The Dana 44™ Front Crate Axle.

The Dana brand is the global leader in drivetrain components. Dana axles set the standard for other aftermarket axle manufacturers who call their axles “Dana 44s”, just like most of us call cotton swabs Q-tips. But make no mistake—if you’re not buying genuine Dana, you’re not getting the same quality and performance in your parts.
 

With Dana’s innovative Crate Axle program, we’re making it even easier for you to get the exact OE-quality axle you need, right out of the box. Get 100% genuine Dana 44™ product (including housing, gears, bearings, and axle shafts) quickly and easily.
 
 
 
 
 
 

Dana 44™: Better Than the Rest. Better Than Ever.

 
While it’s not easy to improve upon the best, Dana 44™ axles are now even better! Thicker wall tubing increases axle strength and raises the gross axle weight rating. Combine that with genuine Spicer™ chromoly axle shafts and gearing, plus Spicer® SPL® 1350 u-joints, and you'll have unparalleled strength and performance on any terrain. See the diagram below for additional features and benefits of the new-and-improved Dana 44™.
 
  1. Spicer® chromoly axle shafts for optimal strength and performance
  2. Thicker wall tubing for increased axle strength
  3. Genuine Spicer® gearing
  4. Open and selectable electric locking differential options
  5. Spicer SPL® 1350 u-joints with triple lip seals and full-circle snap rings for ultimate protection and retention

Note: These ratings are general guidelines. Actual load rating and torque limit will vary by application and duty cycle.

GAWR is Gross Axle Weight Rating. Maximum distributed weight an axle can support. GVW is Gross Vehicle Weight Rating. Maximum allowable weight of vehicle when fully loaded. GCW is Gross Combined (vehicle and trailer) Weight Rating. Maximum combined mass of vehicle and trailer when both are fully loaded. Torque limit @ input (ft.-lbs.) is the maximum recommended driveline torque input into the axle flange/yoke at pinion.
