Off Road Monster Wheels M24 GBML Gloss Black | 20x10 -19mm | 8x165.1/8x180 Dual-Drilled | HD Truck Wheel
Is This for You?
You're running an HD truck on either the 8x165.1 (8x6.5") or 8x180 bolt pattern — Ram 2500/3500, pre-2011 GM HD, or 2011+ Silverado/Sierra HD — single rear wheel — and you want a 20" gloss black wheel that covers both bolt patterns with a single SKU. The M24 GBML at 20x10 with -19mm offset delivers a moderate stance that works well on leveled and mildly lifted HD builds. Cast aluminum 1-piece construction, 125.2mm hub-centric bore, 3,500 lb load rating.
