Overview

The TorqueWorm is a torque biasing 6 pinion gear type limited-slip unit. This is a preloaded unit allowing for a faster-reacting unit. The use of 6 pinion gears means the stress on gears is spread over a greater surface area, reducing the load on all internal components. The internal components are made from EN36 Material as used in racing. The outer cases made from 8620 Chrome-Nickel-Moly steel and the case hardened for long life and improved strength.

Description

The GM 8.875" (often rounded to 8.9") 12 Bolt axle is available in passenger car (GM 12P) and truck (GM 12T) rear axle configurations and features an 8.875" ring gear and 30 spline semi floating axle shafts. While both versions of the axle have similar specifications on paper, they do have unique differential carrier housings and most parts, including ring and pinion gears are not interchangeable. Because both axles are commonly referred to as GM 12 Bolt axles, it is important to know which version you have before ordering your parts.

The easiest way to tell them apart is that the passenger car version has a perfectly round differential cover while the truck version has an irregular shape.
