Toyota OE shocks for a lowered 510

[SKYBLEW]

I found these NOS shocks yesterday, labeled 48531-35820.

 

Free lenght is 21.0", the valving, feels good, pretty heavy, I measured my old shocks at 22" FL, plenty of compression and rebound, gas charge still working, I calculated the working height to be about 18.0".

 

On-line research shows a close part number, not exact, belongs to the Corolla family, probably the EA86.

 

I'm sure their fine to work with my genuine BRE rear springs, just wondering if the community has seen these shocks before? 

 

Secondly I also picked up 2 48521-35880 shocks, waaay too short for our rear application, free lenght of 13.5" which makes a working lenght probably 9.0"

 

Lastly, how can I share images off my phone? I only see insert from URL available.

You can post the image to a photo sharing web site, like imgur.com. Then add the photo URL to the reply

imgur.com does not require an account, it will ask you to create one, but ignore that and upload the photo without creating an account

 

After you have made 26(?) posts then Ratsun allows direct photo uploads

Corolla has direct-acting shocks. The 510 has leveraged shocks, about 2:1 so presumably the shock valving will be much heavier compared to Corolla. With BRE springs, you might want even heavier valving again

 

That being said, they probably will be much better than worn-out shocks

 

 

By "free length" do you mean compressed length or extended length?
