Branik Motorsports Forged 4340 Chromoly Outer Stub Shaft - Dana 60 Chevy/Dodge - 35 Spline
Upgrade your Dana 60 front axle with Branik Motorsports' premium forged 4340 chromoly outer stub shafts—engineered to deliver up to 30% more strength than stock axles. Built for extreme performance applications with large tires and high horsepower, these heavy-duty outer stubs are the perfect upgrade for Chevy and Dodge trucks running Dana 60 front axles from 1978-1991.
Forged 4340 Chromoly - Premium Aircraft-Grade Material
What sets Branik outer stub shafts apart from stock replacements and budget alternatives is the use of premium aircraft-quality 4340 chromoly steel. This high-tensile-strength alloy provides:
- Superior Strength: Up to 30% stronger than factory steel axles
- Exceptional Toughness: Resists breaking under extreme shock loads
- Impact Resistance: Handles the abuse of rock crawling, mud bogging, and high-horsepower applications
- Fatigue Resistance: Longer service life under repeated stress cycles
4340 chromoly is the material of choice for professional racing, heavy-duty off-road use, and high-performance builds.
Double Heat-Treated for Maximum Durability
Branik goes beyond standard heat treatment with a proprietary double heat-treat process:
First Heat Treatment:
- Through-hardened shaft and yoke ears
- Develops core strength throughout the entire shaft
Second Heat Treatment (Induction Hardening):
- Surface hardening over the entire shaft area
- Creates a wear-resistant outer layer
- Protects against scoring, galling, and surface wear
This dual heat-treatment process produces outer stub shafts that are significantly tougher and more durable than single heat-treated or non-heat-treated alternatives.
Fully Machined Shaft and Yoke - Precision Engineering
Every Branik outer stub shaft is fully CNC-machined to exacting tolerances:
- Precision Splines: 35-spline profile machined for perfect fit in Dana 60 outer hubs
- Reinforced Yoke Ears: Thicker than stock for increased strength
- Machined U-Joint Bores: Accept full-circle snap rings for secure retention
- Smooth Surface Finish: Precision machining ensures proper bearing fit and seal contact
1480 Series U-Joint Compatibility
The yoke ears are machined to accept standard 1480 series u-joints with 1.375-inch (1-3/8") diameter bearing caps.
