Review MOTIVE GEAR Differential Carrier Kit
The Motive Gear GM12BI Differential Carrier Kit is an essential upgrade for gear enthusiasts and professional racers seeking high-performance and durability in their differential setup. This kit is specifically designed for GM 12-bolt rear ends, making it an excellent choice for classic cars, hot rods, and racing applications.
The heart of this kit is a robust, forged 300M case carrier made from billet steel. The forging process ensures superior strength and rigidity, reducing the likelihood of failure even under extreme loads. The carrier is also laughingly referred to as a "no-hanger" design, as it eliminates the need for upper and lower control arms, making installation easier and saving weight.
The kit includes a set of Motive's famous, precision- machined, and heat-treated replaceable pinion bearings. These bearings are renowned for their exceptional robustness and ability to handle significant torque loads. Additionally, the kit comes with an 8.8-inch, chicklet bronze differential housing. This housing is known for its durability and heat resilience, ensuring that the differential remains cool and functions effectively even under heavy racing conditions.
The Motive Gear GM12BI Differential Carrier Kit also includes marginally misaligned pinion yokes, an essential feature for eliminating any potential vibrations or noise in the driveline. Furthermore, this kit provides the flexibility to use a variety of ring and pinion sets, allowing you to customize your setup to suit your specific needs.
To make installation even more accessible, the kit includes a set of adapter plates compatible with a wide range of input shafts, including standard, offset, and flanged examples. The comprehensive installation instructions included in the kit make the installation process straightforward, even for those with less experience.
In summary, the Motive Gear GM12BI Differential Carrier Kit is an exceptional upgrade for anyone seeking a high-performance and durable differential setup for their GM 12-bolt rear end. With its robust forged carrier, precision-machined bearings, and flexible ring and pinion options, this kit provides the perfect blend of strength, performance, and adaptability.
