Description

The Dana 35 Rear Axle Ring and Pinion Gear Kit with a 3.45 gear ratio is designed to optimize fuel economy while maintaining reliable performance for mild off-road use. Made from premium heat-treated steel, the gears are precision-machined to deliver smooth, quiet operation and superior wear resistance. The 3.45 ratio provides balanced performance for both daily driving and weekend trail runs, and it's fully compatible with both OEM and aftermarket differential components. Installation is hard and requires advanced mechanical skills, specialized tools, and precise setup for proper backlash and tooth contact. Professional installation is highly recommended for best results and long-term reliability. The product includes a one-year limited warranty, covering defects in materials and workmanship under normal use.
