For hobbyists looking to refine a Serpent 748, this 2.2mm rear antiroll bar is a practical upgrade that trims unwanted roll. It suits drivers who want steadier behaviour through corners and clearer feedback from the rear end.
Specifically matched to the Serpent 748 chassis, the 2.2mm bar offers enough stiffness to control roll while still allowing the rear to find grip. That compromise helps keep lap times consistent across changing track conditions.
Fit the bar with care, checking link lengths and mounting hardware for symmetry. Small mismatches can cause uneven response, so confirm alignment and retest after a few runs.
