Hi Damian, I'm glad to assist you. No. It is for a 6-foot bed length. We do not carry a 5-foot-7-inch length bed. Still, you might need other parts such as a brake disc and pad kit (front and rear) or upgraded ceramic brake pads. We have these parts in stock. Please tell us if you need any of these parts so we can send you a link for you to click and order the part, if ever. I hope this helps.

Hi Kane, thank you for reaching out. Lower the tailgate and measure from the inside edge of the tailgate (when closed) to the inside edge of the bed at the cab, following the bed floor, not over the top rails. This measurement should not include the tailgate itself. Bed lengths are often rounded in descriptions, so a “6-foot bed” might actually measure closer to 6.5 feet (around 78 inches).
