INJGROM-11BK-INJS11
Injora INJS11 Aluminum High Voltage Micro Servo Set
Precision steering starts with the right servo, and the Injora INJS11 delivers exactly that for Arrma Grom and Losi NASCAR platform drivers. This compact, high-voltage micro servo packs serious performance into a lightweight aluminum package — pushing up to 11kg-cm (153oz-in) of torque and hitting 0.074s/60° response speed at 8.4V. A coreless motor design ensures quick, efficient actuation, while the CNC-machined aluminum case keeps things cool and rigid under load. The full steel gear train — stainless and hardened throughout — is built to handle the stresses of off-road running without skipping a beat. Water-resistant O-ring seals add an extra layer of protection for dirty, wet conditions. An aluminum 25T servo saver is included, making this a complete, ready-to-install steering upgrade.
