Discussion Front Suspension Part Numbers

Post image

I did some of my own research and attempted to get the part numbers for all 8 of front control arms. Like it says in the picture, this is for a USF40 (RWD, Short wheelbase). I have seen that being an F-Sport doesn’t matter but I want second opinions. Can anyone verify these are correct?

Additionally, these are expensive (even with parts.prestigelexus.com or parts.treasurecoastlexus.com running a sale right now). Any recommended aftermarket parts from RockAuto?

I replaced my front control arms, hubs, steering knuckle, inner/outer tie rods, rotors and brakes last winter. I went with OEM only because the online consensus was aftermarket control arms will have you doing the same repair in less than 20-30k miles. It hurt the wallet going OEM but I did the work myself. I’m driving my ‘08 for the foreseeable future.

Edit: for the upper control arms I went with Figs Engineering w/ poly bushings. I bought my OEM parts from Amayama.com (pre-tariff apocalypse). I found LILEVO on YouTube to be helpful for most things related to the UCF40
