HPI Savage 21/25 Graphite Side Rails by 3Racing HSA-001/1  [HSA-001/1]

Upgrade Chassis Stiffness with 3Racing HSA-001/1

Owners of HPI Savage 21 and Savage 25 can fit the 3Racing graphite side chassis to gain a more rigid platform. The graphite construction keeps weight down while adding structural integrity, making the truck feel more planted through technical sections and jumps.

Why Graphite Works Well

Graphite offers a good balance of rigidity and low mass, which helps maintain sharper handling without a heavy penalty. Racers and weekend drivers alike will notice steadier steering inputs and a reduction in flex that can confuse chassis balance.
