Knowledge Center
Expert resources, buying guides, collision repair education, aftermarket auto body parts information, and industry insights from Power Auto Parts.
Products, manufacturers, articles, cities & services
Reliable answers for collision professionals and vehicle owners
The Power Auto Parts Knowledge Center exists to educate the people who make decisions about aftermarket auto body parts every day — collision estimators writing supplements, body shop managers running production, insurance adjusters approving line items, dealership collision directors comparing supply chains, fleet managers keeping vehicles in service, retail customers researching a repair, and independent technicians who want to specify replacement parts with confidence.
Every resource here is written to explain how aftermarket panels, lamps, and cooling components are engineered, how the CAPA certification program tests them, how insurers specify them in claim workflows, how the collision repair process actually moves from estimate to delivery, and how nameplate-specific fitment details affect the part that ships to your dock. The goal is a resource library that is genuinely useful — not a marketing brochure.
Read straight through, or jump to the category, product, manufacturer, or city page that matches the question you are trying to answer. Every article in the Knowledge Center connects back to the specific product, brand, and service page it describes, so you can move from concept to counter-ready part number in a couple of clicks.

Twenty of the most-asked questions
Covering aftermarket parts, CAPA certification, insurance repairs, ordering, commercial delivery, warehouse pickup, vehicle compatibility, manufacturers, cities served, and collision repair.
What is an aftermarket auto body part?
An aftermarket auto body part is a replacement panel, lamp, or component manufactured by a company that is not the original vehicle manufacturer. Aftermarket body parts are engineered to fit the same mounting points and perform the same function as the OEM component, at a lower cost point that keeps collision repairs affordable.
What does CAPA certification mean?
CAPA — the Certified Automotive Parts Association — is an independent, non-profit certification program that tests aftermarket parts against defined standards for fit, finish, material composition, and corrosion resistance. A CAPA-certified part carries a numbered yellow-and-black quality seal on the packaging and often on the part itself.
What is the difference between CAPA and non-CAPA aftermarket parts?
Both are aftermarket replacement parts. CAPA-certified parts have completed independent third-party testing under the CAPA program. Non-CAPA aftermarket parts are produced to the manufacturer's own quality standard without that specific certification and are typically priced lower. Power Auto Parts stocks both so estimators can match insurer requirements and customer budgets.
Are aftermarket parts safe to use in insurance repairs?
Aftermarket parts are widely accepted on insurance-directed repairs, and many carriers actively specify them on estimates. The vehicle owner should review their policy and consult their insurer and shop about what is being installed, but aftermarket use on insurance repairs is standard industry practice on most exterior panels, lamps, and cooling components.
How do I place an order with Power Auto Parts?
Call our parts specialists at 586-806-2110 with the year, make, model, and trim of the vehicle, or with an OEM or aftermarket part number. Our team verifies inventory in real time and confirms whether the part is available as CAPA-certified, non-CAPA, or both, then schedules commercial delivery or warehouse pickup.
Do you deliver to my shop?
We provide scheduled commercial delivery to collision repair shops, auto body shops, dealership collision centers, mechanical repair facilities, fleet maintenance operations, and commercial automotive businesses throughout Michigan, Ohio, and Indiana. Call to set up a commercial account and confirm your route.
Can retail customers pick up parts at the warehouse?
Yes. Retail customers are welcome at our warehouse pickup counter at 5523 E 9 Mile Rd, Warren, MI 48091. Call ahead to confirm inventory and to have your order staged so you are not waiting when you arrive.
How do I know a part will fit my vehicle?
Fitment is confirmed by matching the vehicle's year, make, model, trim, and options package — many nameplates have multiple sub-variants per year based on package content. Providing a VIN when you call lets our team pin down the exact SKU before the pallet moves.
Which vehicle manufacturers do you carry?
Power Auto Parts stocks aftermarket replacement body, lighting, and cooling components for 24 major nameplates including Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Honda, Hyundai, Infiniti, Jeep, Kia, Lexus, Lincoln, Mazda, Mercedes-Benz, Nissan, RAM, Subaru, Toyota, Tesla, and Volkswagen.
Which cities do you serve?
Commercial delivery routes reach Detroit, Warren, Dearborn, Troy, Ann Arbor, Grand Rapids, Cleveland, Columbus, Cincinnati, Toledo, Akron, Dayton, Indianapolis, Fort Wayne, South Bend, and dozens of additional cities across Michigan, Ohio, and Indiana. See our States We Serve pages for the full list.
Do you sell OEM parts?
No. Power Auto Parts specializes exclusively in aftermarket replacement auto body parts, including both CAPA-certified and non-CAPA product lines. We do not stock or resell original equipment manufacturer parts.
What is the typical warranty on aftermarket body parts?
Warranty terms vary by product line and manufacturer. Our parts specialists confirm the applicable warranty at the time of the order and our Warranty page outlines the general terms of coverage on aftermarket components sold by Power Auto Parts.
How long does a collision repair usually take?
Cycle time depends on damage severity, parts availability, insurer approval speed, and sublet operations like calibration and refinish. Simple bumper cover replacements can turn in a few days; structural repairs with sensor calibration can take multiple weeks. Reliable parts arrival is the single biggest cycle-time lever a shop can pull.
What is a radiator support and why does it matter?
The radiator support — sometimes called the front-end assembly or bulkhead — is the structural framework that holds the radiator, condenser, headlamps, hood latch, and front-end sheet metal. It absorbs low- and moderate-speed impact energy and often needs replacement after a front-end collision even when the bumper looks intact.
Are aftermarket headlights DOT compliant?
Reputable aftermarket headlamp manufacturers produce lamps that meet DMV and DOT lighting standards, and CAPA-certified headlamps must pass photometric and material testing under the CAPA program. Ask the counter to confirm certification status when placing the order.
Do aluminum body panels require special repair procedures?
Yes. Aluminum panels require isolated tools, dedicated repair areas to prevent galvanic contamination, and rivet-bonded or welded procedures that differ from steel. Shops that repair aluminum should follow manufacturer position statements for the specific vehicle.
How do I identify hidden damage after a collision?
Thorough teardown is the answer. Bumper reinforcement deformation, absorber compression, tie-bar kinking, radiator support cracking, and inner apron distortion often hide under intact exterior skins. Estimators who teardown early write more accurate supplements and shorter cycles.
Do you offer same-day pickup?
When a part is confirmed in stock at our Warren, MI warehouse we stage it for same-day pickup during business hours. Call first so we can pull it, tag it, and have it ready at the will-call counter when you arrive.
Can I get a quote before placing an order?
Yes. Our parts specialists provide pricing over the phone as part of the standard order process. Call 586-806-2110 with your vehicle information and we will quote CAPA and non-CAPA options where both are available.
