View Full Version : ST185 Front Strut Replacements

Question on ST185 front strut replacements.

The original ST185 front strut part numbers were 48510-20660 & 48520-20660.

Most other 5th Gen Celica original front strut part numbers were 48510-20680 & 48520-20680.

Some 5th Gen Celica GT-S original front strut part numbers were 48510-20750 & 48520-20750.

Today, all of the above original front strut part numbers supersede to 48510-20751 & 48520-20751.

I'm suspecting there was a reason for unique original part numbers for these 5th Gen Celica's. Now the superseded part number for front struts are the same across the entire 5th Gen Celica line.

Anyone know what was unique about the original part numbers? And where the superseded part number fits in with the originals? (i.e.; if the valving was the only thing different across the original part numbers, how does the current part number valving compare with the originals, or which version is the currently available front strut valved closest to)?

It also appears all aftermarket cartridges available today are the same cartridges across the entire 5th Gen line (same KYB or Monroe cartridges for front struts, regardless if the 5th Gen Celica was an ST, GT, GT-S or All-Trac).

I was contemplating putting in new OEM front struts on an ST185, but not sure if the now common part number is the same strut that originally came with it. Any advice?

Get Koni Yellows, worth it.

Koni yellow what? Strut assemblies or inserts? Do you have any part numbers? If strut assemblies, are these the adjustable ones?

Yes, the adjustable inserts. I don't have the part numbers handy.
