Crews running MTX80HDR units on heavy-clay or rocky-fill applications wear shoes faster than crews working softer cohesive soils.

Multiquip uses the 11-inch wood shoe across the entire MTX70\/MTX80 platform (and MTX90 legacy). The same 8511S OEM kit fits MTX70HD, MTX70HDR, MTX70HF, and MTX80HDR.

The MTX80HDR's 3,505 lbf delivers about 4.6% higher impact force than the MTX70HD's 3,350 lbf, but the heavier operating weight (181 lbs vs ~168 lbs) compounds the effect. In practice, MTX80HDR shoe replacement intervals run 30–40% shorter than MTX70HD intervals on the same job mix.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eQ: Can I substitute an aftermarket 11-inch wood shoe?\u003c\/strong\u003e Aftermarket shoes from various Amazon and eBay suppliers are physically dimensioned to match the OEM 8511S, but tolerance accuracy, wood lamination grade, and bolt-hole alignment vary by manufacturer. For an MTX80HDR specifically, the higher impact loading punishes any tolerance slop in the shoe assembly — OEM is the lower-risk choice for fleet operators where downtime is the larger cost.\u003c\/p\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eImportant Ordering Notes\u003c\/h4\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMake sure the part numbers are correct, certain parts are serial number specific.\u003c\/strong\u003e Confirm your MTX80HDR's serial plate matches the part designation before ordering.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eContact us for parts identification and confirmation of part numbers.\u003c\/strong\u003e Send \u003ccode class=\"bg-text-200\/5 border border-0.5 border-border-300 text-danger-000 whitespace-pre-wrap rounded-[0.4rem] px-1 py-px text-[0.9rem]\"\u003ecustomerservice@danseusa.com\u003c\/code\u003e photos of your engine label, serial plate, and existing shoe assembly for verification.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCertain items may be drop shipped direct from the manufacturer.\u003c\/strong\u003e Your order may arrive in separate boxes — each with individual tracking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eAbout DanseUSA\u003c\/h4\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eDanseUSA — authorized Multiquip parts dealer since \u003cstrong\u003e1981\u003c\/strong\u003e.
