Why Choose the Off‑Road Version?
AL‑KO’s Off‑Road electric brake backing plates are built for Australia's toughest towing conditions. The reinforced plastic-core magnet absorbs vibration and extends magnet life—reducing brake chatter, uneven wear, and early replacements.
If you're towing over corrugations, unsealed roads, or tackling 4WD tracks, these are a must-have upgrade over standard electric brakes.
