Detailed Description

This Dorman 43-478 leaf spring assembly is engineered for front suspension use on select Ford trucks, including Ford F-250, Ford F-250 HD, and Ford F-350 applications. The assembly uses a steel spring pack with a 3-inch leaf width, black bushings, and a standard replacement design to restore front-end support where the original spring has weakened, sagged, or lost ride control. The listed fitment includes 1980-1997 Ford F-250 front, 1980-1984 Ford F-350 front, 1985-1997 Ford F-350 front with independent front suspension, and 1997 Ford F-250 HD front.

This part cross-references OE-style numbers including E0TA5310ACA and E0TZ5310S for the same application. The Dorman 43-478 is a direct-fit suspension service part for owners addressing front ride height, payload support, and steering stability on older Ford truck platforms.

What It Helps Fix

• Uneven ride height caused by worn leaf springs
• Reduced load-carrying support in the front suspension
• Excessive bounce or poor road control from fatigued spring packs
• Noise or looseness related to worn spring bushings
