2Pcs Coolant Line Skid Plate Protection Guards for Model 3/Highland Lower Chassis Coolant Pipe Protection Cover for Model 3 Highland Accessories 2017-2023.10+ (Powder Coated Carbon Steel)

First, I just want to warn/inform that none of these parts are replacements for what OP is talking about, OPs part is rearward of the rear aero cover between the aero cover and the rear bumper. These parts are still probably a good thing to swap out even if your plastic ones are not cracked yet…. I’m not 100% certain on this. But i’m pretty confident that there is only one factory making these aluminum ones: Front $124: https://a.co/d/06TokUhf Rear $121: https://a.co/d/0ftwfe0F And these i’m not sure about but it’s what i got for coolant line protectors $45: https://a.co/d/0f0sSXTb

I just figured carbon steel was better for protecting the coolant lines and aluminum was better for the skid plate (given its flexing and it being naturally corrosion resistant over steel since its likelyto get way more scratches).

But I wanted a single piece figuring its stronger. I went with aluminum for the skidplatd figuring flexing was more important and carbon steel for the coolant line figuring overall strength was more important there.
