Limited Slip Differential

The Guard Transmission 951 Pro is a limited-slip differential engineered to the industry standard for high-performance Porsche applications. Its construction includes a high-strength, hardened 4340 Chromoly billet body paired with a robust 8620 cover, ensuring exceptional durability under demanding conditions. This model comes standard equipped with 4 friction discs, with options to upgrade to 6 or 8 disc configurations for enhanced performance tuning. Guard Transmission LSDs are renowned for their strength and adjustability. The CNC billet bodies are unrivaled for their robustness, and the asymmetrical ramps, combined with proprietary clutches, allow for precise tunability to meet the specific needs of various drivers, from weekend track enthusiasts to professional race teams. Each LSD is configured for a single customer, taking into account their exact chassis, skill level, and power output, backed by two decades of Porsche-focused transmission experience. Specifically designed for the 951/944 models, the 951 Pro requires the oil pump drive gear to be purchased separately for proper installation and function. This unit exemplifies Guard Transmission's commitment to providing tailored solutions rather than a one-size-fits-all approach.
