Lrichy Proportional Trailer Brake Controller 8508211 — 1–4 Axle (2/4/6/8 Brakes), LED Display & Plug‑and‑Play

The Lrichy 8508211 is a proportional electric trailer brake controller that senses vehicle braking and applies smooth, matched braking force to trailers with 1–4 axles (2/4/6/8 brakes).

This upgraded Lrichy controller replaces the Brake-EVN 8508220 and improves on older time-delay designs like the 8507111 by using built-in sensors to proportionally match trailer braking to your tow vehicle. The unit supports 2, 4, 6 or 8 brakes and fits a wide range of trucks and SUVs from Ford, GM, Chevy, Dodge/RAM, Toyota, Jeep and more. It includes a digital LED readout, manual lever control, mounting hardware, and a plug-and-play style port for fast disconnection. Note: vehicle-specific harnesses are not included.

How does the Lrichy 8508211 adjust braking for different driving conditions?

The controller uses internal motion sensors to detect deceleration and applies trailer braking force proportionally, so braking is responsive to light stops and heavy braking alike. It automatically compensates for hill starts and reductions in speed, providing consistent feel and improving stability.

• Sensor-driven proportional braking that mirrors your vehicle's deceleration
• Automatic adaptation to uphill/downhill grade changes
• LED diagnostics show real-time status and error codes
• Manual lever lets you add brake force or test the trailer brakes
