I need to replace my bushings in my traction arm / struts and I got into a rabbit hole thinking that the Supra arm could be swapped in, but it turns out the bushing design is completely different.

The Supra P/N is 48780-14030 and the Lexus P/N is 48780-24040. They are the same price from the dealers, but the Supra bushings stick out about 1/4" on each side, but the Lexus bushing is flat with the face.

I wanted to originally find a poly bushing but Energy only makes one for the Supra, Whiteline does not make one and Prothane does not make one either. You can buy an OEM Lexus bushing for about $50 (48725-24080) but I'd like to do poly.

I THINK Superpro sells one SPF2785K, but I'm not 100% it's for the correct arm?

Any ideas?

 

They are not the same length anyway are they?

 

Hmm, well, I guess just assume they are incompatible - now I need to find the correct flat face poly bushing for the SC.

 

From what I remember the sc arm is longer than the Supra. It’s been a while though.

 

Well, the Supra x-over thread says they are the same, but it's unclear how they think it's the same. Maybe the length is the same but the bushing width is not.

Prothane makes a complete rear end kit for our cars. I've bought a few over the years to grab 1 or 2 bushing out of them. I'll check if I have traction rod bushings this weekend. If you're local, you can have them if I find them.

 

The bushing width isn't the same, but the bolt sleeve width is the same on both arms. If you notice on the SC arm the bolt sleeve is wider than the bushing. This gives the bushing more flex making it more comfortable for the Lexus.
