Product Details

The CURT TriFlex NEXT is an advanced proportional electric trailer brake controller engineered for smooth, responsive stopping performance. Featuring a triple-axis, motion-sensing accelerometer, it precisely reads vehicle movement to deliver the right amount of brake force in any situation — including dynamic power adjustments when navigating uphill or downhill terrain.

With automatic leveling and calibration, there are no complex setup routines required. Simply mount it and go. Built-in reverse polarity and short-circuit protection add a layer of safety during every tow, while tow vehicle low-voltage and trailer disconnect indicators keep you informed at all times.

Key Features:

  • Triple-axis, motion-sensing accelerometer for highly responsive, smooth stops
  • Third axis provides dynamic braking power adjustments on hills and grades
  • Controls 2–8 trailer brakes (1–4 axles) with fully adjustable settings
  • 10 gain settings and 9 load settings for precise, customized braking control
  • Compatible with low-volt, PWM, ABS, cruise control, and electric-over-hydraulic brake systems
  • Automatic leveling and calibration — no manual setup required
  • Built-in reverse polarity and short-circuit protection
  • Slim, low-profile design with unique bracket system for improved dash clearance
  • Full-text LED display with diagnostics, troubleshooting, and adjustable brightness for day/night use
  • Auto-sleep mode to prevent battery drain after 5 minutes of idle time
  • Mounts anywhere in the vehicle at any angle
  • Plug-and-play installation with vehicle-specific quick plug harness (sold separately)
  • Limited lifetime warranty

The TriFlex NEXT's slim, low-profile design integrates cleanly into any cab, and the large-button interface with full-text readout makes adjustments straightforward — even on the road. A CURT brake controller wiring harness is recommended for plug-and-play installation and is sold separately.
