RE: Aluminum and Plastic meet . .. .
Just keep a stock of the standard ones spare, the RPM ones are too bendy, the handling goes all squiffy, and you dont want ally ones cos they'll either bend, or transfer the stresses further into the truck and break something else, ive got ally knuckles on mine and thats all it needs for me, i havent broken any tie rods yet so i cant comment on those.
