Dorman 929-916 Coil Spring - Front

Dorman 929-916 Heavy-Duty Coil Springs

Dorman 929-916 coil springs are built for front suspension applications that see frequent heavy loads. This OE-style replacement uses 5160H alloy steel, a constant spring rate, and a powder-coated metallic grey finish to help maintain ride height and improve control in demanding service.

Compatible with front suspension applications on Chevrolet P30, Chevrolet C3500, Chevrolet G30, Chevrolet C35, Chevrolet C30, GMC C3500, and GMC G35 models across the listed years, this part is a direct-fit solution for heavy hauling and commercial use.

• 5160H alloy construction for heavy-duty suspension service
• Constant spring rate for consistent front-end support
• Powder coat finish for added surface protection
• Pigtail over center end on one side and semi-closed plain end on the other
• Front suspension coil spring replacement for standard-rate applications
• Fits many pickup trucks, vans, RVs, and plow trucks used in continuous load conditions

Built For Load Handling

This Dorman coil spring pair is engineered to provide a 35% increase in load handling capability over the vehicle’s nominal spring rate. The result is improved support for front suspension systems that carry sustained weight, while also helping reduce driver fatigue and improve handling response. Dorman 929-916 is a practical upgrade for Chevrolet and GMC commercial platforms that need more consistent front-end performance under load.

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

Common Problems It Can Help Address

• Front-end sag from repeated hauling or service-body use
• Reduced ride control under constant load
• Excessive suspension compression on heavy-duty vehicles
• Poor handling stability when carrying equipment or cargo
• Uneven front ride height caused by worn coil springs

Installation Notes And Fitment

Fits 1975-2005 Chevrolet P30, front; 1988-2000 Chevrolet C3500, front; 1988-2000 GMC C3500, front; 1979-1986 GMC C3500, front; 1975-1995 Chevrolet G30, front; 1983-1987 Chevrolet C35, front; 1975-1986 Chevrolet C30, front; and 1975-1978 GMC G35, front. Verify spring seat condition and suspension height before installation. Professional installation is recommended because coil springs are under high tension and require proper compression tools.
