This engineered set supplies hardened steel hinge pins paired with E-clips for HPI Savage 21 models, designated SSAV1101. The kit contains six matched pairs of pins and retaining clips to replace fatigued or deformed pivot hardware at suspension arms and link mounts.
Functionally the pins act as rotating pivots for suspension and link points; installing new, straight pins eliminates excess radial play and restores intended alignment. The chosen steel grade increases bending resistance over soft-stock pins while E-clip retention permits repeatable removal and reinstallation during maintenance cycles.
Installation is a direct replacement procedure: extract the worn pin and clip, insert the replacement pin ensuring correct locating engagement, then secure with the supplied E-clip fully seated in its groove. Validate full suspension articulation and absence of binding after fitment. Maintain spare clips and pins as part of routine service spares for sustained off-road usage.
