This is the SWORKz factory replacement rear sway bar for the S12-3 series 1:10 2WD buggy platform. The bar measures 1.5mm in diameter, placing it on the softer end of the tuning range for reduced rear roll resistance. It is formed from a single piece of metal wire bent to match the rear suspension geometry of the S12-3. Selecting the correct diameter allows tuners to dial in handling balance for different track surfaces and conditions.
