Coil Helper Spring is a supplementary inner spring fitted within the rear coil suspension to increase load-carrying capacity.
Seating inside the main rear road spring, the helper spring provides additional rate for heavy-duty applications, supporting greater payload and resisting rear-end sag under load. It supplements the main coil rather than replacing it, raising the effective spring rate of the rear suspension.
