Ultimate Racing M-4R

Manufacturer: Ultimate Racing
SKU: UR3301-4R

The Ultimate Engines M-4R is a 4 port engine with tuned crankshaft and represents the most powerful and fast 1/8 off-road engine of the Ultimate Engines line.  The Modelix Racing R&D team worked hard to develop an engine that takes what they learned from the M-5 and M-8 to further improve fuel mileage, reliability, and overall performance.  The M-4R has all what an engine needs to compete against other market leading engines, but at a price point that is well below what you normally will pay for a top quality race engine.

The M4-R is designed by Modelix Racing and built by Novarossi.
