Traxxas Complete Low Range Crawl Gearing with Titan 87T Motor RC Transmission - 9791R

The Traxxas TRX9791R is a complete transmission assembly with low range (crawl) gearing for the Traxxas TRX-4, and it includes the Titan 87T motor as part of the unit. Designed specifically for rock crawling and technical off-road driving, this transmission delivers the deep gear reduction needed to maintain control at ultra-low speeds over challenging terrain. It's a direct-fit assembly for compatible TRX-4 models, making it a straightforward swap whether you're replacing a worn transmission or converting to low range crawl gearing from a standard setup.

Key Features

• Complete transmission assembly with low range (crawl) gearing pre-installed — no separate gearing configuration required
• Includes the Titan 87T motor, which is matched to the crawl gearing ratio for low-speed torque and controlled trail performance
• Direct-fit design for compatible TRX-4 models (97044-1, 97054-1, 97064-1, 97074-1) — drops in without modification
• Low range gearing is optimised for rock crawling, providing the slow, deliberate wheel speed needed for technical obstacles
• OEM Traxxas part (style code TRX9791R) ensures correct fitment and compatibility with the TRX-4 drivetrain
