Zero Cero Lower Suspension Arm Set Direct-Fit - O-3CP016 by 3Racing  [FP-O-3CP016]

Design notes for the lower arms

The FP-O-3CP016 lower suspension arm assembly is supplied as an aftermarket replacement compatible with the Zero Cero 1/10 chassis. It reproduces the original mount points so owners can replace worn pieces without modifying the chassis.

These arms act as the primary load-bearing link between hub carrier and chassis, influencing alignment geometry such as camber and toe when paired with shock and link adjustments. Before fitting, check the hinge-pin bores and mounting hardware for wear to avoid any unwanted binding.

Installation tip: remove the wheel and hub carrier to gain access to the lower arm pins, move over any bearings or bushings where relevant, and secure the new arms with the existing hinge pins and retainers. Verify full suspension freedom and recheck alignment after refit.

For hobbyists replacing damaged or tired arms on the Zero Cero, this aftermarket set delivers the expected geometry and mounting points; always confirm fit and alignment after installation to maintain consistent handling.
