Second Hand Mercedes-Benz SL Axle

Both years fall within the R230 generation (2001–2012), so there is a reasonable chance of compatibility, but the R230 did receive updates across its production run and engine variants can influence axle specifications. Confirm the exact part numbers with the breaker against both registrations before buying.

The R230 SL was facelifted in 2008, and while the basic platform carried over, running gear components can differ across that boundary due to revised suspension and brake specifications introduced at the time. Name both the donor and recipient registration to your breaker so they can check the part numbers match before you commit.

No — the R129 (1989–2001) and R230 (2001–2012) are entirely different generations with different subframes, suspension geometry, and axle designs, so the parts are not interchangeable. You need to source an axle specifically from an R230 donor vehicle.

Yes, engine size matters here — larger-engined SL variants such as the SL55 AMG and SL65 AMG carry heavier, more powerful drivetrains and typically use heavier-duty rear axle components compared to the SL350 or SL500. Always give the breaker your exact engine variant alongside your registration to ensure you get the correct spec axle.

Trim level in itself does not affect axle fitment, but engine size does, and the SL350 and SL500 are different engine variants that can carry different axle specifications to cope with the extra power and torque of the larger unit. Quote your exact model designation and registration to the breaker rather than just the trim name to be sure.

The R231 ran from 2012 onwards as the successor to the R230, and parts from within the same generation are more likely to be compatible than across generations, but mid-generation engineering revisions mean fitment across different production years is not guaranteed. Confirm against your specific registration with the breaker before purchasing.
