After several days of PM's between Brian at Posi and myself I decided to pull the trigger on Upper Control Arms with the HD bracket and the Lower Control Arms. Everything was made by Metco and made in America! My initial concerns NVH turned out to be for nothing! I'm truely impressed with the quality of these pieces and the performance I gained with them. I have no wheelhop whatsoever and alot more traction. I picked up zero vibration, zero harshness and a slight increase in rearend gear noise only on deceleration when downshifting. The increase in rearend gear noise is very slight and only noticeable if the radio is off and you're listening for it. I'm very happy with the results. If anyone is thinking about this upgrade, don't hestitate! Metco makes some quality stuff and Posi is excellent to deal with.
