This aftermarket alloy lower chassis is built for compatibility with HPI Savage 21 models and is supplied as a 1pr set including an extra titanium dog bone, mounting screws and Delrin collars. It is aimed at drivers who want a more robust lower plate to support altered suspension geometry and driveline linkages without changing the basic Savage 21 layout.
The 4.75mm alloy plate provides increased torsional rigidity relative to common stamped steel parts while keeping weight appropriate for most off-road builds. The extra titanium dog bone (1pcs) serves as a spare driveline component and arrives with the fasteners and Delrin collars for immediate fitting or trial setups.
Installation guidance: this part replaces the factory lower chassis on Savage 21 cars, interfaces with existing suspension mounts and driveshafts, and requires routine RC hand tools plus a check of clearance for steering and travel before full assembly.
Ideal for track or trail builds that need a firmer lower plate and a spare titanium dog bone for Savage 21 upkeep; always confirm fit against your existing shock and driveline components before finishing the install.
