Eaton Detroit Truetrac Differential 30 Spline 1.29in Axle Shaft Diameter 3.54-5.29 Ratio

Eaton is well-known for their robust drivetrain components, and the Detroit Truetrac differential is a prime example of their expertise. If you're looking to improve traction and handling in a wide range of vehicles, this helical-gear limited-slip differential is a solid choice. It's designed to automatically send power to the wheel with more grip, enhancing acceleration and control whether you're on the street or tackling rougher terrain. This unit fits a variety of trucks and SUVs, including models like the Toyota 4Runner, Tacoma, and Tundra.

What sets the Truetrac apart is its smooth, quiet operation. Unlike some other limited-slip designs, it uses helical gears that engage automatically without the need for special friction modifiers or lubricants, making maintenance straightforward. This means you get consistent, reliable traction in both forward and reverse, without the chatter or harshness sometimes associated with clutch-based differentials. The torque bias ratios are optimized to deliver maximum acceleration and handling, giving you more confidence behind the wheel.

This particular Detroit Truetrac is built for 30-spline axles with a 1.29-inch shaft diameter and is compatible with gear ratios ranging from 3.54 to 5.29. It's a durable, maintenance-free unit that works seamlessly in forward and reverse, making it an ideal traction solution for many different types of vehicles. When installing, always refer to the manufacturer's instructions for proper setup and any specific requirements for your vehicle's drivetrain.
