Minor point of clarification, Currie Enterprises split into two companies with Ray and Charlie taking Currie with the axle side and John taking the suspension side as Rock Jock.Savvy doesn't make the joints. RockJock does (well, Currie Enterprises). Savvy buys a RH and LH threaded JJ body and some Aluminum. They thread the aluminum, screw the JJ's in and Sell em.
