For a 7k trailer axle leaf spring solution the best we can offer is the Dexter leaf spring part # DX74XR which is rated for up to an 8k axle and is 24-7/8 inches long. You'd need to measure your current springs to verify if this length would work but it is our only potential solution. You should measure from spring eye to spring eye without a load on the spring. There isn't a way for us to look up what length springs your trailer came with.
