CURT 51146 TriFlex NEXT Proportional Trailer Brake Controller
CURT 51146 TriFlex NEXT uses a triple-axis accelerometer to proportion trailer braking and supports 2–8 trailer brakes across 1–4 axles. It is for 12-volt vehicle systems; a suitable vehicle-specific wiring harness is sold separately.
Product Description
The low-profile housing and bracket are designed to improve dash clearance while the display provides full-text diagnostics. Automatic leveling and calibration simplify orientation, but gain and load settings still need to be adjusted for the actual tow vehicle and trailer. Voltage and trailer-disconnect indicators help identify connection problems.
Features & Benefits
- Triple-axis proportional sensing, including dynamic adjustment on grades.
- Supports 1–4 axles / 2–8 brakes.
- Ten gain and nine load settings in the current product data.
- Adjustable display brightness and day/night mode.
- Automatic leveling, reverse-polarity and short-circuit protection.
- Auto-sleep after five minutes of idle time.
Compatibility & Applications
- 12-volt vehicle system, operating range 9–16 volts.
- For compatible electric trailer-brake systems; current supplier data also identifies electric-over-hydraulic compatibility.
- Select the correct vehicle harness separately; a universal controller is not proof that every connector plugs in directly.
- Confirm the trailer brake and vehicle wiring configuration before installation.
Before ordering
Wiring harness is separate. Automatic calibration does not replace gain/load setup or the brake test described in the controller instructions.
