What is the rear shock absorber bolt size for a 2000 silverado?

There isn't a single bolt size for the rear shock absorber on a 2000 Silverado. The size depends on several factors, including the specific model (1500, 2500, 3500), the suspension configuration (leaf springs, air suspension), and even potentially the manufacturer of the shock absorber itself (if it's been replaced).

To find the correct size, you need to:

1. Consult your owner's manual: This is the best place to start. It should have diagrams and specifications.

2. Check a repair manual: A Haynes or Chilton repair manual for your specific year and model Silverado will provide detailed information including bolt sizes.

3. Look at the existing bolts: If you can safely access the bolts, measure them with a caliper or compare them to a bolt size chart. Be sure to note the thread pitch as well (e.g., 12mm x 1.75).

4. Contact a parts store: Provide them with your Silverado's year, model, and VIN. They can look up the correct parts, including the bolts, for your specific truck. This is probably the easiest method if you don't have the other resources.

Without more specific information about your Silverado's configuration, it's impossible to give you a definitive answer.
