The JAZRIDER JR-TT2B03-LB rear knuckle arms are machined aluminium replacements intended for Tamiya TT-02B and DF-02 owners seeking a straightforward durability upgrade. The light blue finish helps with part identification while the aluminium body resists frequent wear that affects plastic knuckles.
These knuckle arms are manufactured to provide consistent pivot geometry and long service life. The aluminium material reduces the chance of fracture under normal hobby use and simplifies maintenance cycles by lowering replacement frequency.
Installation is direct on compatible TT-02B and DF-02 chassis using standard tools. After fitting, confirm smooth hub rotation and correct drive shaft clearance. Periodic inspection of mounting hardware and pivots will keep the assembly functioning reliably.
