The welded-track design addresses this by providing exact compatibility with established lift architectures that have served shops reliably for decades, requiring no track modifications or upgrades.\u003c\/p\u003e\n\u003cp\u003eThis enables continued use of existing lift investment without replacement costs.

Blocks degrade over time with repeated compression cycles and vehicle contact. Replace blocks when they show visible flattening, cracking, or permanent deformation. Fresh blocks ensure even load distribution and protect vehicle finish during future service work.
