These are direct replacements for the failure prone stock mounts. The urethane inserts can be replaced later if need be for a fraction of the cost of the kit. these mounts offer same NVH as stock but are much, much stronger. Center bolt shown is only for reference and is NOT included, you will reuse the factory bolt. We do not include instructions as this gets replaced just like a factory part. These are sold AS A PAIR and include free shipping in the 50 states, International shipping is extra.
