Eagle H-Beam Subaru - EJ20 - EJ25 - 130.5 - Extreme Duty Connecting Rods (CRS5137SXD)

Eagle's Subaru connecting rods are crafted from high - quality 4340 steel. They go through a series of strict tests including x - raying, magnafluxing, sonic testing, and shot - peening to guarantee top - notch quality and strength. These rods come in weight - matched sets, with each set having a weight difference of within +/- 1 gram from end to end. The STI connecting rods are forged in two pieces in China and then sent to the US for final machining and testing. This process results in a cost - effective yet durable and precise rod. The EJ257 STI rods are equipped with ARP 3/8in 2000 rod bolts, which can handle high power and boost. The rod length is 5.137 inches. Compatible with EJ205, EJ255, and EJ257 engines. Part Number: CRS5137SXD.

Using these Eagle connecting rods is straightforward. First, make sure your Subaru EJ20 or EJ25 engine is properly prepared and cleaned before installation. Carefully follow the engine's service manual for the correct installation procedure. When handling the rods, be gentle to avoid any scratches or damages. Since these rods are weight - matched, keep the sets together during installation. Make sure to tighten the ARP 3/8in 2000 rod bolts to the specified torque to ensure optimal performance. For maintenance, regularly check the engine oil level and quality. Clean oil helps to keep the rods lubricated and in good condition. Inspect the rods periodically for any signs of wear or damage. If you notice any issues, replace the rods promptly. Also, avoid over - revving the engine to prevent unnecessary stress on the connecting rods.
