I have neve heard good stuff about ACNCM products (I'm guess thats who makes them)...Actually, I had some of there bulkheads and didn't run the truck long enough to really put them to the test, but the ACNCM head I had for my TRX 2.5 SUCKED!
Hey those look good but for a set of all 8 arms you will be paying about $155
But for $165 you can buy each arm individualy from Gorillamaxx and I guarintee you they will look cooler and they are made for racing so i think no postive though that they are a little longer than the stock arms (as far as wheel base) check them out the set with shock towers and hinge pins goes for like 270 but just the arms if i am not mistaken goes for $165 check them out they are race inspired and so cool
