The GM/Dodge 11.5 Ring & Pinion 3.73 Ratio by MOTIVE GEAR is a vital drivetrain upgrade for truck and SUV enthusiasts aiming to enhance highway cruising efficiency and towing performance. This ring and pinion set is designed to replace worn OEM gearing, providing a 3.73 ratio that balances fuel economy and torque multiplication for various driving conditions.
The 11.5-inch ring gear diameter is crucial for fitting into GM and Dodge heavy-duty differentials. The 3.73 gear ratio indicates that for every 3.73 rotations of the driveshaft, the wheels rotate once, enhancing throttle response and torque delivery. MOTIVE GEAR manufactures these components to OEM-equivalent tolerances using premium steel, which contributes to smooth operation and extended service life.
This ring and pinion set is compatible with full-size GM trucks (Silverado, Sierra) and Dodge Power Wagons equipped with 11.5-inch differentials. It is ideal for owners looking to upgrade aging or damaged components. Proper installation requires a differential carrier bearing preload setup and careful gear mesh adjustment, best performed by experienced technicians with specialized tools.
