rental car damage and liability insurance

Custom parts and equipment coverage (CPE) is an optional endorsement that you can add to your standard auto insurance policy. CPE provides additional coverage for aftermarket parts and accessories that you have permanently installed on your vehicle. These can include parts that alter the performance, appearance, or function of your vehicle beyond what was originally installed by the manufacturer. CPE supplements your existing collision and comprehensive coverage, and may be subject to the same deductibles. It covers non-OEM parts added by a dealer or third party. This section will provide an overview of CPE and what it covers.

What is Covered by CPE

CPE provides coverage for various aftermarket parts and accessories that are permanently installed on your vehicle. Here are some examples of parts that would be covered:

  • Custom wheels and tires: This includes alloy, magnesium, or aluminum wheels not installed by the manufacturer. It also covers custom spinners, custom wide-tread tires, oversize tires, and racing slicks.

  • Spoilers: Aftermarket spoilers and wings would be covered.

  • Performance parts: Upgraded or customized components related to performance are covered, such as:

    • Suspension parts like lowering kits, coilovers, or air suspension

    • Turbochargers, superchargers, intake and exhaust systems

    • ECU tuning and engine mods

    • Brake upgrades

  • Custom paint and decals: Any paint job, decals, graphics, or wraps would be covered if damaged. This includes custom colors, murals, stripes, and more.

  • Anti-theft devices: Alarm systems, steering wheel locks, brake locks, wheel boots, and other anti-theft devices added after purchase.

Electronics like TVs, DVD players, and screens installed by a dealer would also be covered, provided they are permanently mounted.

Other examples of special equipment that CPE would cover includes:

  • Running boards

  • Fog lights

  • Bed liners

  • Hitches

Engine, suspension, brake mods


Aftermarket seats, steering wheels


Radios, TVs, GPS, cameras


Lifts, racks, guards, hitches

In summary, CPE covers a wide range of aftermarket parts, provided they are permanently installed by a dealer or third party shop. It does not cover maintenance or repairs.

III. Relationship to Other Coverages

Custom parts and equipment coverage supplements your existing collision and comprehensive auto insurance. It is important to understand how CPE interacts with these other coverages.

  • Collision coverage pays for damage to your vehicle from a collision with another car or object. This covers the original manufacturer parts only. CPE adds coverage for any aftermarket parts you've added.

  • Comprehensive coverage pays for damage to your vehicle that is not a collision - like theft, vandalism, weather, fire, or animals. Again, it only covers stock parts, while CPE adds coverage for custom parts.

  • CPE does not replace or fulfill your state's minimum required liability coverage. Liability coverage pays for damage you cause to others and is mandatory. CPE is an optional add-on.

  • Like collision and comprehensive coverage, CPE claims may be subject to your deductible. If you have a $500 deductible and make a CPE claim for $2,000 in damage, you would pay $500 and insurance would cover the remaining $1,500.

  • CPE also may apply separate limits or exclusions from your main policy coverages. Make sure to understand if parts are excluded or have lower limits under CPE.

Examples of how CPE interacts with other coverages:

  • Your car with $2,000 in aftermarket parts is totaled. Collision coverage pays the value of the stock vehicle. CPE pays the $2,000 for the custom parts.

  • Someone steals your car stereo covered by CPE. Comprehensive coverage would pay for the OEM stereo, while CPE pays for the upgraded stereo.

  • You cause an accident that damages another car. Liability coverage pays for the other car, while collision coverage pays for damage to your OEM parts. CPE covers your custom parts.

  • A tree branch falls and damages your custom hood and spoiler. Comprehensive coverage pays for the OEM hood, while CPE pays for the custom hood and spoiler.

As you can see, CPE works with your existing collision and comprehensive coverage to provide additional protection for aftermarket parts. It does not replace or fulfill state minimum liability coverage requirements. Contact your insurer to learn about CPE deductibles, exclusions, and limits.

Types of Parts Covered

CPE covers a wide variety of aftermarket parts and equipment added to your vehicle. Here are some of the main types of parts that would be covered:

  • Custom wheels and tires: Aftermarket rims, spinners, alloy wheels, racing tires, and wheel covers added after purchase are covered. This includes:

    • Aluminum, alloy, or magnesium custom wheels

    • Wheel covers like chrome, wire-spoke, or custom finishes

    • Special tires like oversize tires, mud terrain tires, or racing slicks

    • Upgraded brake systems

  • Interior parts like aftermarket seats, steering wheels, shift knobs, and custom upholstery added by a dealer are covered.

  • Audio equipment: Aftermarket stereos, speakers, amplifiers, and audio accessories added after purchase are covered. For example:

    • High-end stereos and speakers from brands like JBL, Alpine, Pioneer, etc.

    • Built-in amplifiers and subwoofers

    • Side/rear entertainment systems

  • Navigation systems: Aftermarket GPS navigation systems, mapping software, and hardware are covered.

  • Driver aids and sensors: Backup cameras, proximity sensors, lane departure warning systems, and other driver aids added later are covered.

  • Exterior: Running boards, fender flares, hood shields, and upgrades added later are covered.

As you can see, CPE covers many sorts of special equipment, from towing accessories to bed liners, disability equipment, and interior/exterior upgrades. Review your policy language and consult your insurer to verify coverage.

Dealer vs Manufacturer Parts

A key aspect of CPE is that it covers parts added by dealers and third parties, not the original manufacturer.

  • Parts installed by the manufacturer are covered under standard insurance. For example:

    • Wheels, transmission, stereo installed at the factory

    • Options like sunroof, leather seats, Bose audio ordered from the manufacturer

  • Parts added afterwards by a dealer or other party are eligible for CPE. For example:

    • New wheels, tires, lift kit added by dealership

    • Aftermarket stereo, speakers, amp added by electronics shop

    • Bed liner, brush guards added by truck accessory store

Some examples comparing manufacturer vs dealer/third party parts:

  • The manufacturer offers leather seats and a sunroof as options. These are covered by standard insurance. The dealer-installed remote start is covered by CPE.

  • The manufacturer offers 18" wheels. 20" custom wheels added later by the dealer would be covered by CPE.

  • The factory stereo and speakers are covered by regular insurance. An aftermarket stereo installed afterwards is covered by CPE.

There are a few exceptions:

  • Manufacturer parts ordered as accessories through dealer may be covered under standard insurance. Verify with insurer.

  • Dealer must be authorized if installing manufacturer accessories. Unauthorized alterations may not be covered.

CPE covers the parts added after the initial purchase, while standard insurance covers OEM parts. Verify who installed parts in question and whether CPE applies when filing a claim. Consult your insurer with any uncertainties.

Coverage Limits

CPE endorsement have limits on the amount of coverage provided. Understanding these limits is important when considering CPE.

  • CPE limits typically range from $1,000 to $10,000 depending on your policy and state. Higher limits may be available.

  • The limit caps the amount that can be claimed for custom parts under CPE. Any costs above the limit are your responsibility.

Examples of CPE limits:

  • Your policy has a $2,000 CPE limit. You have $3,000 worth of aftermarket parts that are damaged. CPE will cover only $2,000, leaving you to pay the remaining $1,000.

  • You have $15,000 in custom parts and purchase a $5,000 CPE limit. If damage occurs, your coverage maxes out at $5,000. You would owe the remaining $10,000.

  • Your state caps CPE at $1,000 per policy. Even if you pay for higher limits, claims over $1,000 will be denied.

Important considerations regarding CPE limits:

  • Limits can vary by type of part. For example, electronics may be capped lower than body kits or wheels.

  • Choose limits carefully based on total value of custom parts. Insufficient limits leave you underinsured.

  • Limits may need to be increased over time as you add more custom parts.

  • Deductibles still apply on top of limits. A $500 deductible on a $2,000 limit would cover only $1,500.

  • Exclusions may exist regardless of limits, like racing parts. Make sure parts are covered.

Adding CPE to Your Policy

If you have aftermarket parts on your vehicle, here is how you can add CPE coverage:

1. Contact your insurance provider

  • Call your agent or insurer's customer service.

  • Ask to add a CPE endorsement or rider to your existing auto policy.

2. Review options and pricing

  • Insurer will explain available coverage limits and pricing.

  • Make sure limits adequately cover total value of custom parts.

  • Consider any deductibles that apply.

3. Provide details on custom parts

  • Give insurer a complete list of aftermarket parts on your vehicle.

  • Note those that alter performance or functionality.

  • Provide any paperwork from dealers/shops who installed parts.

4. Confirm coverage

  • Have insurer confirm in writing which parts are covered.

  • Verify if any parts are limited or excluded.

  • Save written confirmation with your policy documents.

5. Adjust coverage as needed over time

  • Increase CPE limits if you add more custom parts.

  • Remove CPE if you remove parts or sell vehicle.

Tips for adding CPE:

  • Inform insurer any time parts are added to maintain coverage.

  • If switching insurers, make sure to get CPE on new policy.

  • Install parts properly to avoid denial of coverage.

  • Avoid hiding parts from insurer. Disclosure prevents issues later.

  • Read Endorsement documents carefully to understand coverage.

You must communicate all details on your custom parts to your insurer and buy appropriate CPE limits to get coverage. Adjust as needed when modifying your vehicle further.
