Dorman 929-905 Coil Spring - Front
Dorman 929-905 Extra-Heavy-Duty Coil Springs
Dorman 929-905 is an extra-heavy-duty coil spring set built for vehicles that carry constant weight and work in demanding conditions. With a 70% increase in load handling capability over the vehicle’s nominal spring rate, it is a direct upgrade for pickup trucks, SUVs, RVs, plow trucks, vans, and similar heavy-duty applications.
These XHD coil springs use 5160H alloy steel, a constant spring rate, and a powder-coated metallic grey finish to support load control while helping improve ride quality and handling. The semi-closed plain ends and 0.937 wire diameter are engineered for consistent suspension performance, and the OE lift is +1.7 in.
Key Features
- Extra-heavy-duty coil spring design for continuous hauling conditions
- 70% increase in load handling capability over nominal spring rate
- 5160H alloy construction for suspension durability
- Constant spring rate for predictable response under load
- Powder-coated metallic grey finish
- Semi-closed plain ends on both ends
- OE lift: +1.7 in
- Suspension grade type: XHD
Detailed Description
Dorman 929-905 is engineered for drivers who need firmer rear or front suspension support without changing the vehicle’s basic spring architecture. It is a practical choice for heavy hauling, towing, service use, and other duty cycles where standard coil springs can sag or lose control under repeated load. For buyers searching for Dorman 929-905 coil springs for pickup truck suspension upgrade, heavy-duty SUV spring replacement, or van load support, this part is built around those needs.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Search terms such as Dorman 929-905, heavy-duty coil springs for trucks, and XHD coil spring replacement are commonly used by shoppers comparing suspension upgrades for work vehicles.
What It Helps Address
- Rear or front suspension sag from frequent hauling
- Reduced ride control when carrying heavy cargo
- Excessive body movement under load
- Uneven handling after spring fatigue
- Need for a higher-load coil spring replacement
Installation Notes and Tips
Verify spring dimensions, end style, and OE lift before installation. Because coil springs store significant energy, use proper spring compression tools and follow factory service procedures. Inspect related suspension components such as mounts, isolators, shocks, and control arms during replacement to confirm the system is ready for service.
Compatible With heavy-duty pickup truck, SUV, RV, plow truck, and van suspension applications where the original spring rate is no longer sufficient. For shoppers comparing Dorman 929-905 against other load-rated coil spring options, confirm vehicle-specific dimensions and suspension configuration before ordering.
Quality Assurance
Dorman engineers this spring set as a suspension replacement for demanding load conditions, using 5160H alloy material, powder coating, and an XHD spring specification to support consistent performance in work-oriented use.
