The 3Racing F113-134 differential balls are intended for competitive setups where consistent rolling performance matters. This 18 piece set is a serviceable upgrade for the F113 chassis that supports repeatable diff response during intense running and tuning cycles.
Precision sizing helps reduce variability in torque transfer and supports stable tuning adjustments. Maintaining a set of correctly sized balls simplifies setup work and ensures the differential reacts predictably to tuning changes.
For best results, replace the full set during rebuilds and verify clearances as part of your setup routine. Using matched balls from the 3Racing F113-134 pack reduces the chance of uneven wear that can complicate fine tuning.
