Ultima® is now offering the new “El Bruto®” Series Engines which are designed to provide our customers with a U.S.A. built High Performance engine that is priced to be the best value of any engines now on the market. Ultima’s commitment to engineering excellence and competitive pricing brought El Bruto® to life with a completely new designed set of castings emphasizing performance, reliability, and value.
All of the castings in these engines are based on all-new CAD designs cast from C355 aluminum, a common U.S. military alloy known for its stability over multiple heat cycles. The engine components are machined on state of the art CNC equipment for guaranteed dimensional accuracy and repeatability. All of our engines are dynamically balanced using proprietary methods to provide the smoothest running engines on the market and now with our new high flow cylinder heads these engines now can boast the most powerful engines on the market as well!! We think that you will agree these engines are the best value anywhere. 6 Month warranty from date of purchase.
