Pauter Rods Years of hands-on experience, working with rods of all shapes and materials, of all types of racing and racing-related abuse, with design failures (and successes), has resulted in a fairly comprehensive file on just what works - and what doesn't - on the subject of high performance Pauter connecting rods. From this body of knowledge Pauter Rods have selected and incorporated the elements into what it is we think a great rod should be. Right off, Pauter rod looks different, that's obvious, but for some not so obvious and very good reasons.

For starters, the simple Pauter beam design completely eliminates thin and non-uniform cross sections over the total length of the beam. This feature greatly improves resistance to crack-induced metal fatigue. In addition, the non-tapered profile of the Pauter rod beam helps to spread potentially harmful stress over a larger area, dispersing instead of concentrating these destructive loads. The design also efficiently places needed material in critical transitional areas, giving maximum support exactly where it is needed (such as directly under the wrist pin). The streamlined contour also provides subtle benefits in the form of windage reduction. The main beam rib itself continues around the wrist pin boss, perfectly integrating the beam to the pin boss, a small, but important contribution to overall structural unity. Pauter rods are indeed, different by design.
