About this part

The Tamiya 1/14 Grand Hauler Semi Kit replicates the real-world vehicle recreates a massive boxy, customized truck like those seen in North America. The model's ladder frame chassis features aluminum side channels with resin cross members and is equipped with a highly realistic suspension utilizing metal leaf springs and friction dampers. A front-mounted motor and 3-speed transmission power the two rear wheel axles, which are fitted with built-in differentials to enable smooth cornering. A 4-channel R/C system and multi-function unit allow you to drive the vehicle and experience realistic lights, sounds and vibrations.

Headlights, brake lights, fog lamp, hazard lights and turn signal operations are also at your fingertips.

Well AMain again shows there true colors they are only selling these kits to hobby shops and letting them gouge us on price instead of actually selling them. Hundreds available on flea bay and all supplied thru AMain distributing per my invoice.

Best Hobby shop by far in the USA. Deal with a live perrson and never feel rushed cause if you do you rushed yourself. They take all of the time you need to solve the problem you have if your RC. This company believes in old schoo;. What I mean is call and choose to speak to someone and that will happen. I extremely los A Main Hobby. Thank you for what you are "the best in the business" Gary from south Florida.

Do NOT buy these trucks until Tamiya can reliably stock replacement parts. Bevel gears are unobtainable, and have been so for months. This wouldn't be a problem if they weren't made of the most garbage metal known to man. Tamiya 5455065 is an "updated" part that ships with the heavy haul trucks. Problem is, I bought the final three units Tamiya had months ago. Still no stock. These kits are awesome, but they're tarnished by a company who doesn't seem to give a damn. EDIT: Tamiya is getting serious, and parts are becoming plentiful again! Keep it up, Tamiya!

Alejandro OlmosVerified owneron Tamiya 1/14 Grand Hauler Semi Kit (Unpainted)

AWESOME build and best price online! When you finish and see your masterpiece, it will leave anyone wanting to know how in the world did you build that. There are many YouTube videos how to build with tips and tricks. I provided a video show casing my Grand Hauler/MFC with a the RC4WD LowBoy Trailer.

What reviewers say

Reviewers broadly praise the Tamiya 1/14 Grand Hauler Semi Kit's build experience, detail and fit, with several describing it as enjoyable and high quality. Shipping speed and retailer service, particularly from A-Main Hobbies, are also commonly praised. Disagreement centres on sourcing and support: one reviewer reports that replacement bevel gears (Tamiya 5455065) were out of stock for months, describing the metal as weak, though a later edit says parts are becoming available again. Another reviewer criticises A-Main for allegedly restricting supply to hobby shops and pricing high, while others describe the price as good. One reviewer also warns that the screws are JIS head rather than Phillips, so the correct driver is needed. One review reports difficulty reaching phone support.

  • + Good level of detail and fit
  • + Enjoyable build experience
  • + Fast shipping
  • + Friendly, helpful retailer service
  • − Replacement bevel gear stock shortages
  • − Gears reported as weak metal
  • − Screws are JIS head, not Phillips
  • − Phone support hard to reach
