Speedmaster Quick Change 31 Spline TorqueWorm Helical Gear Torsen Limited Slip Differential PCE204.1075

The Speedmaster PCE204.1075 is a quick change 31 spline limited slip differential featuring TorqueWorm helical gear technology and Torsen design. This component is engineered for high-performance drivetrain applications where controlled power distribution and reduced wheel slip are critical. The quick change design enables rapid differential swaps without removing the entire axle assembly, making it ideal for competition, street performance, and specialty automotive builds that demand precision handling and traction management.

The 31 spline shaft interface provides secure, repeatable engagement for demanding driving conditions. The helical gear configuration with Torsen technology delivers progressive locking characteristics, improving cornering performance while maintaining smooth power delivery during acceleration. This differential is compatible with quick change-equipped vehicles and is a direct replacement for OEM units designed to accept this spline count and mounting standard. Suitable for drag racing, road course, and high-horsepower street applications where differential performance directly impacts vehicle control and acceleration consistency.

Key Features & Benefits

• 31 Spline Quick Change: Rapid differential installation and removal without full axle disassembly, enabling fast component swaps in competition and performance environments.
