The best choice for you will depend on your specific needs and budget. If you are looking for a strong rear end that can handle heavy towing or off-roading, then the 12-bolt or 14-bolt rear end is a good option. If you are on a budget or do not need a particularly strong rear end, then the 10-bolt rear end is a good choice.
When installing a rear end from another vehicle, it is important to make sure that the rear end is the correct width for your Suburban. You will also need to make sure that the rear end has the correct gear ratio for your vehicle. If you are not sure which rear end is right for your Suburban, it is best to consult with a qualified mechanic.
