About this part

Product Details

Manley Performance is well-known for making serious engine components for racing and high-performance builds. This set of Tour Lite I-Beam connecting rods is a prime example of their commitment to quality and performance. These rods are designed for Chevrolet small block engines and measure 5.700 inches in length, a common size for many performance applications. If you're building a high-revving or powerful street/strip engine, connecting rods are a critical part of the rotating assembly, and Manley's Pro Series rods are built to handle the stress.

These particular rods are forged from 4340 vacuum degassed steel alloy. This material is chosen for its strength and durability, making it well-suited for demanding engine conditions where stock rods might fail. The I-beam design is a popular choice for performance applications because it offers a good balance of strength and weight savings. Manley also offers these rods in different weight classes, and this set is part of their 'Tour Lite' offering, indicating a focus on reducing rotating mass for improved engine response. Some rods in the Pro Series line are NHRA Legal, which means they meet specific standards for certain racing classes, though you'll want to verify the NHRA legality for this specific part number if that's a concern for your build.

When installing connecting rods, it's crucial to ensure proper balancing of the entire rotating assembly – crankshaft, pistons, rings, wrist pins, and connecting rods. This set is designed to fit right into a Chevrolet small block engine, but it's always recommended to consult your engine builder or a service manual for precise installation procedures, including bearing clearances and torque specifications. This set includes the connecting rods needed for a V8 engine.
