JDY Audi 2.5TFSI EVO 300M Drag Connecting Rods
JDY Performance introduces the 300M Heavy-Duty Connecting Rods — a significant upgrade over traditional 4340 steel rods — specifically developed for high-output 2.5L TFSI EA855 engines (chain-driven). Designed to thrive under the intense conditions of extreme performance builds, these i-beam rods are rated up to 300 HP per cylinder , making them the go-to solution for enthusiasts chasing Anyturbo at 76mm or higher power levels. Why 300M over 4340?
While 4340 steel is a standard for performance applications, it falls short in durability when exposed to the elevated cylinder pressures and high torque abuse seen in builds pushing beyond 1 15 0 wheel HP. 300M alloy steel , originally developed for aerospace and motorsport use, offers:
Higher tensile strength
Superior fatigue resistance
Better performance in extreme temperatures
This means better reliability , less chance of rod failure , and peace of mind when pushing the limits. Other than the material superior , JDY 300M Drag rods offers :
Thickened I-Beam Design
Reinforced structure for increased rigidity and strength, crucial for high boost and high RPM stability.
Deep-Drilled Oil Tunnel
Allows continuous oil flow between the piston pin and rod bearing — maximizing lubrication and minimizing wear.
Dual Oil Grooves
Oil groove in side the small end of the connecting rods, provides extra lubriaction on the hard working wrist pins.
Grooved big-end for optimized crankshaft lubrication
High-Grade Bolts Included
ARP 2000 3/8" bolts (standard)
ARP Age 625 (optional upgrade for max durability under ultra-high boost)
Fully Machined and Balanced
Every rod is precisely balanced, pin end-angled, and QC-checked for optimal engine harmonics.
