How to select leaf spring for truck

1.Confirm working load

Calculate the rated full load of the truck,including curb weight and cargo weight.Choose heavy-duty leaf springs for overloading and frequent heavy haulage;standard specification for regular light load transport.Excessive load will cause early breakage and permanent sag of leaf spring.

2.Check original specification parameters

Arc height(camber):Keep consistent with original leaf spring to avoid vehicle height deviation and poor shock absorption.

Number of spring leaves&thickness:More and thicker leaves bear larger load;reduce pieces for lighter load to improve driving comfort.

Overall length&mounting hole spacing:Match truck suspension bracket and U-bolt installation position directly.

3.Distinguish application scenarios

Highway transport:Alloy steel leaf spring with fine heat treatment,fatigue resistant for long-distance running.

Construction site/mine/rural rough road:Thickened heavy-duty leaf spring with enhanced anti-impact performance.

4.Material&surface treatment selection

Alloy spring steel(65Mn/SUP9)is mainstream raw material with strong toughness.Electrophoresis or powder coating surface effectively prevents rust in humid and muddy environments.

5.Custom demand

If modifying truck carrying capacity,our factory can customize leaf spring length,thickness,piece count and camber as per customer’s actual requirements.
