Yukon Gear 38″ Long 4340 Chrome-Moly Inner Axle for 30 Spline Dana 60

Description

Product Overview

The Yukon Gear 38″ long 4340 Chrome-Moly inner axle is a premium replacement component designed specifically for the 30‑spline Dana 60 differential. Constructed from high‑strength 4340 alloy steel, the axle undergoes a rigorous heat‑treatment process that yields a hardened, wear‑resistant surface while maintaining a tough core for shock absorption. At 22 lb and measuring 38 in in length, the shaft offers a perfect balance between mass and rigidity, reducing rotational inertia and improving drivetrain response. The chrome‑moly coating provides corrosion resistance in harsh environments, extending service life for off‑road trucks, heavy‑duty pickups, and commercial vehicles. Precise machining tolerances ensure a seamless fit with existing carrier housings, splines, and universal joints, eliminating the need for additional modifications. This axle meets or exceeds OEM specifications, making it a reliable, drop‑in solution for professionals seeking durability without compromise.

Usage

Designed for a wide range of applications, this inner axle excels in both on‑road and off‑road scenarios. It is ideal for trucks that regularly haul heavy loads, tow trailers, or navigate rugged terrain where torque spikes and sudden impacts are common. The 30‑spline design aligns with standard Dana 60 carrier housings, allowing installation in lift‑kits, performance differentials, and aftermarket gear sets. Whether you are upgrading a fleet of work trucks, preparing a custom build for off‑road competition, or simply replacing a worn‑out OEM part, the axle delivers consistent power transfer and reduces the risk of spline wear. Its robust construction also makes it suitable for agricultural equipment, construction machinery, and any vehicle that demands reliable torque distribution under demanding conditions.

FAQ

What vehicles are compatible with this inner axle?

The axle is compatible with any vehicle that uses a 30‑spline Dana 60 differential, including many heavy‑duty trucks, commercial pickups, and off‑road builds. It fits standard carrier housings without the need for additional machining.

Do I need any special tools to install the axle?

Installation requires standard drivetrain tools such as a torque wrench, bearing puller, and spline lock ring installer. No proprietary equipment is needed, and detailed installation instructions are provided with the product.

How does the chrome‑moly coating improve performance?

The coating creates a hard, wear‑resistant surface that protects the steel from rust, moisture, and abrasive particles. This reduces maintenance intervals and helps maintain consistent spline engagement over the life of the axle.
