The SST340S are steel #45 front and rear CVD shafts specified for use on the TRAXXAS 1/18 LaTrax SST platform. Supplied as a matched pair, these shafts are intended as direct replacements for softer or degraded originals, offering a robust drivetrain option for small-scale RC vehicles.
Installation occurs at chassis level and the shafts are made to align with LaTrax SST drivetrain geometry, using the vehicle's existing retaining hardware. During fitment verify gearbox and suspension clearances and confirm correct front and rear identification; trimming is rarely necessary for the stated model.
From a setup and maintenance viewpoint, steel #45 provides improved torsional stiffness and enhanced wear resistance compared with more compliant materials. Reduced deflection under load helps deliver consistent torque transfer and predictable handling. For optimal drivetrain efficiency use matching drive cups and routinely service bearings to limit friction and binding.
Recommended for serious hobbyists seeking a durable, well-fitting aftermarket shaft that supports consistent driveline behaviour and straightforward chassis-level installation.
