Arrma 90mm Shock Springs ARA-4463 – 0.56N/mm

Arrma Shock Springs: 90mm 0.56N/mm (3.2lbf/in) (2pcs), part number ARA-4463, are replacement shock components for maintaining or tuning suitable RC model suspension systems. The listed spring rate is 0.56N/mm, also shown as 3.2lbf/in, giving you a clear specification to compare when selecting replacement springs. This set contains two springs, making it suitable for servicing a pair of shocks where the dimensions and specifications match your model. The manufacturer categorises this item under shocks and shock parts, so it is intended as a component rather than a complete shock assembly. Please check your model’s existing shock dimensions and recommended spring rate before use, as compatibility is only suggested from the supplied information. The product name identifies the springs as 90mm items; however, the supplied box information refers to two 100mm 0.44N/mm (4.4lb/in) springs. Confirm the specification required for your application before fitting.

Key Information

These Arrma springs are supplied as a two-piece replacement set for RC suspension work. Their spring rate is provided in both metric and imperial formats, helping you compare them with existing springs or setup requirements. No complete shock bodies, dampers, fittings or other suspension hardware are specified as included, so the set should be considered limited to the springs described by the product information.

Supplied Contents

The manufacturer’s supplied contents information states that the box includes two shock springs. It describes these as 100mm springs rated at 0.44N/mm (4.4lb/in), which differs from the 90mm, 0.56N/mm (3.2lbf/in) specification in the product name. Use the specification that has been confirmed for your intended setup when assessing suggested compatibility.
