POWERTRAX Grip LS Differential LS201030 for GM 10-Bolt 8.5-Inch, 30-Spline, 2.73-and-Up Ratio

Upgrade your GM 10-bolt differential with the POWERTRAX Grip LS Differential, part number LS201030. Designed for 8.5-inch GM 10-bolt rear ends with 30-spline axles and 2.73-and-up gear ratios, this limited-slip differential helps improve traction by directing power to the wheel with available grip. It is a practical choice for street-driven vehicles, performance builds, and applications that need more consistent rear-wheel traction without the complexity of an air-actuated locking system.
The POWERTRAX Grip LS features a durable steel construction designed for dependable service under demanding driving conditions. Its limited-slip operation helps reduce one-wheel spin while maintaining smooth, predictable behavior during normal driving. By improving power transfer across the axle, the differential can support better acceleration and control on varying road surfaces while preserving everyday drivability.
Designed as a direct-fit drivetrain component for compatible GM applications, this differential is intended for installation by a qualified technician familiar with axle setup and differential service. Confirm vehicle compatibility, axle housing specifications, spline count, and gear ratio before installation. The POWERTRAX LS201030 is supplied as an individual differential assembly and does not include unrelated installation components unless specifically stated by the manufacturer. It is not air-actuated and does not require an onboard air system.
