Dorman 929-930 Coil Spring - Rear
Heavy-Duty Rear Coil Springs for Load Control
Dorman 929-930 is an extra-heavy-duty coil spring set for vehicles that regularly carry substantial rear loads. Built from 5160H alloy with a powder-coated metallic grey finish, these variable-rate springs add approximately 2 inches of OE lift and are engineered to improve ride quality, reduce driver fatigue, and sharpen handling under continuous heavy hauling.
Key Features
- Extra-heavy-duty suspension grade for severe-duty rear applications
- 5160H alloy construction for strength and durability
- Variable spring rate for improved load handling and ride control
- Powder coat finish in metallic grey for added corrosion resistance
- OE lift of +2 in for added stance and clearance
- Pigtail over-center ends for the listed rear coil spring applications
- Fits many Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, and GMC Yukon XL rear suspension setups
Detailed Description
Dorman 929-930 is built for severe heavy-duty use on rear suspension applications where the factory spring rate is not enough. The 0.718-inch wire diameter and XHD suspension grade help the spring handle sustained cargo weight, towing loads, and other demanding conditions while maintaining more controlled ride behavior. This makes it a practical upgrade for Chevrolet Tahoe rear coil spring replacement, GMC Yukon rear suspension service, and Cadillac Escalade rear spring replacement on supported model years.
The spring set is also a fitment-based solution for GMC Yukon XL and Chevrolet Suburban 1500 rear applications, along with Chevrolet Avalanche and Avalanche 1500 rear severe heavy-duty use cases. If you are searching for Dorman 929-930 rear coil springs for heavy hauling, or a +2 inch OE lift coil spring upgrade for Tahoe, Yukon, or Escalade, this part is built around those needs.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Rear sag from frequent towing or cargo hauling
- Excessive suspension compression under heavy loads
- Reduced ride control in severe-duty use
- Uneven rear stance caused by worn coil springs
- Loss of handling stability when the vehicle is loaded
Installation Notes and Tips
Compatible With rear suspension applications only for the listed Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, GMC Yukon XL, Chevrolet Suburban 1500, Chevrolet Avalanche, and Chevrolet Avalanche 1500 model years. Verify position, trim, and severe heavy-duty application notes before installation. Because coil spring replacement affects ride height and suspension geometry, inspect related rear suspension components during service and confirm alignment after installation.
Quality Assurance
Dorman engineers this spring set for load-handling improvement over the vehicle’s nominal spring rate, using 5160H alloy construction and a powder-coated finish to support long-term service in demanding rear suspension use.
