The next step in the Compstar line up. All the quality, reliability and workmanship you have relied upon for years from the Compstar line up is taken to the Xtreme. Specifically designed for power adder and diesel applications. The Compstar Xtreme utilizes the same proven 4340 material and ARP L19 fasteners. Strength is added by thickening up the flanges of the H beam and a reduced depth of cut towards the center of the rod. Then non-essential weight is taken out of the beam to help keep the overall weight of this rod in check.
