When your vehicle needs suspension work, finding the right replacement part is critical. OEM (Original Equipment Manufacturer) part numbers are the standard identifiers for factory components, but aftermarket brands like Ultra-Power offer high-quality alternatives at a fraction of the cost. This guide walks you through how to cross reference suspension OEM part numbers with Ultra-Power equivalents, ensuring you get the correct part every time.
Understanding OEM Suspension Part Numbers
OEM part numbers are alphanumeric codes assigned by vehicle manufacturers to identify specific components. For suspension parts, these numbers appear on the original part itself—often stamped into the metal or printed on a sticker—and in your vehicle’s service manual or parts catalog. Common suspension components include struts, shocks, control arms, tie rod ends, sway bar links, and ball joints. Each has a unique number that corresponds to a specific vehicle make, model, year, and sometimes engine or trim level. Understanding this system is the first step in cross-referencing.
Why Cross-Reference with Ultra-Power?
Ultra-Power is a trusted aftermarket brand known for producing suspension parts that meet or exceed OEM specifications. Their components often offer comparable quality to dealership parts but at a lower price. Cross-referencing allows you to replace worn or broken suspension parts without paying a premium for the OEM brand. Plus, Ultra-Power parts are widely available through auto parts retailers and online catalogs. By matching the OEM number to an Ultra-Power part number, you gain access to a budget-friendly yet reliable solution.
How to Cross-Reference Suspension OEM Part Numbers to Ultra-Power
Step 1: Locate the OEM Part Number
Start by finding the OEM part number on the existing suspension component. Look for a series of letters and numbers molded into plastic parts, stamped onto metal brackets, or printed on a label. Common locations include the strut body, control arm, or tie rod end. If the part is too worn to read, check your vehicle’s service manual or use online OEM lookup tools by entering your VIN. Write down the entire number exactly as it appears—including dashes or spaces.
Step 2: Identify the Suspension Component Type
Not all suspension parts are interchangeable, so confirm what type of component you’re dealing with. Is it a complete strut assembly, a shock absorber, a lower control arm, or a ball joint? Each category has its own numbering system. Ultra-Power catalogs organize parts by vehicle and component type, so knowing the category narrows your search.
Step 3: Use Ultra-Power’s Lookup Tool or Catalog
Most auto parts retailers and Ultra-Power distributors offer an online cross-reference function. Enter the OEM part number into Ultra-Power’s search tool—often found on their website or via a parts store’s database. The tool will return matching Ultra-Power part numbers. If you don’t have online access, consult a printed catalog from your local parts store. Look for a section labeled “Cross Reference” or “OEM to Ultra-Power.”
Step 4: Verify Vehicle Fitment
Even if the part number matches, double-check fitment for your specific vehicle. Ultra-Power listings include application details such as make, model, year, and sometimes engine size or drive type. Confirm that the part is designed for your vehicle’s suspension configuration—for example, a loaded strut assembly for a 2015 Honda Civic LX 2.0L is different from one for a 2015 Honda Civic EX with 1.8L. Also verify the position (left vs. right) if applicable.
Step 5: Check Specifications
For critical components like shocks or control arms, compare physical dimensions, load ratings, and mounting points. The Ultra-Power part should have the same stroke length, spring seat height, and bushing sizes as the OEM part. If you’re unsure, measure the old part or consult a mechanic. Ultra-Power often publishes spec sheets; request one if needed.
Common Suspension Parts and Their OEM Number Formats
- Strut Assemblies: OEM numbers often start with letters like 51605, 51606, or 71401 (Honda). Ultra-Power equivalents use a similar structure but with a prefix like UP-.
- Control Arms: Numbers like 54500 or 54501 (Toyota) are common. Ultra-Power part numbers may include the vehicle platform.
- Tie Rod Ends: OEM numbers such as 45046 or 45047 translate to Ultra-Power units like TR-…
- Sway Bar Links: Often short codes like 48820 (Nissan) map to Ultra-Power’s SW… series.
- Ball Joints: Numbers like 43300 (GM) become UP-… in the catalog.
Always treat each number individually—different manufacturers use different formats. Never assume two similar-looking OEM numbers are interchangeable; they may vary by vehicle generation or option.
Tips for Accurate Cross-Referencing
- Write down the OEM number exactly as it appears – including letters, numbers, and any hyphens or spaces. Omitting a digit can lead to the wrong match.
- Use multiple sources – Check Ultra-Power’s official catalog and also independent parts store databases. If two sources agree on the cross-reference, it’s more reliable.
- Consult a mechanic – If you’re not 100% sure, ask a trusted repair shop. They often have experience with cross-referencing and can verify fitment.
- Watch out for supersessions – OEM manufacturers sometimes update part numbers. The original number may have been replaced by a newer one. Ultra-Power’s catalog may reflect the latest supersession, so your old number might cross to a different Ultra-Power part.
- Don’t rely solely on a photo – Even if the parts look identical, slight differences in bushing diameter or thread pitch can cause installation issues. Always match the part number.
Final Recommendation
Cross-referencing suspension OEM part numbers with Ultra-Power is a straightforward process when you follow these steps. Start by accurately locating the OEM number, use Ultra-Power’s lookup tool or a retail catalog, and always double-check fitment for your exact vehicle. Ultra-Power offers a wide range of suspension components that deliver reliable performance at a lower cost than dealer parts. For the best results, purchase from an authorized Ultra-Power distributor and keep the receipt for warranty purposes. If you encounter any doubts, contact Ultra-Power’s technical support with your OEM number and vehicle details—they can confirm the correct part. By taking these precautions, you’ll save money without compromising on quality or safety.
