The Hellwig Pro-Series helper spring uses the Silent Support System to provide up to 2,500 lb of level load capacity and quieter operation for Ford F-150 models. Its over-axle mounting design streamlines installation and tuning, making it a practical choice for half- and three-quarter-ton use. Check fitment if factory contact overload springs are present; the spring pair is backed by limited lifetime coverage and designed for repeat heavy-duty use.
