INFO
This aftermarket set contains eight polished metal floating-pin connecting rods for the documented GM Gen IV V8 rotating-assembly applications. The product record covers selected Chevrolet Avalanche and Silverado 1500, GMC Sierra 1500, and GMC Yukon configurations using the stated 5.3L, 6.0L, or 6.2L engine and matching floating-pin design. Recorded interchange references include 12577583, 12617570, 12569639, 12607475, 12649190, and 12604629. These numbers identify compatible replacement references and do not make this set a genuine General Motors product.
The package contains eight floating-pin connecting rods total. Pistons, piston pins, pin retainers, piston rings, rod bearings, main bearings, crankshaft, gaskets, fluids, and additional rotating-assembly parts are not included. The floating-pin configuration is a product-defining feature and should not be treated as interchangeable with a press-fit rod arrangement. The eight-piece quantity is intended for the recorded V8 package and distinguishes this SKU from single-rod listings and six-piece V6 sets. This is an aftermarket engine rotating-assembly component set, not a complete rebuild kit, short block, or assembled engine. Only the pieces shown and identified in the package record are included.
Features
- Eight floating-pin connecting rods in one package.

- Floating-pin configuration for the matching rotating assembly.
- Polished metal construction.
