HPI Savage 21 Titanium Drive Adaptor 5mm With Pins by GPM TSAV1010  [TSAV1010]

Drive adaptor for Savage 21

This 4pcs set of titanium drive adaptors is a scale RC replacement part made for HPI Savage 21 owners who need a compact, durable coupler for the driveline. Each adaptor matches the 5mm shaft interface and includes the retention pins required to secure the adaptor on the driveshaft, so it can be used as a direct spare or during routine maintenance at the track.

Installation is straightforward on Savage 21 drivetrains: slide the adaptor onto the 5mm shaft, align the pin holes, and insert the supplied pins to lock the piece in place. Use a clean work area and basic hex driver to access the driveshaft; verify pin seating and that the adaptor spins freely on the shaft before reassembling the drivetrain.

In tuning or repair contexts these adaptors serve as a lightweight, corrosion-resistant option to replace worn or damaged factory parts, and they are sized and fitted for typical Savage 21 driveline geometry. They are sold as a 4pcs set to allow multiple axle positions or to keep spares on hand for track-side swaps.
