An all-electronic virtuoso of braking technology, the SpeedBrake’s plug-in connection makes for a clean and simple installation without cutting or tapping into vital wire harnesses. No need to crawl under your truck to cut up the exhaust system — no mechanical “adjustments” necessary to insure its function. SpeedBrake uses the trucks own components giving you the safety needed with no added mechanical parts to fool around with or second guess.
SpeedBrake has no competition and makes no compromises. As a smart device, the SpeedBrake becomes an active component of your vehicle, constantly monitoring and adjusting systems achieving the speed you set. Using its patented technology the SpeedBrake controls your transmission’s shifting, locks and unlocks the torque converter and infinitely varies the VG turbo’s vanes to hold your set speed and maximize stopping performance to ensure that you have the safety and confidence for the long haul.
