HPI Savage 21 Upgraded 4.75mm Alloy Chassis with Titanium Dog Bone SAV1014VL by GPM  [SAV1014VL]

Upgraded 4.75mm alloy chassis for Savage 21

This aftermarket 4.75mm alloy lower chassis fits HPI Savage 21 vehicles and is supplied as a 1pr set that includes an extra titanium dog bone, screws and Delrin collars. It targets hobbyists looking for a firmer lower plate to support modified suspension geometry and driveline linkages while retaining Savage 21 compatibility.

The thicker alloy plate improves stiffness compared with typical stamped steel alternatives while keeping weight suited for off-road tuning. The included titanium dog bone (1pcs) is an extra driveline pin provided with the mounting screws and Delrin collars so you can swap worn parts or test different setups without sourcing additional small hardware.

Fitting notes: this component is intended as an upgrade or replacement lower chassis for Savage 21 models, it connects to existing suspension mounts and driveline components, and installation uses common RC hand tools plus a clearance check for steering and suspension travel.

Use this chassis plate when you need a stiffer lower deck and a spare titanium dog bone for Savage 21 maintenance or stepwise tuning; always verify clearance with your shocks and driveline before final assembly.
