So spear throwing useful items and feats

[Cheesy bucket]

I have this character I'm working on they use heavy armor and throw two-handed spears
They are a soul knife so they can make more spears and using class skills the range is at 20ft at level 4 but I want the range to be a bit more so are their some feats or wonderful items to help out

A trait can help you here. Additional Traits can help you there if you want a feat specifically I guess. Two-Handed Thrower is the obvious specific feat you want of course.

A belt of mighty hurling is the obvious item to go for.
