Heavy Duty Front Leaf Spring

The General Spring KC 43-516HD is a heavy-duty front leaf spring engineered to enhance the suspension capabilities of 1980-1997 Ford F350 4WD trucks equipped with a solid front axle. This heavy-duty leaf spring offers an increased capacity of 3,000 lbs per spring, which is an 800 lbs upgrade compared to the standard OEM replacement (43-516). It is constructed with a specific leaf grading: 2 Leaves @ 0.750″, 1 Leaf @ 0.702″, and 1 Bottom Steel Pad @ 0.262″, totaling 3 leaves and 1 pad. The spring measures 3 inches in width, with a short end length of 23-7/8 inches and a long end length of 28-3/8 inches. The pack thickness is 2-1/2 inches and it has a 3-inch arch. Designed as a direct OEM replacement, this spring maintains the original length while incorporating a tapered leaf for improved capacity. It comes with front and rear pressed-in leaf spring eye bushings included, ready for installation. The spring eye bolt size is specified as 9/16″ x 5″ Grade 8. This heavy-duty front leaf spring is specifically designed for Ford F350 4WD Pickup models from 1980 through 1997 that feature solid front axle suspension. It cross-references with OEM part numbers E5TA5310NA, E5TANA, E5TZ5310K, F5TA5310HA, and F5TAHA.
