Heavy-Duty Multi-Leaf Spring With Bushings

Product Description

This leaf spring is a heavy-duty suspension component made of multiple elastic steel plates of equal width but different lengths. It connects the vehicle frame and axle, supporting the load transmitted from the wheels while absorbing road shock and vibration. Positioned between the frame and axle, it helps maintain vehicle stability and improves adaptability to different road conditions.
The product features a durable black coating for rust resistance and a clean appearance, and is engineered for long fatigue life and reliable performance under heavy loads.

Product Highlights:

High-Strength Steel Construction: Manufactured from premium spring steel for maximum durability and load capacity.

Precision Camber Control: Computer-controlled camber selection ensures accurate fit and minimal tolerance.

Corrosion Protection: Electrophoretic or electrostatic coating provides salt spray resistance over 500 hours.

Extended Service Life: Shot peening under rated load boosts fatigue life beyond 160,000 cycles.

Secure Assembly: Heavy-duty clamps and center bolts keep the leaf stack firmly aligned under stress.

Custom Fit: Available in various materials and sizes to match specific suspension requirements.

Rust-Free Appearance: Uniform coating with full coverage and no scratches for a clean, professional look.

Product Highlights:

Robust Leaf Stack: Curved multi-layer steel plates designed for heavy-duty suspension use.

Chassis Linkage: Securely connects the frame and axle for reliable load transfer.

Shock Reduction: Dampens road impact and vibration to improve ride comfort.

Stable Performance: Enhances vehicle stability and handling on varied terrains.

Center Bolt & Clamps: Keeps leaves aligned and prevents shifting under load.

Anti-Rust Coating: Black protective finish for durability and a neat look.

Fatigue Resistant: Engineered for long cycles and extended service life.
