Jerky stops disappear thanks to the TriFlex NEXT’s built-in 3-axis accelerometer. It senses how fast your tow vehicle slows down and applies your trailer brakes in perfect proportion. If you brake lightly, the trailer eases in; if you stomp on the pedal, it matches that force instantly. That balance keeps braking smooth and steady across all conditions. It works with up to 4 axles (8 brake assemblies) and supports both electric and electric-over-hydraulic brake systems.
Space is tight under a modern dash, but this controller fits right in. The unit mounts flush with the included bracket and sits just 1" thick, so it doesn’t knock your knees or clutter up the cab. Automatic leveling means it can mount at nearly any angle as long as you can reach the manual override trigger. The plug-in connection makes installation straightforward when using a vehicle-specific adapter harness.
Dial in exactly how your trailer responds using two simple rockers. The gray rocker sets maximum braking output from 0.5 to 9.9 in 0.5 increments, while the black rocker adjusts how aggressively the brakes reach that output on a scale of 1 to 9. Higher load settings stop heavier trailers faster; lower settings keep lighter trailers from jerking you forward. Once set, the controller remembers your adjustments for consistent performance.
The bright LED display shows gain levels, sensitivity settings, and diagnostic codes so you always know what’s happening with your trailer brakes. You can dim it or turn on night mode to cut glare on evening drives. Full text readouts make troubleshooting straightforward without digging through menus or flashing light patterns.
The TriFlex NEXT constantly monitors for shorts or wiring faults and protects against reversed polarity or power surges. It even prevents brake overheating during long stops by reducing power output after a few seconds of hold time. After five minutes of inactivity, it slips into sleep mode to minimize battery draw, then wakes up instantly when you hit the brakes again.
