The 3.55 12 Bolt GM Pass ring and pinion gear set from Richmond is designed for automotive builders and enthusiasts looking to upgrade their differential systems. This complete gear package is tailored for GM's durable 12-bolt passenger axle, commonly used in street machines and daily drivers that require enhanced performance without compromising reliability.
Manufactured to OEM tolerances, this gear set is crafted from high-quality steel forgings, ensuring a smooth mesh and minimal backlash when properly installed. The 3.55 gear ratio provides a balance between highway efficiency and low-end torque, making it a popular choice among modifiers seeking noticeable performance improvements. It is important to note that actual performance gains can vary based on vehicle setup and usage.
This gear set is compatible with Chevrolet, GMC, and Pontiac vehicles equipped with the 12-bolt rear axle from the 1960s through the mid-1980s. While installation may be straightforward for experienced mechanics, it is recommended to seek professional differential service to ensure optimal performance and reliability. The gear set pairs well with limited-slip differentials or locking units to enhance traction during acceleration.
