Dexter Marine Products 81103 Free Backing Solenoid

The Dexter Marine Products 81103 Free Backing Solenoid is a reverse lockout solenoid designed specifically for trailer brake systems equipped with disc brakes. This essential component automatically disengages the brakes when backing up, preventing damage and allowing smooth reverse operation.

Key Features:

• Automatic brake lockout functionality for reverse operation
• Prevents disc brakes from engaging during backing maneuvers
• Essential for disc brake systems that generate full braking power in both directions
• Designed for marine trailer applications
• Direct replacement solenoid from Dexter, a trusted name in trailer brake components

Since disc brakes generate full braking power in reverse—unlike drum brakes that are less effective when backing—this solenoid is critical for proper system operation. It ensures your trailer brakes remain disengaged while reversing, protecting the brake system and providing smooth, controlled backing.
