drivetrain unit rather than a general-purpose hardware pack. That focused layout makes it a targeted tuning change for drivers adjusting handling balance at the axle level. The effect under braking is equally important: with reduced differential effect at the front, the chassis can stay more composed as speed comes off and the car turns into a corner on dusty, loose or otherwise slippery tracks. This kind of tuning suits track sessions where surface grip changes through the day or where a standard differential setup gives away too much drive at corner exit. Installed in a compatible XV-02 or TT-02 chassis, the set supports a more locked-in front response for acceleration zones, braking points and repeated lap tuning on technical layouts.
