Buying a GM 1171500 1956-1960 Buick differential pinion gear with a 5.526 ratio (hereafter referred to as the pinion gear) can be a worthwhile investment for those restoring or working on these classic Buick vehicles. However, like any purchase, it comes with its advantages and disadvantages.

3. Availability: Buying a new OEM pinion gear can save you the time and effort of searching for a used one, which may have unknown wear or damage.

1. Cost: New OEM pinion gears can be more expensive than used alternatives. However, the cost may be justified by the reliability and peace of mind that comes with a new OEM part.

2. Lead Time: Depending on the supplier and availability, it may take some time to receive the pinion gear after placing an order.

3. Installation: Installing a new pinion gear can be a complex process that requires specialized tools and knowledge. Hiring a professional to perform the installation may add to the overall cost.
