This aftermarket alloy upper spring perch fits HPI Savage 21 shock assemblies and is supplied as 1pr with part code SAV13170/USP. It takes the place of the original upper spring seating and is intended for suspension tuning and repair duties on Savage 21 models.
The aluminium perch gives a more rigid mounting point than polymer alternatives, helping to keep springs aligned and reducing movement during rough running. It is a practical choice when you need a more robust spring seat for frequent setup changes.
Simple to fit with basic RC hand tools, the part should be matched to your shock geometry prior to installation. Use caution and common-sense workshop practice when removing and refitting shock top components. This product is intended for RC suspension maintenance and tuning only.
