This is a pack of six E-clips produced by GPM for use with HPI Savage 21 scale models, intended as direct replacement hardware for small shaft grooves and axle retention points on that chassis.
E-clips secure components on grooved shafts; these parts serve as simple retention clips for wheel hubs, axle pins, and other rotating linkages that rely on groove retention. Keep spare clips in your tool kit to restore proper axial retention after wear or during routine maintenance.
When replacing an E-clip, align the clip with the shaft groove and snap it into place; ensure it sits fully in the groove before running the model. These clips are a low-impact maintenance item, focused on restoring mechanical retention rather than changing tuning characteristics.
