Sometimes one position has more than one valid part

A diagram position does not always mean one product.

You might sell the original manufacturer part and an aftermarket option for the same position. You might sell a standard version and a premium version. You might offer a genuine replacement and a budget-compatible alternative.

The customer is still looking at one part position on the diagram.

They just have more than one buying option.

Do not duplicate the marker

The wrong way to handle this is to place two markers on the same part.

That clutters the diagram and makes the customer wonder whether the two markers refer to different physical positions.

If the OEM and aftermarket products occupy the same diagram position, they should sit under the same hotspot.

Konfigr supports multiple products per hotspot for this reason.

What the customer sees

The customer clicks the marker for the part position.

In the parts list, they see the available options for that position. One might be labelled as OEM. Another might be labelled as aftermarket. They can compare the product name, image, price, and other details you choose to show.

The diagram stays clean because the position is marked once.

The choice happens in the parts list, where there is room to explain it properly.

A pool pump example

Take a pool pump impeller.

The diagram has one impeller position. You sell the OEM impeller for $85 and an aftermarket version for $45.

Both parts belong to the same position in the exploded view. They should not be shown as two different points on the diagram.

Instead, one hotspot marks the impeller. The parts list shows both options. The customer can choose based on brand, price, availability, and their own preference.

Use clear product names

OEM and aftermarket options must be labelled clearly.

Do not make customers guess which is which. If one part is genuine OEM, say that in the product name. If the other is aftermarket, compatible, or non-genuine, say that clearly too.

A vague title like “Impeller Replacement” beside another vague title like “Impeller Spare” does not help.

Use labels such as “OEM Impeller” and “Aftermarket Impeller” where accurate. If the aftermarket part has a brand, include it. If compatibility needs explanation, put that on the product page.

Price comparison should be honest

One reason to show OEM and aftermarket options together is price comparison.

If the customer sees both options in the same diagram position, they can make a practical decision. Some will choose genuine parts. Some will choose a cheaper alternative. Some will choose based on availability.

Do not hide the difference or make the cheaper part look like the same thing if it is not.

Clear labelling protects the customer and your support team.

Only group genuine alternatives

Multiple products per hotspot should be used carefully.

Only group products when they are valid options for the same diagram position. Do not group parts together just because they are related.

A seal kit and an impeller may be used in the same repair, but they are not the same diagram position. They should have separate markers.

OEM and aftermarket versions of the same part position can share one hotspot if they are genuine alternatives.

Use variant pinning when the option is inside a product

Sometimes the OEM option or aftermarket option is not a separate Shopify product. It may be a variant inside a larger product record.

If one specific variant belongs to the diagram position, pin that variant in the Konfig.

This keeps the customer from seeing variant choices that are not relevant to the part position.

Use this when your Shopify catalogue is built with variant-based part options.

Availability can affect the decision

Customers may prefer OEM, but choose aftermarket if the genuine part is out of stock.

Or they may prefer the aftermarket option but choose OEM if it is available sooner.

Showing current product information helps the customer make that decision in context.

Konfigr reads product data from Shopify, so the parts list can reflect the current product information you maintain in your store.

Keep the diagram simple and the choice clear

The diagram should answer “where is the part?”

The parts list should answer “which option do I want?”

That split keeps the page easier to understand. One marker for one physical position. Multiple products only when there are multiple valid options for that same position.

Handled well, OEM and aftermarket choices become easier for customers to compare without making the diagram messy.
