Important Note for Bolt Kits:

For vehicles equipped with a welded ring gear, the installation process requires the removal, drilling, and installation of the welded ring gear from your stock differential. This intricate task should be entrusted to a professional machine shop. To seamlessly install the ring gear onto the new differential, you'll need Bolt Kit ES4368731. It's imperative to consult your machine shop before purchasing this item and the necessary hardware kit.

Please be aware that no technical drawings or instructions are provided, underscoring the importance of verifying compatibility and ensuring correct installation with your chosen machine shop. Refunds or replacements will not be offered in the event of incorrect ring gear installation or differential failure due to improper installation.
