Services & Mechanical Repairs

At 3BT (Big Boys Big Toys), we understand that an American pickup is more than just a vehicle—it’s a powerhouse designed for heavy work and serious play. Located on the Sunshine Coast, we specialise in the maintenance, repair, and performance tuning of the “Big Three”: RAM, Chevrolet Silverado, and Ford F-Series and Toyota.

Our workshop is geared specifically for the unique engineering of US-spec trucks, ensuring your “Big Toy” remains reliable whether it’s on the highway or deep off-road.
