Forged H-Beam Connecting Rods

Integrated Engineering Forged Drop-In Connecting Rods provide a robust upgrade for VW and Audi EA888 Gen 1 & 2 TSI engines, addressing the limitations of factory components when increasing power output. These rods are forged from vacuum-drawn, two-piece 4340 chrome moly steel and feature an upgraded H-beam design for superior strength and durability, capable of supporting up to 700HP on 4-cylinder applications. The "drop-in" design utilizes a 21mm tapered wrist pin, specifically intended for use with stock 21mm tapered wrist pin pistons only, eliminating the need for modifications or machine work to the block. This allows for a faster and easier upgrade, with many builds potentially completed with the engine block still in the vehicle. Each rod set is individually computer-optimized for unique VW/Audi engine applications, honed in-house to tolerances within 250 millionths of an inch, and balanced to weights within +/- 1 gram for extreme reliability. Key technical specifications include a 144mm center-to-center length, 21.90mm big-end journal width, 50.60mm big-end journal diameter, and 3/8" x 1.5" UHL ARP 2000 rod bolts. The product FAQ clarifies that this connecting rod is not compatible with aftermarket pistons and recommends installing new connecting rod bearings at a minimum. Installation of bearing tangs should face the exhaust side of the engine. While the rods are delivered ready to install, other engine machine work like decking or boring may be required during a full rebuild. Professional installation and tuning are recommended for optimal performance and reliability. These connecting rods are compatible with a wide range of Audi and VW models equipped with EA888 Gen 1 & 2 TSI engines, including the A4 (2009-2015), A5 (2008-2015), Q5 (2008-2015), A6 (2012-2015), TT (2008-2015), A3 (2006-2013), Q3 (2011-2015), GTI (2006-2014), Jetta & Jetta GLI (2010-2014), Jetta SportWagen (2011-2014), CC (2009-2015), Passat (2006-2010), Eos (2006-2015), and Beetle (2011-2015). Engine codes include CCTA, CCZA, CCZB, CBF, CBFA, and CAEB. The product requires factory 21mm wrist pin tapered pistons.
