Show original supplier description
The NISMO GT Con-Rod Spec 2 (Part Number: 12100-RRR4B) is a performance-oriented connecting rod engineered for demanding engine applications. Constructed from high-strength SNCM439 nickel-molybdenum material and featuring an I-shape design, these rods provide exceptional durability and strength while maintaining a lightweight profile. The Spec 2 designation indicates a specific compression height requirement of 28mm for compatible pistons. These connecting rods are designed to work in conjunction with a NISMO GT Crankshaft and appropriate pistons to achieve an increased engine displacement of up to 2771cc, a significant enhancement over the OEM capacity. The center-to-center length of these rods is 121.5mm. This product is compatible with various Nissan Skyline GT-R models (BCNR33, BNR32, BNR34) and Stagea WGNC34 equipped with the RB26DETT engine. Specific model year ranges include Nissan Skyline GT-R BCNR33 from 01/1995 to 05/1998, BNR32 from 08/1989 to 12/1994, and BNR34 from 01/1999 to 08/2002. It is also compatible with Nissan Stagea WGNC34 RB26DETT from 11/1997 to 09/2001. It is important to note that compatibility information is provided by the manufacturer for JDM (Japanese Domestic Market) vehicles only, and fitment is not guaranteed. Buyers are advised to conduct their own research before purchase. After-sale support does not extend to installation assistance.
