This six-piece set of E-clips is supplied for HPI Savage 21 models and functions as direct replacement hardware for small shaft grooves and axle retention features on that chassis. The pack is intended to provide reliable retention for common rotating linkages in routine rebuilds and repairs.
E-clips secure components on grooved shafts and are typically used to retain wheel hubs, axle pins and similar rotating connections. Keeping spare clips on hand reduces downtime and restores correct axial positioning after wear or mechanical service.
For installation, align the clip with the shaft groove and press until it engages; confirm full seating and check rotation for any lateral play. These clips are a service part focused on mechanical retention and fitment accuracy rather than tuning changes.
