What size are RSX type S axles?
The RSX Type S does not have a single, fixed axle size. Front CV axles for this car vary by year and by side (left vs. right). The DC5-era RSX Type S uses a 5x114.3 wheel bolt pattern, but the exact axle length and joint dimensions depend on the exact production year and specification. For a precise fit, you should reference the OEM part numbers for your specific car.
To understand what this means in practice, consider that Acura’s RSX Type S—produced from 2002 to 2006—came with front-wheel drive and a two-axle drivetrain that mates the transaxle to the front wheels. Across those years, there were minor revisions, and the left and right axles are not guaranteed to be identical in every respect. This article explains the key points and provides a clear method to determine the exact size you need for repairs, replacements, or swaps.
Key facts about RSX Type S axles
Before diving into measurement and parts lookup, here are the essential facts you should know.
- The RSX Type S uses a 5x114.3 mm (5x4.5 in) wheel bolt pattern, a common standard among many Honda/Acura platforms of its era.
- The car is front-wheel drive and uses front CV axles to connect the transaxle to the hubs; there are distinct left and right axles, and the sizes can differ by year and configuration.
- Axle size is not universal across all DC5 RSX Type S models. Minor revisions between early (2002–2004) and later (2005–2006) production can affect the exact length and joint dimensions.
- OEM part numbers provide the definitive reference for fitment. When replacing, you should match the axle part numbers to your exact year and transmission specification (and, if possible, your VIN).
In short, while the wheel mounting is standardized, the axial length and joint details are year- and side-specific. Verifying with OEM catalogs or a parts specialist is the most reliable way to ensure a correct fit.
How to determine the exact RSX Type S axle size for your car
Follow these steps to identify the precise axle size you need for repairs or replacements.
- Identify your exact year and trim: RSX Type S models were produced from 2002 to 2006, with manuals only for the Type S; confirm your year and whether any factory revisions were applied to your car.
- Look up OEM axle part numbers for your car: use the Honda/Acura parts catalog or a trusted dealer portal and search for the left and right front axle assemblies for your specific year and transmission. Note the part numbers for both sides.
- Measure your current axles if you must replace immediately: with the vehicle safely supported, measure the overall length from the inner CV joint housing (at the transaxle end) to the outer CV joint housing (at the wheel end). Also note any differences in inner vs. outer joint diameter or spline count if you can access that information from the existing part.
- Compare your measurements to the OEM specifications and aftermarket options: when shopping, look for axles advertised to fit the exact RSX Type S year and side; many aftermarket suppliers list compatibility by year, not just by model.
- Verify CV joint and spline compatibility if you are swapping to a different setup: ensure the inner and outer joint spline counts and diameters match your transmission output shaft and wheel hub interfaces, respectively.
Aftermarket and remanufactured axles are available in different lengths and joint configurations. Always double-check the exact fitment for your vehicle and consult the parts diagram or a professional if you’re unsure.
Common questions about RSX Type S axles
Here are a few quick considerations people often have when dealing with RSX Type S axles.
- Are left and right axles interchangeable on the RSX Type S? Not guaranteed. Although some aftermarket options may claim interchangeability, the lengths and joint configurations can differ between sides and across production years. Always verify with the exact part number.
- Can I use a non-OEM axle? Yes, but you must ensure the length and joint specifications match your car’s year and side. Incorrect length or joint size can cause rubbing, boot wear, or CV joint failure.
- Does the bolt pattern affect the axle size? The bolt pattern is separate from axle length or joint size. The RSX Type S uses 5x114.3 for wheel attachment, which does influence compatible wheel and hub spacing but not the CV joint dimensions themselves.
Summary
There is no single “one-size-fits-all” answer for RSX Type S axles. The front CV axles are year- and side-specific, with a standard 5x114.3 bolt pattern but varying overall length and joint configurations depending on production year and whether the left or right axle is involved. To ensure a correct fit, consult OEM parts diagrams for your exact year, or have a parts professional verify the correct axle part numbers for your RSX Type S. With precise part numbers or measured specifications, you can confidently replace or upgrade your axles without fitment issues.
