Vehicle modifications, as well as aftermarket parts, are commonly excluded from standard policies. You may need supplemental coverage specifically for aftermarket parts or modifications. Typically, this will be through custom parts coverage. The amount can vary depending on your car’s modifications but often is between $1,000 to $5,000.
Should your car insurance company not offer custom parts coverage, shop around. Most major companies offer some form of coverage, so it shouldn’t take long to find a policy that suits your needs.
