Summit Racing™ Trapezoidal Tech Connecting Rods

Summit Racing™ offers trapezoidal tech connecting rods for a variety of applications, including many Chevrolet small block engines from 1997 and up. These replacements are high-strength 4340 forged steel rods designed for maximum-performance LS engines, featuring a unique trapezoidal small-end design to support high boost and high RPM (up to 7,500+ rpm) while reducing weight. They're engineered to be part of a matched system with specific pistons, optimizing rod-to-wrist pin strength. Order the set recommended for your vehicle.

Key details:

* Trapezoidal small end: The small-end tapers to match the wrist pin, supporting it with minimal side clearance for increased shear strength
* Reduced rotating mass: This design allows for a shorter, stiffer, and lighter wrist pin, which reduces stress on the bearings and crankshaft
* High horsepower capability: Built for high-boost drag or street applications, often rated to handle over 1,200 hp
* 4340 forged steel: Built for maximum strength, usually with H-beam construction and shot-peened to remove stress risers
* High-end hardware: Typically equipped with ARP 2000 7/16 in. rod bolts capable of handling high tensile loads
* Precision Finishing: Bores are finished to +/- .0001 in. tolerances and sets are balanced to +/- 1 gram per end.
* These rods are typically part of the Summit Racing™ Pro LS or Pro LST lines, specifically tailored for GM LS engines, and require specialized pistons
