Volvo Rear Leaf Spring 23425818

Searching for direct factory replacement Volvo Rear Leaf Spring 23425818 assemblies to supply heavy commercial fleets, mining dump trucks, or international Volvo spare parts inventory? Engineered with premium high-tensile alloy spring steel, 90mm width profile, and computerized heat treatment, our heavy-duty tandem rear bogie springs deliver exceptional load-bearing capacity, maximum shock absorption, and extended service life under continuous off-road and heavy haulage operations. Certified under strict ISO/TS 16949 quality management systems with European CE compliance, Haishuo is a direct OEM factory manufacturer supplying truck parts importers, mining fleet operators, and aftermarket distributors worldwide.

Product Overview

The Volvo Rear Leaf Spring 23425818 is a high-capacity rear suspension component engineered specifically for heavy-duty Volvo commercial vehicles. Mounted on the rear tandem balance trunnion axle assembly, this heavy-duty leaf spring pack evenly distributes high dynamic loads across both rear drive axles while enabling smooth suspension articulation over unpaved construction sites, mining haul roads, and regional highways.

Forged from high-tensile alloy spring steel, every Volvo Rear Leaf Spring 23425818 manufactured by Haishuo features eye-less flat slipper ends designed to slide smoothly against heavy axle contact pads. Each leaf pack undergoes computerized quenching and tempering, precision center-hole alignment, and high-stress surface shot peening to prevent metal sagging, blade cracking, and dynamic fatigue failure across demanding haulage environments in Europe, South America, Australia, Asia, Africa, and the Middle East. We offer direct wholesale bulk manufacturing as well as custom engineering based on client technical drawings or physical samples.

Key Features & Product Highlights

100% Direct OEM Fitment (23425818): Precision-engineered dimensions matching original Volvo heavy truck rear trunnion axle seats and mounting brackets.
Standard 90mm Width Profile: Exact 90mm width and 53mm stack thickness configuration with a 1.63m total length for heavy tandem rear suspension systems.
Eye-Less Flat Slipper Ends: Smooth flat contact ends accommodate extreme axle movement over uneven mining roads while minimizing bracket friction wear.
High-Tensile Forged Alloy Steel: Manufactured from premium alloy spring steel (51CrV4 / 60Si2Mn / SUP9) for maximum yield strength, impact toughness, and fracture resistance.
Computerized Thermal Processing & Shot Peening: Advanced heat treatment and surface shot peening eliminate surface micro-fissures to maximize operational fatigue life.
Anti-Corrosion Industrial E-Coating: Protected with high-durability black electrophoretic coating (E-coating) to resist road salt, mud, water, and site corrosion.

Volvo FH / FH16 Series: Long-haul heavy tractor units operating under high-load trailer configurations.
Cross-Reference OEM Part Numbers: 23425818 and associated regional Volvo OE variants.

(Because bogie spring stack configurations can vary depending on exact regional tonnage ratings, please verify your part numbers or physical sample specs with our technical sales team.)

Common Signs Your Volvo Rear Spring Needs Replacement

Routine inspection of rear tandem bogie springs prevents severe frame twisting, axle misalignment, and costly breakdown downtime in heavy transport operations. Replace your Volvo Rear Leaf Spring 23425818 if you observe the following issues:

Visible Fractures or Snapped Center Leaves: Cracks appearing around the center pin clamping area caused by severe off-road shock loading.
Vehicle Leaning or Sagging Rear Axles: The truck sitting lower than normal under load due to lost arch elasticity.
Distorted Trunnion Slide Contact: Deep grooving or severe surface wear on the plain slipper ends where the spring contacts the axle seat.
Severe Metallic Clunking Noises: Heavy metallic knocking sounds during rough terrain travel caused by loose center bolts or shifted leaves.
Accelerated Drive Axle Tire Wear: Rapid or uneven tread wear across middle and rear drive tires caused by unbalanced load distribution.

Technical Inspection & Quality Control

Every Volvo Rear Leaf Spring 23425818 undergoes strict multi-stage quality control checks matching original equipment manufacturer standards:

3D Geometry & Arch Verification: Precision laser measurement of total length (1.63m), free arch height, leaf width (90mm), stack thickness (53mm), and center pin positioning.
Hydraulic Load & Deflection Testing: Tested on dynamic hydraulic presses to verify exact spring rate, dynamic load capacity, and flexural recovery under max load.
Metallurgical & Hardness Testing: Hardness testing verifies uniform heat treatment grain structure and dynamic tensile resilience across all stacked leaves.

Manufacturing Process

Raw Steel Inspection: High-tensile alloy spring steel flat bars undergo chemical composition analysis and tensile strength testing.
CNC Cutting & Hot Profiling: Precision shearing, end profiling, and center bolt hole punching.
Quenching, Tempering & Shot Peening: Computerized thermal treatment maximizes structural toughness, followed by shot peening to prevent fatigue micro-cracks.
Coating & Stack Assembly: Leaves receive a durable black E-coating finish before precision assembly with heavy-duty center hardware.
Final Inspection & Packaging: 100% visual, dimensional, and dynamic load-deflection checks prior to export shipping.

Packaging & Export Shipping

Anti-Rust Protection: Treated with rust-inhibiting coating and wrapped in heavy moisture-proof plastic film.
Non-Fumigation Plywood Pallets: Secured on heavy-duty non-fumigation export pallets for rapid customs clearance at destination ports.
High-Tensile Steel Strapping: Bound firmly with heavy steel bands and protective corner guards to guarantee zero shifting during ocean transit.
Container Space Optimization: Customized packing plans to maximize loading capacity in 20ft and 40ft HQ containers.
