The TEN FACTORY MG20126B is a 19-spline front axle shaft built for the Ford Dana 44 found under 1978-79 fullsize Ford SUVs. It replaces a worn or twisted original equipment shaft with a forged 4340 chromoly piece that holds up to moderate off-road duty without going overboard on cost. At 9.72 inches long and roughly 4.2 lbs, it drops into the stock location and works with the factory hub and joint setup. This is a straightforward upgrade for anyone running OE-size tires who wants a stronger shaft than the worn unit currently turning the wheels.
TEN FACTORY forges this shaft from 4340 chromoly steel, then heat-treats and CNC machines it for consistent spline fitment and strength under load. The 19-spline configuration matches the Ford Dana 44 it's cut for, and the black oxide coating adds corrosion resistance over bare steel. It runs the 5-760X U-joint, so you can pair it with a matching joint from our universal joint selection when you rebuild the assembly. The shaft is engineered for original equipment tire sizes and moderate off-road use rather than competition rock crawling, which keeps the strength-to-cost balance sensible for daily drivers and weekend trucks. TEN FACTORY backs it with a 10-year, 100,000-mile warranty per manufacturer specifications.
Reach for this shaft when you're servicing a 1978-79 Ford Dana 44 front end and the original axle is worn, cracked, or already broken. It's a good time to inspect bearings, seals, and the joint while you're in there, and to grab a fresh Dana 44 shim kit if you're resetting carrier preload. Buyers chasing a clean rebuild often pull related hardware from our broader drivetrain parts lineup in one order. If you're running OE tires and moderate trail use, this TEN FACTORY shaft gives you a stronger replacement without paying for capability you won't use.
