Taylor Race Engineering Mk3 Differential: Unleash Peak FSAE Performance

The new Mk3 Differential is engineered to deliver an unparalleled competitive edge for your Formula SAE team. This isn't just a differential; it's a meticulously crafted system designed to optimize your car's handling, acceleration, and reliability on track.  The lightest version of the fully adjustable diff is 7.1 lbs (3.2 kg) for a complete system ready to install (includes bearings, tripod housings, and sprocket flange).  

Key Features & Advantages:

• Ultimate Tunability: Experience dynamic on-track tuning with TRE's new patent-pending external preload adjustability. Fine-tune your differential's behavior in minutes to optimize cornering, stability, and acceleration for any track condition or driver preference, all without disassembly.
• Adaptable Locking Behavior: Further refine your setup by easily swapping between our 3 different helical gearsets. Each set creates distinct locking characteristics, analogous to adjusting ramp angles on a clutch-type diff, allowing you to perfectly match your differential's response to your car and track.
• Revolutionary Fluid Tuning: Unlock maximum drive with our custom-blended non-Newtonian shear-thickening fluids. This advanced fluid dynamically increases locking under high shear rates (such as inside wheel lift), providing progressive, increased drive precisely when needed most. Eliminate single-wheel spin and maintain continuous power delivery for dominant corner exits.
• Lightweight & Robust: Achieve unparalleled agility with a significantly lighter design crafted from aerospace-grade 7075 Aluminum housings and durable hardened steel internals. Built for endurance, a robust 900 ft-lb (1220 Nm) torque capacity ensures unmatched reliability through every dynamic event.  Our most common architecture is ~3.7kg with advanced options able to reduce the weight to ~3.2kg.  These weights include the complete sealed diff, bearings to mount into your mounting structure, sprocket flange, and tripod housings.  No extra parts needed.
• Precision Power Transfer: Our proven Geared ATB/Torsen Limited Slip technology provides smooth, progressive torque biasing, maximizing traction out of corners with less maintenance than traditional clutch-type differentials.
• Plug-and-Play Integration: The Mk3 arrives as a complete, race-ready system, including high-quality bearings and tripod housings.  Simply mount it in your chassis and go - saving your team invaluable build time and resources.
• Rapid Pitlane Serviceability: Perform full rebuilds and crucial adjustments without needing to remove the differential from its bearing mounts or loosening the chain! This unique feature dramatically cuts down on time and effort during testing and development tuning.
