*click here for further technical information on M2000 material. The result of our efforts can be seen in many decades of repeat satisfied customers. One rod manufacturer said they are now making custom rods for pins as small as 0.787? Level 2 profiles are for individuals that require more power and an extended rpm range. The rods are balanced end over end into matched engine sets and are 100% magnaflux crack detected prior to final inspection by CMM in our temperature controlled inspection department. 浙公网安备 33010002000092号 Please see information specific to your CID group in the more detailed product description below. This products quality exceeds all known available property balances for currently manufactured connecting rods. 0000063578 00000 n
One application that is hot right now for custom rod manufacturers is diesels. 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. These camshafts work well with four-speed manual transmission. 100% SATISFACTION. This leaves more metal around the wrist pin for added high rpm strength because the small end of the rod does not have to be drilled out to accept a bushing. 0000070644 00000 n
GRP connecting rods, a world leader in manufacturing billet aluminum and billet titanium connecting rods, is celebrating its 17th year in Denver, Colorado. But for a high torque, high load motor with a limited rpm range, steel rods would probably be better. But in hig- revving engines, increased tensile strength is an absolute must for the rods to survive at high rpm. Those who still use domestic-made forgings say some of the offshore product identified as 4340 steel does not meet AISI 4340 standards. Metal powder is pressed into a mold and heated to high … Aftermarket torque converter with slightly higher stall speed is recommended because stock factory converters do not allow the engine to provide adequate idle speed and off idle performance. 0000002477 00000 n

We can make any model as H,I,X-beam style, even customer design. Titanium Connecting Rods Mortorcycle (4 Cycle) Part No. I-Beams can be just as strong as H-Beams, but H-Beams can often handle higher compressive loads than I-Beams with less overall weight. Intended for stock or near-stock engines and drive trains, 8.5:1 compression, 2.70 to 3.25 ring and pinion, automatic transmission with stock converter or four-speed manual transmission. To make matters worse, there has also been a reported epidemic of knock-off products being sold as brand name connecting rods. 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.

This allows the thickness and cross-sectional area of the rod to be reduced so the rod can be 10 to 20% lighter than a comparable rod made of 4340 steel. Because of this, some ProStock racers who have been using aluminum rods have switched back to steel rods. 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. Most high dollar steel performance rods are often shot peened and/or cryogenically treated (frozen to minus 300 degrees F in a nitrogen bath) to alter the metallurgy of the grain structure, and to relieve internal stresses for better durability. ProStock racers may replace the rods after 20 or 30 runs. Shop the latest Engine Builder merchandise. Cylinder head modifications would be beneficial.
These grinds exhibit strong mid-range to top end torque and horsepower. There’s no bushing to replace so the small end has to be drilled out to accept a larger diameter pin, which means replacing the pistons, or drilling out the pin holes in the pistons to accept a larger (a probably heavier) pin. 38 57

The caps are usually cracked, which saves time and additional machining. If the item could be repaired by some small replacing parts,we could offer these parts to you freely. Category: Engine. These camshafts provide excellent low end and mid-range power for spirited street, off road driving and mild marine applications. Please be Aware That This May Not Work for Older Computers. It also benefits by maintaining plastic elongation and has core hardness up to 59 Rockwell C. Many steels at this strength level are not suitable for connecting rods due to their high notch sensitivity particularly in the thread region. These rods represent the perfect balance between weight and strength. There is no pat formula for rod ratios that work in every engine or every application.

Watch out for counterfeit bolts that do not meet strength specifications due to low quality alloys or improper heat-treating. With or without pin bushings is another decision to consider. A longer rod that causes the piston to sit a few degrees longer at TDC on the compression stroke also does the same thing on the exhaust stroke and that may actually cost you some power.

A set of quality steel rods will cost more than a set of aluminum rods up front (say $900 to $1,600 depending on the brand and quality, though some sell for as little as $500 to $600 a set). During the lapse in production of our aluminum rod program very little had changed in actual physical appearance of these parts.
