4340 Chrome-Moly Connecting Rods
This is our unique single rib design E- 4340 chrome-moly rod. While the majority of our steel rods are manufactured from 4340 steel forgings, special applications that do not fit the dimensions of our forging are made from 4340 steel billet. These rods are available for import, domestic and vintage engines. Overall, the clean, windage-reducing configuration combined with the strength of the Pauter rod design, consistent high quality and excellent finish has proven to be extremely popular with racers in all venues. The result of our efforts can be seen in many decades of repeat satisfied customers.
Custom versus off-the-shelf thinking
Our usual policy as to in-stock and custom built connecting rods is a bit different from other manufacturers. We gear our production towards the custom, made-to-order end of the spectrum, stocking only a few “popular” sizes. From both the manufacturer’s as well as the customer’s point of view, this policy has its advantages. Even in identical situations, two different builders will often have differing ideas as to optimum rod specifications. Multiply this example by the myriad forms, classes, even sub-classes of racing out there, and custom parts in reality become the norm instead of the exception. We acknowledge this, and our rod program is geared to provide a high level of custom service as standard practice. We are CNC and CAD proficient, all tooling and production has been streamlined to handle one-offs as easily as multiple quantity orders. The upside is that any set of dimensional specs are OK, and turnaround on our chrome-moly rods is currently 5-6 weeks from the original processing of your order. On-shelf items are as stated above, usually limited to a minimum number of popular repeat sizes. Please be advised, all custom orders MUST be prepaid prior to production.
While we maintain an ever increasing list of part numbers for a wide variety of makes, actual applications for the same type of rod can vary greatly depending on the intended use; ranging from normally-aspirated, moderate horsepower to extreme-duty high-boost exotic fuel applications. Our shelf-stock parts are designed for the most commonly applied use of the part for that type of engine and does not imply a one-size-fits-all strategy. It is always recommended that you or your reseller contact our tech department prior to order to assure the parts will be the correct match for your application. This is particularly important for engine programs that are designed to make 2 or more times the base power of the factory engine.
PAUTER ALUMINUM CONNECTING RODS
Pauter Connecting Rods in Aluminum
Pauter aluminum rods are manufactured with the same personally involved racing background and enthusiasm that became the impetus for the development of our entire line of performance parts over the past five decades. As you know, Pauter 4340 chrome moly, as well as our titanium rods have been part of the made in the USA performance aftermarket since the late 1980’s. What you may not be aware of is the fact that in those early days, we also supplied a small contingent of engine builders with our own line of aluminum rods. However, for reasons of manufacturing capacity, we kept production of these parts to a minimum while concentrating on increasing our market share of our exclusive “Cross beam” steel and titanium rods, thus forcing their aluminum counterparts to take a necessary hiatus. Fast forward to 2012, with the addition of several high tech CNC machining centers, our production capacity has increased sufficiently to once again include aluminum to our current wide range of connecting rod applications.
During the lapse in production of our aluminum rod program very little had changed in actual physical appearance of these parts. However, the same cannot be said with regard to the latest materials deemed suitable for the ever-increasing performance demands realized over the same time period. The popular aluminum alloys previously incorporated by most manufacturers, including ourselves, consisted mainly of the tried and true 7075 and 2024 series but thanks to advances in the aero-space materials industry, new alloys have been developed that combine the lower temperature high strength qualities of 7075 with the 2024 alloy’s advantage of better maintaining its base strength at greater operating temperatures.
PAUTER TITANIUM CONNECTING RODS
Pauter Connecting Rods in Titanium
Similar to our chrome moly steel billet rods, our 6AL4V titanium rods are crafted from bar stock. Titanium rods differ from our steel rods in that they weigh considerably less for reduced rotating and reciprocating weight. On average, our titanium rods weigh 33% less than their steel counterpart. In a 6-cylinder (steel rod) engine, that is the weight equivalent of removing 2 (steel) rods from the complete rotating assembly. Typically, the big end of a steel rod weighs more than an entire titanium rod. The Pauter 6AL4V titanium connecting rod is available for most applications on a custom order basis. Due to the steps involved in manufacturing as well as customer demand, these rods are processed start to finish in 6-8 weeks.
Applied use of the part for many types of engines does not imply one-size-fits-all. While we maintain an ever increasing list of part numbers for a wide variety of makes, actual applications for the same type of rod can vary greatly depending on the intended use, ranging from normally-aspirated, moderate horsepower to extreme-duty high-boost exotic fuel applications. Our shelf-stock parts are designed to meet the most common performance needs. It is always recommended that either you, or perhaps your reseller, contact our technical department prior to order to assure the parts will be the correct match for your application. This is particularly important for engine programs that are designed to make 2 or more times the base power of the OEM factory engine.
