Yeah, they should screw into the RPM arms like it would a stock a-arm. Otherwise, you can certainly buy some nicer aftermarket pins- but be warned, the RPM arms are abit fatter than stock arms, so you may need to trim the arms in order to install the little C-clips / e-clips on both ends of the hingepin. Not a big problem, just something you need to be aware of. Have a look on ebay for 'e-maxx hinge pins', comes up with plenty of results.
