Why subscribe to PartsNX  part number interchange and cross reference services?

After 28 years of working in the automotive service industry, there is one thing that I recognize as a frustrating, time wasting, problem for all of us.  We spend huge, often non-productive time digging through the back of the catalogue hoping to identify an accurate cross to the part line we sell and recognize.  Hopefully the customer is patient and willing to wait, and that you find an accurate interchange/cross and the part is available.  PartsNX supplies this service instantly.

What if the cross reference / interchange I require is not currently in PartsNX?

PartsNX is updating and adding interchanges to the site on a daily basis.  The more cross reference data we acquire the more complete the data set will become.  We expect our customers to inform us of missing data or manufacturers on a regular basis.

Our commitment to you is we will get the data and have it available in the site as quickly as possible.

Can I list my shelf dead slow moving or surplus inventories in PartsNX so other industry players can see what I have?

Absolutely!  This is one of the sweetest bonuses in the PartsNX site.  Our classified listing area is linked to the interchange data and manufacturer list.  When posting or searching the listings, the site will automatically spider search through the interchange to identify the proper manufacturer name and part number configuration for you. Listings are posted accurately and all other listings automatically become interchanged to yours.  For example; if someone is looking for a shock absorber manufactured by Gabriel and your listing matches but is a Monroe or KYB, the site will identify this to the person searching.  They now have successfully found a matching product and can complete the sale with you.  Both the lister and purchaser have quickly found a just-in-time solution to their problem.  Our motto is “show and sell it”.

If I note a problem with an interchange what do I do to have it corrected?

Email us directly or use the “forum” to tell us and everyone else who uses the site about the problem.  Monitoring the quality of data is accomplished in two ways; first through user feed back and annotation to the particular part number listing, secondly through our direct communication with individual manufactures catalogue and technical departments.

Running changes and updates are happening on a daily basis.  How convenient and efficient would it be to know in advance which aftermarket part is a precise match and direct fit to the one you are replacing or if some modification is required before installation.   We supply an industry cross-reference, you supply the knowledge that helps others avoid wasted time and installation troubles.

Can I supply cross reference data to

Electronic formats are preferred but hard copy is welcome.For more information email

Why would I use PartsNX instead of EBay?

Good Question – PartsNX supplies detailed identification data about your part, namely its part number.  Sites like EBay allow listings with broad descriptions. No other site offers interchange / cross reference data to broaden the marketability of your part.

PartsNX is a business to business site, designed to assist the parts and repair industry. The general public can browse areas of PartsNX, however our target-market audience is the parts counter sales and installation people that work in the auto and truck repair industry.

How does PartsNX assist me in making tough sales?

Each individual manufacturer has branded names and unique part number series and configurations.  As sellers and installers of these parts we become comfortable and accustomed to dealing with numbers we recognize.  It is similar to languages that we learn and become fluent in.  A unknown part number or manufacturer is like seeing a foreign language, we don’t recognize it and can’t translate it without help.  PartsNX is the universal part number translator. “ Your part is the same as this part, this number is a direct cross / interchange to your part number”, now you are familiar with its fit and application and can supply the right part for your customer.

Can PartsNX assist me in recognizing buying opportunities?

Yes, once you recognize the availability of a direct cross / interchange to your part, you have an immediate opportunity to make a sale.  The other larger opportunity is to utilize the complete line interchange capability of PartsNX.  You can easily understand the value of a group of inventory if it can be crossed to a manufacturer part number series you recognize.  Without this understanding you take a huge risk buying bulk inventories in a part line you have no history with.
