Detailed Description

Dorman 929-938 is a suspension coil spring set engineered for rear applications that see frequent heavy hauling. The 5160H alloy construction and XHD suspension grade are selected for durability in demanding service, while the variable spring rate helps the rear suspension maintain control when carrying cargo or operating in work conditions.

What It Helps Address

• Need for a higher-load rear spring replacement

Installation Notes and Tips

Install on the rear suspension only for the listed severe heavy-duty applications. Verify spring orientation, end type, and ride height before installation. Because coil springs store significant energy, use proper spring service tools and follow factory service procedures during removal and installation. Confirm vehicle trim and suspension configuration against the fitment data before ordering.
