BoostLine CH6200-927 Forged 4340 I-Beam Connecting Rods for Dodge Gen 3 HEMI

Vehicle Fitment

• Dodge/Chrysler/Jeep Gen 3 HEMI engine platform - stroker applications using a crankshaft with 2.126" rod journals and 6.200" center-to-center rod length
• Common stroker builds: 392ci, 410ci, 426ci, and similar displacement combinations using aftermarket stroker crankshafts in 5.7L, 6.1L, 6.2L, and 6.4L HEMI blocks

Fitment Notes

• This is a 6.200" center-to-center connecting rod with a 2.126" big-end journal bore - it is designed for stroker crankshafts, NOT stock-stroke applications
• The stock Gen 3 HEMI rod length is 6.125" with a 2.100" journal - for stock-stroke builds, see BoostLine CH6125-927
• Requires a 0.927" wrist pin diameter piston
• Engine builder must verify crankshaft rod journal diameter, piston pin size, and block clearances before ordering
• Designed for high-boost, supercharged, and nitrous-assisted engine combinations

Features

• Patented 3-pocket I-beam design engineered specifically for forced-induction and nitrous applications
• Forged from premium 4340 chromoly steel for maximum strength under extreme cylinder pressures
• 60% improvement in bending strength compared to common H-beam connecting rod designs
• 20% reduction in tensile stress compared to H-beam designs for improved fatigue life
• Dramatically improved big-end stability under high tensile loads at elevated RPM
• High-quality Ampco bronze bushing material in the small end for superior wrist pin bearing performance
• Industry-leading ARP 2000 fasteners included as standard (ARP 625+ upgrade available separately)
• Each rod individually inspected on aerospace-grade CMM equipment with inspection report included
• Designed and finish-machined in the USA in Mentor, Ohio
• Rated up to 2,000 horsepower in 8-cylinder applications

Product Description

The BoostLine CH6200-927 Connecting Rod Set is purpose-built for high-horsepower Gen 3 HEMI stroker engine combinations running forced induction or nitrous oxide. With a 6.200-inch center-to-center length and a 2.126-inch big-end journal bore, these rods are designed for use with aftermarket stroker crankshafts - not the stock 6.125-inch rod length or 2.100-inch journal found in factory 5.7L, 6.1L, 6.2L, and 6.4L HEMI engines. The patented 3-pocket I-beam design delivers 60 percent more bending strength and 20 percent less tensile stress than conventional H-beam rods, making them ideal for the extreme cylinder pressures generated by turbocharged, supercharged, and nitrous-fed combinations.

Each rod is forged from premium 4340 chromoly steel and finish-machined at BoostLine's facility in Mentor, Ohio. The small end features a high-quality Ampco bronze bushing with pin clearance set between 0.0009 and 0.0011 inches, allowing engine builders to custom-fit the wrist pin specification. Industry-leading ARP 2000 fasteners rated at 220,000 psi are included as standard hardware, with an optional upgrade to ARP 625+ Custom Age bolts rated at 260,000 to 280,000 psi available for the most extreme builds. The 3-pocket body design combines the low rotating mass advantages of an I-beam with the big-end stability traditionally associated with H-beam rods, resulting in a connecting rod that excels under the high RPM and cylinder pressure demands of modern boosted HEMI engines.

BoostLine rates these rods at up to 2,000 horsepower in 8-cylinder applications, making them suitable for the most aggressive street and race HEMI builds. Every rod in the set is individually inspected using aerospace-grade coordinate measuring machine equipment, and each set ships with detailed inspection reports documenting critical dimensions to 0.0001-inch precision. Rods are vacuum-wrapped for corrosion protection and separated by thick foam inserts to prevent shipping damage. Engine builders should verify crankshaft rod journal diameter, piston pin size, and block clearances before ordering to ensure correct fitment in their specific stroker combination.
