Honda CRX Radius Arm

Honda CRX Radius Arm allows nimble hatchback to remain stable by securing front suspension and preventing wheel from sliding forward or backward under throttle or braking. The Radius Arm links the axle end with the chassis, guiding the longitudinal motion and thus the driver feels clear steering and predictable grip. Built out of stamped steel or in some cases aluminum, the Radius Arm remains light, reducing unsprung weight and aiding the compact Honda in making quick direction changes. In all CRX generations, Honda preferred a simple longitudinal Radius Arm, as the arrangement is well-suited to the short wheelbase, and the wheel dive and hop are kept in check. Heavier trucks adopt transverse ones for lateral centering or wristed ones for additional articulation. Compared with a 4-link setup, the CRX Radius Arm setup is less complex in terms of parts, weighs less, packages much easier, but is prone to twisting caster through heavy swings in the suspension, which with off-road rigs is solved with the multi-link style. All in all, this simple connection allows CRX drivers to enjoy crisp, light, and confident road manners that feel distinctly Honda.
