GSI INTERLOCK ULTRA
FLAGSHIP CONTROL. INTEGRATED LED MATRIX.
Meet the GSI Interlock Ultra, the flagship configuration of GSI's modular Interlock system.
Its distinctive 300 mm rim integrates the LED Matrix directly into the design, creating a clean, purpose-built racing interface with dynamic visual feedback for supported gear, flag, and alert animations.
The control layout delivers 42 mappable inputs through 12 RGB push-buttons, two thumb encoders, two tactile 5-way encoders, and two 7-way switches. Available N52 shifters and HSE clutches provide additional configuration options.
Up to 90 addressable RGB LEDs combine illuminated controls with a 4 + 15 + 4 telemetry strip, while the integrated LED Matrix adds another layer of customizable visual information.
A matte brushed aluminium front plate, aluminium unibody, perforated faux leather handles, and scratch-resistant polycarbonate buttons complete the lightweight, performance-focused construction.
The Interlock Ultra is also ready for passthrough USB-C quick-release systems, including the upcoming GSI Powerlink-QR, with dynamic power switching between compatible passthrough QR and coiled-cable connections.
