Hey guys ! I installed a snow track set on my 550 UTV last year and it does a great job even though the engine is not that big. Broke 2 wheel studs so I temporatily replaced them with bolts but I would like to go back to the studs before reinstalling the tracks this winter. Any idea what the default studs are so I can order replacements ? Thx ! Edit : Any reseller to recommend if I want to order them online in Canada ?
