GRIT GEARS 4340 Chromoly Front CV Axles for Jeep JL Rubicon Wide Track Axle Housing (USA)

GRIT GEARS 4340 Chromoly Front CV Axles for Jeep JL non-Rubicon represent a significant upgrade from OEM Wide Track Dana 44 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.
• The six fully-engaged contact points maintain complete structural integrity across steering angles up to 45 degrees, including full lock positions.
• Double Arc Ball Cage The dual-arc ball channel design distributes load evenly across two primary stress points, preventing ball migration during acceleration and deceleration cycles. This geometry ensures smooth, consistent power delivery while extending overall component longevity.
• TPE Thermoplastic Elastomer Boots Manufactured using German Osberg blow-molding technology, these boots utilize DuPont polyester thermoplastic elastomer (TPEE) rated for temperatures from -60°C to +160°C. The advanced material composition delivers three times the service life of conventional rubber boots, providing superior protection against dust, moisture, and environmental contaminants.
• OETIKER Stainless Steel Clamps Premium stainless steel clamps from OETIKER—the OEM-approved supplier—secure the boot assembly with precision engineering. Deburring and edge-rounding on all contact surfaces minimize boot damage during installation and operation, ensuring sustained seal performance.
  Material & Construction Dual-heat treated 4340 chromoly steel with profiled geometry optimizes load distribution.
• Fully assembled and ready for installation.
