HPI Savage 21/25/X Aluminum Fuel Tank Protection Case HSA-021 by 3Racing  [HSA-021]

Rigid aluminum tank guard

This HSA-021 aluminum fuel tank protection case is made to fit HPI Savage 21, Savage 25 and Savage X nitro RC trucks. The alloy shell creates a stiff barrier around the tank area to reduce impact damage from stones, roots and light collisions encountered in off-road running.

Fitment is restricted to the listed Savage variants; the case is an aftermarket accessory that surrounds the fuel tank area without modifying the fuel system. It is intended to integrate with the existing chassis mounting points and maintain service access.

Installation is straightforward for anyone comfortable with basic chassis work: align the case over the fuel tank zone, use the vehicle's original mounting holes and hardware, and verify there is no contact with exhaust or throttle linkages before final tightening.

Because the aluminum adds local mass and stiffness, expect a slight change in balance. After fitting, recheck ride height and suspension damping and make minor setup tweaks to preserve handling during aggressive driving.
