JConcepts titanium 5.5 x 6mm ball studs
A sought-after piece in the RC world is the 5.5 x 6mm ball-ends which seemingly attach to just about every corner of the Team Associated line of vehicles and JConcepts Regulator behind axle steering assembly. Previously, the kit versions were very heavy steel items which is a lot of unnecessary weight. With the JConcepts Titanium pieces, the application is smooth and simple with a 2mm wrench while the lightweight material screws together very easily.
