Yea. Losi and TLR are going crazy right now. TLR hasent came out with any new things and discontinued most of their SCT and ST kits. 2wd buggy is outdated to today's standards a little.
The base slash (xl5) has steel adjustable links and full bearings. The ones that has plastic non adjustable links and bushings are the base xl5 bandit, rustler and stampede.
