Someone on this site told me I could replace my tie rod hardware, and that the new parts would handle much better than the old parts. Are there any upgraded tie rod parts and/or pitman arm, drag link parts available aftermarket?

 

you are probably looking for a traction bar, a component of which would be the tie rods. it preloads the front lower control arms to help dampen wheel hop.

search for "traction bar" in the ef forum archives and you will find comparisons on which is the best to drop money on. they are expensive.

the only aftermarket radius rods i have seen were on some tuning shop's website from japan, and the whole add was in japanese and they were like $500 usd for a set, which would get you a whole traction bar and not just radius rods.

radius rods just help with toe though.. so they wont be much of a "upgrade" unless your front wheels are pointed like this: / \ .
