OEM Parts vs. OEM Procedures: What’s the Difference?

OEM parts are the factory-matched components we install during collision repair services. OEM procedures are the manufacturer’s instructions for how those parts must be installed. Your vehicle needs both; getting one without the other leaves safety gaps, even when the repair looks complete. At Redeemed Auto Body, we use OEM parts as much as possible and follow repair procedures from the manufacturer.

Key Takeaways

  • OEM parts are built to your vehicle’s original factory specifications for material, fit, and structural performance.
  • OEM procedures are the manufacturer’s repair instructions we follow on every job: weld methods, adhesives, torque specs, sequence, and required scans.
  • Industry standard: In 2011 (reaffirmed in 2017), SCRS and partner organizations recognized OEM procedures as the standard of repair for collision damage.

What Does Each One Cover?

OEM parts are replacement components built to your vehicle’s original factory specifications in material, shape, and structural performance. They meet the same tolerances and strength that the manufacturer crash-tested your vehicle around.

OEM repair procedures are the manufacturer’s technical instructions we pull for every repair: weld methods, adhesive placement, fastener torque values, fitment sequence, and required pre- and post-repair electronic scans.

What Happens When Your Vehicle Gets Only One?

OEM Parts Without OEM Procedures

Even when we source correct factory parts, how those parts are installed determines the outcome. A standard MIG weld on high-strength steel weakens the metal at the heat-affected zone. Our Prospot MIG and MAG welders are matched to the OEM-specified weld method for each job. We also run post-repair electronic scans on every vehicle. Skipped scans can leave your ADAS sensors for lane departure, forward collision warning, and automatic emergency braking miscalibrated, with no warning to you.

OEM Procedures Without OEM Parts

Aftermarket structural parts may not meet the dimensional tolerances your manufacturer designed the vehicle around. Even when we follow the correct weld sequences exactly, a non-OEM structural panel may not manage crash energy as your vehicle was built to do. Our collision center never installs aftermarket structural parts, as it compromises safety.

What to Ask Before You Authorize Collision Repair Services

  1. Do you pull OEM procedures for my vehicle’s make, model, and year?

We pull them from the manufacturer’s current database for every job, not carried over from a prior repair.

  1. Do you perform pre- and post-repair electronic scans?

Our I-CAR Platinum-certified technicians use AirPro and Opus diagnostic tools on your vehicle at the start and end of every repair.

  1. How do you document the repair for me?

We create a Google Drive folder for your job with every OEM procedure and scan result, and contact you at least twice a week throughout.

As a member of the Society of Collision Repair Specialists (SCRS), we follow the OEM standard that the industry recognized in 2011.

Frequently Asked Questions

Can my insurance company require a shop to skip OEM procedures?

No. Vehicle manufacturers set repair procedures, not insurers. We follow OEM procedures on every repair regardless of what an insurer approves. Your vehicle’s safety is governed by its manufacturer, not an estimate.

Are OEM parts always more expensive than aftermarket parts?

OEM parts typically cost more because they meet the manufacturer’s exact specifications. For non-structural components, we give you options. For structural components, Redeemed Auto Body uses OEM parts only. Cost is never a reason to compromise your vehicle’s safety.

Does using OEM parts affect my vehicle’s resale or trade-in value?

Yes. Non-OEM structural repairs can be flagged in vehicle history reports, which affects what buyers and dealers pay. If you care about resale, ask directly about the shop’s structural parts policy before you authorize the auto collision repair.
