V8 Connecting Rods — LS, Coyote, Hemi & SBC

V8 Connecting Rods — LS, Coyote, Hemi & SBC

Eight-cylinder connecting rods serve the most popular domestic V8 platforms in the performance aftermarket, including GM's LS and LT families, Ford's Coyote and Boss 302, Chrysler's Hemi, and the classic small-block Chevy and small-block Ford families. Upgrading connecting rods is essential in any V8 build targeting sustained power output beyond what OEM powdered-metal rods can survive.

Popular Upgrades

H-beam 4340 connecting rod sets for the GM LS1 through LS9 family and LT1 and LT4 are the most popular V8 rod upgrades, supporting builds from 500 horsepower street cars to 2,000-plus horsepower drag cars. Forged small-block Chevy and small-block Ford rod sets have a deep catalog heritage dating back decades, with options from multiple manufacturers at various price points. I-beam titanium rods are used in naturally aspirated race LS and Coyote applications targeting maximum RPM on nitrous or high compression.

What rod length do I need for my LS engine?

LS rod length depends on the specific engine variant. The LS1, LS2, and LS6 use a 6.098-inch rod, the LS3 and L99 use a 6.066-inch rod, and the LS7 uses a longer 6.066-inch rod with a different piston pin height. Always confirm the rod length and pin diameter for your specific LS variant before purchasing a set, as differences in rod length affect piston deck height and compression ratio.

Do I need to balance a V8 after installing new connecting rods?

Yes. An engine balance is strongly recommended any time the reciprocating assembly is changed in a V8. Aftermarket connecting rods are manufactured to tight weight tolerances, but sets should be weighed and matched within the specified gram tolerance. A professional engine balancer will correct any remaining imbalance across the full rotating and reciprocating assembly to prevent vibration at high RPM.
