For competitive tuners using the Tamiya FF02 platform, the 3RACING Aluminium Universal Shaft (FF02-04) is a value racing upgrade that replaces stock plastics with a tougher metal joint. It focuses on drivetrain consistency and repeatable behaviour under load.
Aluminium construction reduces driveline deformation and preserves alignment through aggressive inputs. This helps reduce irregular power transfer and makes chassis responses easier to tune, particularly for drivers optimising corner exit and traction on various surfaces.
The FF02-04 shaft is made to fit the Tamiya FF02 geometry, allowing direct replacement in most cases. For best results, inspect spline engagement and clearance, and retest setup after installation to confirm changes in driveline stiffness are integrated into your overall tuning plan.
