Dorman 929-945 Coil Spring - Front

Dorman 929-945 Heavy-Duty Front Coil Springs

Dorman 929-945 front coil springs are built for Ford Super Duty trucks that see continuous hauling, towing, or other demanding front-end loads. This suspension upgrade increases load handling by 70% over the vehicle’s nominal spring rate while helping improve ride control and reduce driver fatigue.

Key Features

• Extra-heavy-duty coil spring design for front suspension use
• 70% increase in load handling capability over nominal spring rate
• 5160H alloy construction with powder-coated finish
• Constant spring rate for consistent front suspension response
• OE lift of +3 in for a taller front stance
• Metallic grey finish with pigtail over center and semi-closed plain ends
• Fits 2005-2025 Ford F-250 Super Duty, front, standard rate
• Fits 2005-2025 Ford F-350 Super Duty, front, standard rate

Detailed Description

Built for heavy-duty service, Dorman 929-945 uses 5160H alloy steel and a powder-coated finish to handle repeated front suspension loading in pickup trucks, SUVs, RVs, plow trucks, and vans. The constant-rate design helps maintain predictable front-end support, while the extra-heavy-duty spring rate is suited to vehicles that spend long periods carrying weight. This part number is a direct fit for Ford F-250 Super Duty and Ford F-350 Super Duty front suspension applications with standard rate springs.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end sag from frequent hauling or towing
• Reduced ride control under sustained load
• Excessive suspension compression on work trucks
• Poor handling response from worn or underspecified springs
• Uneven front ride height on heavy-duty Ford Super Duty trucks

Installation Notes and Tips

Verify front suspension configuration and standard-rate application before ordering. Because this spring set provides an OE lift of +3 in, confirm ride height and alignment requirements after installation. Use proper spring compression tools and follow factory service procedures for safe removal and replacement.

Quality Assurance

Dorman engineers this coil spring set for heavy-duty suspension service using 5160H alloy and a corrosion-resistant powder coat finish. The constant-rate design and application-specific fitment support consistent performance on Ford F-250 Super Duty and Ford F-350 Super Duty front suspensions.
