The Monster Dolly M2 by Extreme Max is a beast. This isn't the dinky little shop dolly you invite in for afternoon tea. The Monster Dolly M2 is built for hard work in the shop, an afternoon of wrenching before an evening trail ride, or a long day at the grass drags. Monster wheels - 20 inch diameter, 40 inch wide wheels with reinforced spokes mounted on double heavy-duty oversized bearings. Those features result in real lift and smoother movement on soft and uneven terrain. Monster frame - leaves room for windshields, and handlebars with risers, hooks, and mirrors and keeps your sled perfectly balanced. Monster strength - heavy gauge steel with powder coat finish. Made to maneuver the biggest sleds in shop or snow and come back for more. Monster features - adjustable lift bars with dual lift points offer maximum lift and perfect fit. Extra-wide adjustable lift strap optimizes weight distribution. Reinforced, angled dolly design combines superior strength and convenient storage. Compatible with tracks up to 21" wide and running boards up to 38" wide.
