Overall Assessment

The product consistently received high praise for its superior quality and aesthetically pleasing design. It boasts a sturdy build, works efficiently in various vehicles, and has an easy installation process. Customers were particularly impressed with the polished finish and chrome plating, further enhancing the vehicle's overall look. Some users highlighted its good fit, excellent workmanship, and the added 'bling' to the engine compartment. However, a few reviews pointed out that the chrome covering was prone to peel off if nicked. Despite this minor issue, the product's performance and great looks led many customers to recommend it over competitors.

Beautiful Piece

I just installed this alternator on my custom roadster and it looks great. The finishing is smooth and the chrome is bright. I can't say anything about the charging performance since my engine isn't running yet, but I am confident that it will work as great as it looks.

Cheapest chrome plating ever!

Chrome plating has no under-plate. Simply an envelope covering the alternator. Nick it and it will peel off. Don't buy this (Tuff Stuff built) for a show car. Not worth the extra money. Charges OK.
