This adjustable main shaft serves as a hop-up replacement for the TAMIYA CC01 scale chassis, combining a 6061-T6 aluminium outer body with a hardened steel swing cross head to keep strength where you need it while trimming unsprung mass for crawling lines.
The construction pairs an aluminium 6061-T6 sleeve with hardened steel #45 cross head swing shafts, retaining the factory cross-pin interface while lowering rotating weight. The universal cross head expands steering travel, which is useful on tight obstacles where extra articulation prevents tyre lift.
The unit measures 126mm in total length and is intended for short chassis configurations with a 240mm wheelbase. Fitting requires basic CC-01 drivetrain disassembly to swap the factory main shaft for this adjustable unit, suitable for hobby RC crawling applications.
The package includes the small reassembly hardware referenced in the original product notes and is aimed at improving steering geometry and cutting drivetrain mass rather than modifying gearbox internals.
Use this shaft to reduce rotating mass while gaining additional steering angle on CC-01 short-wheelbase crawlers, with straightforward installation for field tuning.
