But this 5.5-tonner is one to treat carefully: the earliest SK55SRX ran a 72-link track, and the SK55SRX-7 (plus some late -6E builds) moved up to 76 links. Width and pitch never change; the link count drifts with each generation.
Two minutes counting links, or a serial number check, beats a wrong delivery. Confirm against the size moulded inside your current track before you order.
FAQs
What size rubber track fits a Kobelco SK55SRX-6?
400×72.5×74. Early SK55SRX machines ran 400×72.5×72, and the -7 (plus some late -6E builds) run 400×72.5×76.
How do I know if my SK55SRX takes 72, 74 or 76 links?
Count the links on your current track or send us the serial number. Width and pitch are identical across all three, so the link count is the only difference.
What do Kobelco SK55SRX rubber tracks cost?
From £659 + VAT per track, whichever link count your machine runs.
Do you deliver to my part of the UK or Ireland?
Yes — we supply across the UK and Ireland, and your quote shows the delivered price to your site or yard before you commit. Nothing gets added after the fact.
