      Description

      Reliable Torque and Towing. Upgrade your RAM 3500’s drivetrain with the USA Standard Gear 11.50-Inch Rear Axle Ring and Pinion Gear Kit, featuring a precise 3.73 gear ratio and a durable 11.50-inch ring gear. Whether you’re towing heavy loads, hitting steep grades, or simply restoring differential performance, this kit is engineered to deliver consistent power, smooth operation, and long-lasting durability under pressure.

      The Perfect Balance of Power and Efficiency. The 3.73 gear ratio of this USA Standard Gear 11.50-Inch Rear Axle Ring and Pinion Gear Kit strikes the sweet spot between towing strength and highway fuel economy. It delivers better low-end torque than higher ratios like 3.21, without sacrificing too much efficiency on longer drives. If your RAM sees regular towing duty or off-road time, 3.73 is the reliable go-to.

      Built for Strength. The USA Standard Gear 11.50-Inch Rear Axle Ring and Pinion Gear Kit is made from premium-grade forged steel, ensuring maximum resistance to heat, wear, and high-load conditions. The machining tolerances are tight, the fitment is precise, and the finish resists corrosion and premature gear wear.

      Installation. Putting this USA Standard Gear 11.50-Inch Rear Axle Ring and Pinion Gear Kit; 3.73 Gear Ratio on your RAM 3500 takes 4 hours to install.

      Warranty. There is a 1-year warranty on this product.
