This alloy steering block set is produced for HPI Savage 21 chassis as an RC-scale replacement and upgrade option. The parts replace the standard plastic steering blocks at the front and rear steering locations, offering a metal alternative intended to reduce wear on mounting points and keep steering geometry consistent during track use and maintenance.
Installation follows the stock mounting pattern so the blocks fit common Savage 21 steering link layouts without chassis modification. The alloy material provides a firmer mounting surface for steering linkages, which helps maintain alignment under load and simplifies recurring setup checks during tuning sessions.
In practice these blocks are used when replacing worn steering components or when moving toward a more durable steering assembly for frequent running. They serve a tuning role by preserving the intended steering geometry, making it easier to dial in toe and castor settings when preparing the truck for bashing or timed runs.
