It mainly comes down to different quality levels of the chassis, even if they have the same specifications. The quality can be categorized into:
High quality (premium):
Made with good materials, precise welding, and well-designed. These chassis are strong, resistant to rust, and durable, lasting a long time under normal use.
Medium quality (standard):
Made with decent materials and average craftsmanship. These are okay for regular use but are more prone to rust, cracks, and deterioration over time.
Low quality (poor):
Made with inferior materials, rough welding, and poor design. These are fragile, rust easily, and tend to crack or deform quickly, causing problems and failures in a short period.
Why do lower quality undercarriage tend to fail faster?
Material issues: Poor materials can't handle daily loads, leading to deformation or cracks.
Bad craftsmanship: Weak welds or inadequate assembly can create weak points.
Design flaws: Poor design leads to stress concentration and early damage.
Poor corrosion resistance: Insufficient rust-proofing causes rust and accelerates deterioration.
In summary:
The lifespan and durability of a chassis mainly depend on its quality level. Higher-quality materials, better craftsmanship, and proper design result in a longer-lasting chassis. Cheaper, lower-quality ones will break down much sooner.
So, when choosing a chassis or vehicle, it's important to pay attention to quality to avoid early failures.
