Dexter Axle K23-657-00 12x2 Electric Brake Kit Right Hand FSA Tow Assist

The Dexter Axle K23-657-00 is a 12" x 2" Right-Hand (passenger side) Electric Brake Kit featuring Dexter's Forward Self-Adjusting (FSA / Nev-R-Adjust) technology with Tow Assist compatibility. Engineered for reliable, low-maintenance trailer braking, this kit delivers consistent stopping power while automatically maintaining proper brake shoe adjustment — eliminating the need for routine manual adjustment.

The FSA (Forward Self-Adjusting) design continuously calibrates brake shoe clearance with each braking cycle, ensuring optimal contact and performance over the life of the brake. The Right-Hand designation indicates this assembly installs on the passenger side (curb side) of the trailer. The Tow Assist feature provides enhanced integration with tow vehicle brake controller systems for improved sway control and braking response.
