• Description:

  This Genuine Ford front coil spring, cataloged as Spring Front under base 5310, is a front suspension coil spring for the F-250 and F-350 Super Duty pickup on the solid front axle used from 2008 onward, with additional application to the heavier F-450 and F-550 chassis. It carries the weight of the front of the truck, establishes ride height, and absorbs road inputs while the shock absorber controls rebound and the radius arm locates the axle. Ford produces base 5310 in several distinct spring-rate codes so the spring matches the front-axle load rating and equipment the truck was built with; this suffix is a specific new-production rate variant, not a remanufactured part and not a leaf spring. Owners replace a front coil spring when the truck sags, sits noticeably lower on one side, has lost ride height after carrying heavy front-mounted equipment, rides harsh or bottoms out, or has a broken or corroded coil. Because ride height and handling depend on installing the correct rate code, match this spring to your truck's front-axle rating and the corner being serviced. As a genuine Ford component it is wound to the original wire diameter, coil count, and free length so it restores factory ride height and load capacity rather than sitting too high or too low. The front springs are under heavy preload, so a proper spring compressor and careful handling of the shock and radius-arm fasteners are required for safe service, and it is good practice to inspect the shocks and front-end hardware while the spring is out.
