Review on ACDelco 45A7121 Professional Rack Pinion by Calvin Isaac

As a hesitant buyer of this steering system product, I found it to be highly disappointing... As a result of my tests, I determined that it does not offer any significant improvement in performance as advertised. The pros of this product were minimal, as it was easy to install. However, the cons far outweighed the benefits - it was not durable and quickly broke down under normal driving conditions. Overall, I would not recommend investing in this product for your automotive needs..
