A significant upgrade from OEM Dana 30 axle shafts. Engineered for maximum strength and consistent performance, these constant velocity axles eliminate the oscillation and "crow hop" characteristic of traditional U-joint designs — maintaining complete structural integrity across steering angles up to 45 degrees, including full lock positions.
Key Features
Six fully-engaged contact points for complete structural integrity at all steering angles
Dual-heat treated 4340 chromoly steel with profiled geometry for optimized load distribution
Fully assembled and ready for installation
Advanced Engineering
Double Arc Ball Cage: Dual-arc ball channel design distributes load evenly across two primary stress points, preventing ball migration during acceleration and deceleration for smooth, consistent power delivery
TPE Thermoplastic Elastomer Boots: Manufactured using German Osberg blow-molding technology with DuPont TPEE rated from -60°C to +160°C — 3x the service life of conventional rubber boots, superior protection against dust, moisture, and contaminants
OETIKER Stainless Steel Clamps: OEM-approved supplier precision clamps with deburred and edge-rounded contact surfaces to minimize boot damage and ensure sustained seal performance
