The engine is easy to install, and it’s been running flawlessly, giving me plenty of power for off-road fun. If you’re looking for a reliable engine to upgrade or build a custom ride, this one is definitely worth it! Highly recommended!

The engine runs incredibly smooth and delivers great power. The 4-speed transmission with reverse electric is a huge bonus, making it super easy to handle when backing up or tackling tricky terrain.

The 4-speed semi-auto transmission makes shifting easy, and having reverse is a game-changer—no more struggling to turn around in tight spots.
