A limited-slip differential, applicable to General Motors’ G-body vehicles, enhances traction by distributing torque to both rear wheels. This contrasts with an open differential, which may send power only to the wheel with less grip, leading to wheelspin in slippery conditions. This particular component provides improved handling and acceleration, particularly in situations where traction is compromised.
The inclusion of a limited-slip differential, often referred to by a specific colloquial term, significantly improves performance characteristics. Historically, these differentials were desirable upgrades, offering benefits for drag racing, autocross, and even everyday driving in adverse weather. The enhanced grip translates to quicker launches, better cornering stability, and increased driver confidence.
