Review on Pioneer HB4121 Harmonic Balancer Sleeve by Black Holstead
Material too soft: Harmonic Balances
The part is very thin walled as it should be but it crumpled when I carefully tried to install it. Should be hardened or spring steel. Buy the National brand as it comes with an adjustment cup, but install with a press if you have one to keep it straight.
Pros
- Country of origin: CHINA
Cons
- Definitely bad product
