FJ Rear Spring Part Numbers

[Brilliant]

Anyone know the difference between these rear spring OE part numbers:

2010 - 4x4 Rear Spring - 48231-35420
07'-09' 4x4 Rear Spring - 48231-35321

2010 - 4x2 Rear Spring - 48231-35430
07'-09' 4x2 Rear Spring - 48231-35331

I've heard that 4x2 sits a bit lower, so not too interested in those, but anyone know what the change was in 2010 to the 4x4 springs?

edit: changes like ride height, spring rate, etc

thanks
