Product Introduction

The 6593250019 / 6253250119 Leaf Spring Seat is an essential suspension mounting component used in Mercedes-Benz SK series and Beiben NG80 heavy-duty trucks.

Installed between the chassis frame, axle beam, and leaf spring assembly, the spring seat provides a secure mounting position for the leaf spring while transferring vehicle weight and road impact forces through the suspension system.

The leaf spring mounting works together with:

• Leaf spring assembly
• Rear axle housing
• Balance shaft assembly
• Suspension saddle
• U-bolt
• Spring plate
• Rubber cushion pad
• Suspension bracket

Its primary functions include:

• Supporting and positioning the leaf spring
• Transferring axle loads to the chassis
• Maintaining suspension geometry
• Reducing suspension movement and vibration
• Improving vehicle stability under heavy loads

Heavy-duty trucks operating in transportation, construction, mining, and difficult road conditions generate continuous impact forces and vibration. A damaged or worn leaf spring seat may cause:

• Leaf spring displacement
• Suspension abnormal noise
• Uneven axle loading
• Reduced driving stability
• Premature wear of suspension components
• Increased chassis stress

The 6593250019 / 6253250119 spring mounting seat is manufactured from high-strength steel with precision casting and machining processes. The mounting surfaces and connection points are produced according to OEM specifications, ensuring accurate installation and reliable performance.

Designed as a direct replacement component, this leaf spring mounting provides excellent compatibility with Mercedes-Benz SK and Beiben NG80 heavy trucks. It is widely used for suspension repair, chassis rebuilding, fleet maintenance, and heavy commercial vehicle applications.

Each leaf spring seat undergoes strict quality inspections including:

• Material strength testing
• Casting quality inspection
• Dimensional accuracy verification
• Mounting surface inspection
• Load-bearing test
• Installation fitment verification

to ensure OEM-level durability, safety, and long service life.
