Description
When only the strongest driveline solution will do, the Premier Tuning Group (PTG) Built Differential delivers unmatched reliability and performance for your Mercedes-AMG W204, W205, or W213 chassis. Designed for enthusiasts pushing the limits of their vehicle’s power output—or for those needing a bulletproof replacement for a damaged OEM unit—this is a complete high-performance differential upgrade with your choice of gear ratios and a Wavetrac® Limited Slip Differential (LSD).
Whether your factory diff suffered from worn gears or failed under high torque loads, the PTG Built Differential offers a fully rebuilt and reinforced solution with all-new internals. Every unit is built by PTG’s experienced motorsport engineers to ensure flawless integration, smooth operation, and track-tested durability.
As a bonus, this system comes with a TCU tune (722.9 or 725) specifically calibrated to your selected gear ratio for seamless performance and drivability.
