For RC drivers focused on tighter handling and more reliable landings, the XRAY 358090 Shock Foam Inserts are a practical upgrade. These inserts sit between the shock upper mount and the rubber membrane to stop membrane collapse, delivering steadier steering and better control when hitting jumps or rough sections. The pack contains four inserts to service a full car setup.
By supporting the shock membrane internally, these foam inserts reduce unwanted deformation under load so steering inputs register more predictably. That stability helps when charging through technical sections or recovering from big jumps, making lines easier to hold and lap times more consistent.
These foam pieces are compatible with many XRAY shock assemblies and work well in a variety of suspension builds. Installation is straightforward and can be completed without special tools, so even new hobbyists can upgrade their damping quickly.
