The XPT3 LCG Transmission from Reefs RC is a purpose-built, ultra-compact drivetrain upgrade engineered for competitive 1/10 crawlers. Weighing in at just 75 grams, the XPT3 delivers a true low-CG advantage without sacrificing strength or reliability.
Designed with a machined aluminum case, hardened steel gears, and titanium output shafts, this transmission is built to take abuse while maintaining smooth, precise power delivery. The forward motor mounting improves balance and packaging, while 48-pitch gearing and an easy-set gear mesh with protective cover keep performance consistent even in harsh trail conditions.
Whether you’re running straight axles or portals, the XPT3 offers flexible gearing options to dial in the perfect final drive for your setup—making it a serious upgrade for high-end crawler builds.
