Show original supplier description
Crafted with precision, its internal gears are made from high-strength 9310 alloy steel, while the differential body is machined from a case-hardened steel billet. The product is designed for specific Porsche transmissions, including G50 variants, and is compatible with a range of models such as the 911, 930 Turbo, Carrera, 964, 993, 968, and certain 996 and 997 variants. Fitment details include a comprehensive list of Porsche vehicles from the 1970s through the early 2010s. Specific applications note requirements like manual transmissions and G50 transmission compatibility, ensuring precise integration. For example, the 930 Turbo (1989) requires the G50 transmission for this differential, and the 996 GT3 Coupe (2004-05) needs a 6-speed manual transmission and G50 compatibility. Similarly, the 993 Turbo Coupe (1996-97) requires the G50 transmission.
