Product Details
SINOTRUK HOWO Rear Leaf Spring Assembly (WG9719520020)
⚙️ Complete High-Tensile Multi-Leaf Rear Suspension Assembly for Heavy-Duty Fleet Rehabilitation
Product Overview
In deep-pit mining extraction, aggregate hauling, and heavy-load regional logistics, the rear axle suspension bears continuous, extreme structural stress and violent kinetic shocks. When an individual leaf leaf succumbs to fatigue or micro-cracks, it leads to rapid axle misalignment, uneven tire wear, and compromised vehicle stability. At ARCHER, we distribute premium factory-direct SINOTRUK HOWO Rear Leaf Spring Assemblies (Part Number: WG9719520020). This complete multi-leaf assembly is engineered from high-grade silicon-manganese spring steel, tempered and shot-peened to deliver extraordinary load-bearing capacity and fatigue resilience. Featuring a multi-layered structure with robust center alignment pins and heavy-duty retaining clips, this suspension unit ensures reliable frame support under continuous maximum payload configurations.
Comprehensive Fleet Applications & Chassis Configurations

Our rear spring assemblies arrive pre-assembled with individual leaves accurately aligned, center bolts pre-torqued, and robust guide clips swaged to original engineering specifications. This layout ensures immediate workshop integration into standard equalizer groups and rear axle housing seats.
Why Source Leaf Spring Assemblies from ARCHER?
🛡️ Premium Silicon-Manganese Steel
Our suspension components utilize premium spring alloy formulations, undergoing controlled heat treatment matrices to optimize yield strength and eliminate premature brittle fracturing under load.
🛡️ Advanced Shot-Peening Surface Treatment
Every individual steel leaf layer undergoes automated dual-sided shot-peening treatments, which increases surface fatigue life and neutralizes micro-stress cracks caused by bumpy terrain.
🛡️ Corrosion-Resistant Interleaf Coating
The assembled spring plates are treated with anti-friction protective coatings, minimizing interleaf wear, preventing rust build-up, and ensuring quiet, consistent flexing operation.
Technical FAQ
1. Does part number WG9719520020 represent a standard highway spring profile or a reinforced mining version?
The WG9719520020 part sequence is engineered as a heavy-duty multi-leaf suspension profile optimized for excellent stability. It features reinforced leaf cross-sections suited for vocational configurations like heavy dump trucks and concrete mixers. To verify if your chassis matches this specific setup, we recommend checking your original rear suspension nameplate or providing your vehicle VIN.
2. Is it necessary to replace rear leaf spring assemblies in pairs across the same axle?
Yes. ARCHER strongly advises fleet managers to change rear suspension assemblies in tandem pairs (left and right sides simultaneously). Installing a brand-new spring group opposite an older, fatigued unit will lead to uneven load distribution, chassis lean, asymmetrical steering behavior, and accelerated wear on related axle hardware.
3. Does the assembly come complete with the U-bolts, spring shackle pins, and bushes?
The WG9719520020 is shipped as a complete pre-bound multi-leaf pack with its center pin and retaining alignment bands. Accompanying heavy-duty chassis U-bolts, hardened shackle pins, equalizer assemblies, and polyurethane or bronze bushes can be bundled into your order separately through our sales support division.
