Description
This Pro-H connecting rod configuration is listed for Porsche 997 Cup under SKU CRLSCR9273-6. Supplied as a set of 6, it is the Pro-H 22 mm Pin 3/8 in CARR Bolt version shown in this listing.
For a Porsche build, verify the engine generation and turbo or non-turbo specification, then compare pin size, rod length, and big-end width. A chassis number or displacement alone may not identify the correct internal engine configuration.
Pro-H identifies Carrillo's H-beam design family. Carrillo describes a steel-rod manufacturing process based on forgings, dimensional inspection, and shot peening. The relevant purchasing distinction remains this rod's specific geometry and fastener configuration.
The listed CARR fasteners belong to Carrillo's Multiphase bolt family. Identify the actual bolt markings and follow the corresponding installation specification; bolt diameter alone does not define the correct preload procedure.

Fitment and Assembly
Match the specified pin diameter to the piston and verify pin-end width and final running clearance; equal nominal diameters do not establish the required finished clearance. Check bearing fit, rod side clearance, and clearance to the block, crankshaft, and pistons during mock-up. Use the supplied specification card and the exact bolt installation instructions for final assembly.
