Firm Tyre Support for HPI Savage Using 3Racing HSA-033

Owners of the HPI Savage 21 or Savage 25 can fit 3Racing HSA-033 foam inserts to 40 series tyres to stabilise the tyre carcass. The inserts help maintain shape through corners and reduce squirm at higher speeds.

Why Fit 3Racing HSA-033 Inserts?

The 3Racing HSA-033 is profiled to match 40 series tyres on Savage trucks, offering improved contact patch consistency and reduced tyre fatigue. This gives drivers clearer feedback and steadier handling across different surfaces.

Main Benefits

Compatibility: Tailored for HPI Savage 21 and Savage 25 running 40 series tyres.
Durability: Robust foam construction resists breaking down under repeated use.
Performance: Promotes even wear and steadier traction in turns and landings.

Can I glue these inserts to the tyre?

Gluing the tyre to the rim is recommended once the insert is seated, but the insert itself is usually held in place by the tyre bead.

Do these inserts alter traction on loose surfaces?

By supporting the tyre sidewall the insert can improve footprint stability, which often helps traction on loose or uneven ground.

How often should I replace the foam inserts?

Replace inserts when they show signs of permanent compression or tearing; frequency depends on run conditions and driving style.
