1990 XT fork springs
 

I bought some Progressive springs off of eBay which were listed to fit the 84-90 models. I got the 11-1141 model springs but Progressive lists that the 90 takes the 11-1506 spring which is 1mm smaller in diameter and softer. Looking on other sites it says I have the right spring, and other sites say that the 1506 only fits the 91-94??

Does anyone know if the springs I have will fit my 1990 or do I have to send them back?

You have 3TB? Then i would think the one marked as 91-95 is correct.
