BoostLine Connecting Rods are your best option for any high horsepower Subaru EJ engine build. Track proven in Mark Jager's 900hp+ Time Attack record holding Subaru. Our engineering team created this new, patented 3-pocket design specifically for demanding turbocharged applications. BoostLine Connecting Rods provide 60% more bending strength compared to common H-beam rods! Each rod is designed, finished and inspected in the USA and includes a detailed inspection report generated on our Zeiss Coordinate Measuring Machine (CMM). Machined from premium 4340 forged steel. High quality ARP 2000 Bolts included.
BoostLine connecting rods for highly boosted Subaru EJ20 and EJ25 engines were launched a little over three years ago. These unique, lightweight rods can handle upwards of 1,000-horsepower in 4-cylinder applications and are a substantially more durable alternative to aluminum drag racing rods.
Part Number: SB5137-905
Because of the high cylinder pressures associated with big boost, BoostLine engineers focused on making the rod more resistant to bending under massive power loads.
