HRATF18MX01 - Heavy Duty Motor Mount Arrma 1:10 4x4 3s 4S Blx

Adjustable, heavy‑duty motor mount engineered to replace the stock composite unit on 1/10 scale ARRMA 4×4 BLX trucks running on 3S or 4S brushless power systems. Machined from aluminum to provide greater rigidity and resistance to flex under high torque loads, improving gear alignment and drivetrain longevity. Features an adjustable slider section so you can fine‑tune gear mesh for optimized pinion and spur gear engagement. Integrated heavy duty brace ties the motor mount into the chassis structure to resist movement under load and reduce drivetrain wear. Designed for direct fitment on popular ARRMA 4×4 BLX platforms including Granite, Big Rock, Senton, Vorteks, Outcast, and Kraton families.
