Whiteline Lower Radius Arms

Post by JRWolff » Wed Jan 18, 2023 1:44 am

Hi All,
Has anyone tried the Whiteline Front Lower Radius Arms (WA386L and WA386R) on a 11-13 Caprice? They are listed for a G8, however, I think most of the front suspension is interchangeable between the G8 and Caprice. Looking for any feedback or results if you have tried these.

Thanks,

John

As a follow up, I contacted Whiteline and they confirmed fitment on the 11-13 Caprices. I held the Whiteline right side one against the factory one installed on my Caprice and also could not see any visual differences. So, it appears that all is good.

Just curious why GM would have different part numbers for the 08-09 G8 compared to the 11-13 Caprices:

Left G8 - 92253411 Caprice 92253413
Right G8 - 92253412 Caprice 92243414

Any insight is greatly appreciated.

Thanks,

John

FYI, I just found that the lower trailing arms (92253413, 92253414) for the Caprice are ALMOST identical to the G8 pieces. However when placed side-by-side the Caprice arms have a larger diameter tapered stud. Heavier duty, I suppose.

So, if i understand you correctly, the Whiteline parts for a G8 then will NOT fit a 2011-2013 Caprice?
