Original Parts Groups Explained

An Original Parts Group (OPG) is a network of independent automotive parts distributors and retailers that sell genuine manufacturer parts under a shared brand and purchasing structure. Unlike a single company, OPG operates as a cooperative or franchise system where member shops buy inventory together to negotiate better prices from manufacturers, then sell those parts to repair shops, dealerships, and consumers under the OPG name.

The group model lets smaller parts retailers compete with large chains by pooling their buying power. When you see "Original Parts Group" on a storefront or website, you are dealing with a member business that has agreed to stock certain inventory, follow pricing guidelines, and meet service standards set by the network. The actual ownership and operation of each location remains independent.

OPG primarily serves the collision repair and mechanical repair industries, though some locations also serve do-it-yourself customers. The parts themselves are genuine OEM (original equipment manufacturer) parts — the same components that come from the factory — not aftermarket substitutes or refurbished units.

Key Takeaways

  • Original Parts Group is a network of independent distributors that buy and sell genuine manufacturer parts under a shared brand, not a single company.
  • Member shops use the OPG network to purchase inventory at negotiated rates, which they then resell to repair facilities and the public.
  • OPG parts are genuine OEM components, meaning they come directly from the vehicle manufacturer or an authorized supplier, not aftermarket alternatives.
  • Each OPG location is independently owned and operated, so pricing, hours, and service levels can vary between member shops.
  • The network model allows smaller retailers to offer competitive pricing and inventory depth that would be difficult for a single independent shop to maintain alone.

How the OPG Network Structure Works

OPG operates through a tiered system. At the top, the Original Parts Group organization sets standards, negotiates manufacturer contracts, and manages the brand. Below that are regional or local member distributors — these are the actual businesses you interact with. Each member distributor may also have sub-dealers or retail locations that buy from them.

When a repair shop or consumer needs a part, they contact their local OPG member. That member checks their inventory or orders from the OPG network warehouse. The part is then shipped to the customer or picked up at the location. Because members buy collectively, they receive volume discounts from manufacturers that a single independent shop could not negotiate alone.

This structure means that while all OPG members carry the same brand and follow the same general guidelines, each location sets its own retail prices, hours of operation, and service policies. Two OPG shops in different cities may quote different prices for the same part, and one may offer next-day delivery while another does not.

OPG Parts Versus Aftermarket and Rebuilt Options

Original Parts Group sells only genuine OEM parts — components manufactured by the vehicle maker or an authorized supplier. These are new, unused parts that meet the exact specifications the manufacturer designed for that vehicle model.

Aftermarket parts, by contrast, are made by third-party manufacturers and may not meet the same tolerances or durability standards. Rebuilt or reconditioned parts are used components that have been cleaned and restored to working condition. OPG does not stock these alternatives; if you want an aftermarket or rebuilt part, you would need to go to a different supplier.

For collision repair work, insurance companies and repair shops often prefer OEM parts because they fit precisely and carry manufacturer warranties. For mechanical repairs, some shops use aftermarket parts to reduce customer cost. OPG's focus on OEM inventory means it serves shops and customers who prioritize fit and warranty coverage over lowest price.

Finding and Ordering from an OPG Location

To locate an Original Parts Group member near you, visit the OPG website or call their customer service line. They maintain a directory of member locations organized by region. You can search by zip code or city to find the nearest distributor.

Once you identify a location, you can call, visit in person, or order online through their website. Most OPG members accept phone orders and can ship parts or hold them for pickup. If you are ordering for a repair shop, you may need to provide your shop's account information or tax ID. If you are a consumer ordering for personal use, you typically pay retail price and may be able to pick up same-day or next-day depending on whether the part is in stock.

Pricing varies by location and by current manufacturer costs, so it is worth calling ahead if you need a quote. Some OPG members also offer installation services or can recommend local repair shops, though this depends on the individual location.

When OPG Is the Right Choice

Original Parts Group makes sense when you need genuine OEM parts and want to support an independent distributor rather than a large national chain. If your repair shop already has an account with a local OPG member, ordering through them is straightforward and often faster than going through a dealership.

OPG is also useful if you are doing a repair that requires exact fitment — collision work, engine rebuilds, or any job where a part must match factory specifications precisely. The OEM warranty that comes with OPG parts protects you if a component fails prematurely.

For budget-conscious repairs where exact fitment is less critical, aftermarket parts from other suppliers may be cheaper. For rare or discontinued parts, a dealership parts department may have better access than a local OPG member. OPG fills the middle ground: genuine parts at independent-shop pricing with a network-wide inventory system.

OPG Pricing and Warranties

OPG parts carry the manufacturer's warranty, which typically covers defects in materials or workmanship for a set period — usually one to three years depending on the part type and manufacturer. This warranty is the same whether you buy from OPG, a dealership, or any other authorized distributor.

Pricing at OPG is generally lower than dealership pricing because OPG members buy in volume and operate with lower overhead than a franchised dealer. However, OPG prices are usually higher than aftermarket parts from discount retailers. The difference reflects the cost of genuine OEM components and the service level of the OPG network.

Some OPG locations offer their own return or satisfaction guarantees on top of the manufacturer warranty. Ask your local member about their specific policy before ordering.

Frequently Asked Questions

Is Original Parts Group the same as the dealership parts department?

No. OPG is an independent network of distributors, while dealership parts departments are owned and operated by the franchised dealer. Both sell genuine OEM parts, but OPG typically offers lower prices because members buy collectively and operate independently. Dealerships may have faster access to rare or brand-new parts because they order directly from the manufacturer.

Can I return a part to OPG if it does not fit or I ordered the wrong one?

Return policies vary by OPG location. Most allow returns within a set period — often 30 days — if the part is unused and in original packaging. Some locations charge a restocking fee. Call your local OPG member to confirm their specific return policy before ordering.

Do all OPG locations carry the same inventory?

No. Each OPG member maintains its own inventory based on local demand and storage capacity. However, members can order from other OPG locations or the central warehouse if a part is not in stock locally. This usually adds one to three business days to delivery time.

Can I order OPG parts online for delivery to my home?

Many OPG locations offer online ordering and shipping to residential addresses. Visit the OPG website or contact your local member to see if they ship to your area and what delivery times and costs explore. Some locations offer free shipping on orders above a certain amount.

What if I need a part for a vehicle that is no longer in production?

OPG members can often source discontinued or hard-to-find parts through their network and manufacturer contacts. Call your local OPG location with the vehicle year, make, model, and part number. They can tell you whether the part is available and how long it will take to obtain.
