HKS SLD (Speed Limit Defencer) Type 1

The HKS SLD is an electronic device designed to eliminate a vehicle’s factory speed limiter. When competing on the drag strip or a circuit track, the factory speed limiter can hinder a vehicle’s performance. The HKS SLD is available in two versions: Type-1 is generally for vehicles equipped with a manual transmission and Type-2 is generally for vehicles with automatic transmissions.

Legal only for use in competition vehicles which may never be registered, licensed, and/or used on public streets or highways; and also for use in other exempted vehicles.
