Review on Royalo Harmonic Installer Installation Crankshaft by Michael Dominguez
Disappointing Performance Car Engine Part
As an automotive enthusiast, I was excited to test this product but it failed to meet my expectations. My analysis of this product showed that it didn't deliver the promised horsepower boost and I was left with a subpar engine performance. The only pro i could find is that the installation process was NOT too difficult .The main con however, is that the product didn't live up to its claims, making it a waste of money..
- Improved engine performance with better harmonic balance
- Requires professional installation for best results
