Subpar Automotive Engine Sleeve Attachment

The harmonic balancer sleeve underperformed during installation, hindering my engine's performance. While it promised better absorption of vibrations, it failed to deliver causing my car to shake violently. The product's quality and design were also subpar, resulting in a frustrating and time-consuming installation process.

Pros
  • None
Cons
  • Poor quality, ineffective vibration absorption.

Works great and is made in the USA

Fits the crankshaft hub perfectly on the 1996 Corvette LT-1 LT-1. The best part is that it's made in the USA and not cheap chinese junk.

Pros
  • Product box width: 4.75"
Cons
  • Nothing

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
