Engine

• Dodge's Hemi engine used for the 2004 and 2005 Rumble Bee was the standard 5.7L Hemispherical head V8 engine offered in those years. While the truck was a limited edition, it did not include a special engine or any additional performance tuning to set the truck apart from other Dodge Ram pickup trucks. The Rumble Bee's Hemi V8 engine produces 345 horsepower and 375 pound-feet of torque. The engine is a cast iron block fitted with aluminum heads, and features a bore of 3.92 inches and stroke of 3.58 inches. The Hemi 5.7L V8 is set up as a 90-degree push rod-style engine.
  
  

Body

• The 2004 and 2005 Dodge Rumble Bee was only available on the short-bed single cab pickup truck produced that year. The trucks were painted either yellow or black to match the Rumble Bee emblems, and include a color-keyed front air valance, side skirts and rear air dam, which were specific to the Rumble Bee for those years. The seats are slate gray leather or cloth.
  
  

Towing and Hauling

• Towing and hauling capacity of the Rumble Bee were unchanged from stock Dodge Ram Hemi pickup trucks. These trucks are rated to tow at least 8,500 pounds with proper Class III or IV hitch mounts installed. Payload capacity of the 2004 and 2005 Dodge Ram Rumble Bee is at least 1,500 pounds.
  
  

Fuel Economy

• Fuel economy on the 2004 and 2005 Dodge Ram Rumble Bee pickup trucks fitted with the Hemi V8 engine was classified as extremely poor. These trucks, with an automatic transmission, averaged only 12 miles per gallon in the city and 17 miles per gallon on the highway, according to government fuel economy testing. The rear end gear ratio of these trucks was 3.92:1, which for many vehicles is an economy gear ratio intended to boost fuel economy numbers. The size and inefficiency of the Rumble Bee Hemi engine, however, coupled with the truck's 2 ton curb weight return low fuel economy despite the gear tuning.
