The GPM SAV1052H Alloy-7075 Front/Rear Arm Lock Plate is engineered for precision fitment on the HPI Savage 21. Manufactured from 7075 aircraft grade aluminium, the component is machined to tight tolerances to reduce play and improve structural rigidity.
Designed with performance in mind, the 7075 alloy plate increases torsional stiffness at the suspension mounts and helps maintain geometry under high loads. The result is crisper handling and reduced component stress during demanding running.
With CNC finished faces and accurate hole locations, this lock plate installs as a direct replacement without the need for custom fitting. The durable material choice and professional machining extend service life and resist wear in harsh conditions.
Ideal for serious hobbyists and tuners, the GPM SAV1052H Alloy-7075 Arm Lock Plate offers a reliable upgrade path that focuses on longevity, repeatable fitment, and improved chassis behaviour under load.
