1.76 Based Gear Set Reverse Ring Gear - 4140 HT - 12 DP, 1.82 Straight Cut, SG4

ATI Racing offers high-quality reverse ring gears in both steel and lightweight aluminum versions. Each aluminum ring gear is fully computer-machined from space-age aluminum and are hard-coated to 60 RC for long life. Weighing a mere 15 ounces, they are over 60% lighter than the lightest steel unit. Steel options, including OEM-style helical and straight-cut designs, deliver proven durability under torque. Ideal for performance and factory rebuilds, ATI’s reverse ring gears maintain precise gear alignment and are engineered to reduce rotational mass, enhancing transmission efficiency and responsiveness. Note that aluminum variants are not recommended for use with transbrakes.
