Both are 400mm wide, both are printed by Cat at a 72.5 pitch, and both start from £659 + VAT — so neither the width nor the pitch will tell them apart. The link count will.
Count the links on your current track, or check the size moulded inside, before any money changes hands.
FAQs
What size rubber tracks fit a Cat 305.5E?
400×72.5×76 — the same size as the 305.5D CR, 305.5E2 CR and the Next Gen 305 CR / 305.5 CR, from £659 + VAT.
What size fits a 2004–07 Cat 304 CR or 305 CR?
400×72.5×72 — the 72-link early size, replacing Cat refs 627-9473 / 588-1535.
Why does Cat show the same pitch for both tracks?
Cat prints the pitch as 72.5 across both generations, so pitch can’t identify your track. The link count is the split — count before ordering.
