I found a good deal on new trd springs for first gen xb but checked the part numbers and found the xa and xb are 1 number apart and xb's are much cheaper than xa's, anyone know the difference and if the xb's will fit the xa

 

does anyone know the difference or why the part numbers are not the same

 

the XA has a lighter spring rate, you won't be happy with them on an XB

 

^^^ the phrase boing boing boing comes to mind.

 

from what i know theres no difference at all depending on the year

 

Mounting wise, there is no difference. Spring rates however are very different.

 

I have the xa the springs being different make sense what about the shock difference - what would the xb shock change being used on an xa

 

Not sure about that one roak. There might be a difference when it comes to rebound resistance and intert dampening. The xB shocks/struts may have a little more resistance both ways causing the ride to feel rough on an xA. Without the solid numbers on the two different shocks/struts, I can't be certain.

 

They might be different, but they will fit. I have the Springs/Struts/Shocks from My xB on my xA and it is fine, not as low, but there are reasons for that.
