Speedmaster PCE204.1031 GM 8.875" 12 Bolt 30 Spline LSD Limited Slip Differential

The Speedmaster PCE204.1031 is a GM 8.875" 12 bolt limited slip differential (LSD) engineered for truck axle applications. This differential features a 30 spline design and delivers improved traction through its limited slip mechanism, which allows controlled power distribution between wheels during acceleration, cornering, and challenging driving conditions. The 12 bolt mounting configuration is compatible with GM truck platforms utilizing the 8.875" axle housing standard.

Ideal for truck owners seeking enhanced handling and traction performance, this differential replaces standard open differentials with a more responsive drivetrain feel. The limited slip design reduces wheel spin and delivers more consistent power delivery across various terrain and weather conditions. Built to OEM specifications, the PCE204.1031 integrates seamlessly into existing GM truck axle assemblies, making it suitable for both street and light off-road applications where improved traction characteristics are valued.
