Is it safe to buy undercarriage parts that are cheaper than OEM?

Expert_Answer

Price alone tells you nothing — what matters is whether the manufacturer builds to the OEM's dimensional and hardness specifications. The critical, invisible property is heat treatment: hardening depth on pins, bushings, rail surfaces and roller treads determines service life, and it cannot be judged from a photo or a price tag. Legitimate independent manufacturers publish specifications, state material grades, and stand behind fitment; the risky end of the market copies geometry but saves cost on steel and hardening, which shows up as rapid wear within the first thousand hours. Ask for the specification sheet, check the manufacturer is identifiable and accountable, and compare cost per operating hour rather than sticker price. VANROCK publishes its specifications and quotes per machine model through appointed dealers.
