Built for high-mileage durability, our commercial vehicle calipers utilize heavy-duty cast iron construction with triple-lip dust seals that last 3x longer than standard units. The oversized pistons (available in 60mm-80mm sizes) provide the clamping force needed for fully loaded Class 6-8 trucks. Our unique piston coating prevents stick-slip in stop-and-go delivery routes, while the one-piece design eliminates common failure points. With 500,000-mile service intervals and DOT-approved rebuild kits, these calipers keep your fleet moving with minimum downtime.
