H-Beam Forged Connecting Rods for VW Golf, Passat, Corrado – 1.8L & 2.0L 16V KR / PL / 9A – 144 mm – 4320 Steel
These high-strength H-beam forged connecting rods are designed for performance-focused builds and racing applications based on VW’s iconic 16V KR, PL, and 9A engines. They provide maximum strength, fatigue resistance, and reliability under high-RPM and forced induction setups.
Made from premium 4320 chrome-moly steel and precision-forged, these rods feature a shot-peened surface to increase structural integrity and prevent microcracking. An integrated oiling hole in the small end improves pin lubrication under extreme engine loads.
With a 144 mm center-to-center length and 20 mm wrist pin bore, these rods are dimensionally compatible with OEM specs – allowing easy drop-in replacement with no modification needed. Their tight ±1.5 g weight tolerance ensures optimal rotational balance and smoother engine operation.
The set includes high-strength rod bolts suitable for high-RPM use, offering secure clamping under combustion pressure. This rod kit is built for engines producing up to 600–700 HP, depending on your setup and tuning.
