Dorman 929-931 Coil Spring - Front

Dorman 929-931 Heavy-Duty Coil Springs

Dorman 929-931 heavy-duty coil springs are built for front suspension upgrades on select Ford F-150 trucks. They increase load handling by 35% over the vehicle’s nominal spring rate and help improve ride control in continuous hauling conditions.

For 1980-1996 Ford F-150 front suspension service, this OE-style replacement supports heavier use while helping reduce driver fatigue and improve handling response.

Key Features

• Heavy-duty coil spring design for front suspension use
• 5160H alloy construction for strength and durability
• Powder-coated metallic grey finish
• Variable spring rate for load-sensitive performance
• Custom-engineered to improve ride quality under load
• Direct replacement for select Ford F-150 front applications

Detailed Description

This Dorman coil spring set is engineered for trucks that see regular hauling, towing, or other demanding service. The 5160H alloy construction and HD suspension grade help the front end maintain better support under added weight, while the variable spring rate is tuned to balance ride comfort and load control. Dorman 929-931 is a practical upgrade for owners looking to restore front suspension performance on a Ford F-150 without changing the vehicle’s basic suspension layout.

Compatible With 1980-1996 Ford F-150, front, wo/Dual Shocks Option. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Help Address

• Front-end sag from repeated heavy hauling
• Reduced ride control under load
• Excessive bounce or unsettled handling
• Driver fatigue caused by poor suspension support
• Worn or weakened original front coil springs

Installation Notes and Tips

Verify front suspension configuration before ordering, including the note for vehicles without the dual shocks option. Inspect related suspension components such as shocks, bushings, and spring seats during service. Spring replacement should be performed with proper suspension tools and standard safety procedures.

Quality Assurance

Dorman designs this heavy-duty coil spring set as a replacement part for demanding truck use. The powder-coated finish helps protect the spring surface, and the 5160H alloy material supports durability in front suspension applications.
