ARP takes the worry out of adding horsepower with the introduction of special rod bolts for Subaru 2.0L WRX and 2.5L WRX/STI applications. Made from proprietary ARP2000 material, they are nominally rated at 220,000psi tensile strength-a full 26 percent greater than the OEM Subaru connecting rod bolts.
EJ20 And EJ25 Valvesprings
With oval wire rod design, it's possible to reduce the overall height when compressed, making the length shorter when used with solid lifter conversions. This in turn helps raise the allowed camshaft lift up to 11mm. When used in conjunction with their high-profile camshafts, the results are easily noticed, even with the factory standard camshafts or any other high-profile aftermarket camshafts. Designed for use with high-lift camshafts.
