yeah OFNA has an army of buggies the nice thing about that is that most of the parts are interchangeable. i found this out when i bought my hyper 7 from ebay, it came with three different arms. the rears are from somthing old and the fronts were new hyper 7 and old hyper 7. there were varying shock mount spots but overall it was no issue and functioned just fine. i ended up getting a complete set of arms just to make it even. My buddy has an ultra comp lx1 buggy and i compared his to mine...his has way more ground clearance then mine. If you're looking to build a truck, you might as well build it to tackle nasty terrain[>:]...hehe my iner savage 4.6 SS is comeing out.
