Reviews: Dana Spicer Dana 44 Ultimate JK Front Axle Assembly 4.88 Ratio - 10010521

Had this installed the other day on my 2011 Wrangler sport 2dr with 82k miles on it. I Was getting 11.2 mpg avg running a 4 in lift with 35x12.5x17 Cooper evo MT. The plan at first was to re gear the front and rear 30 and 44 from 3.73 and go with 4.88 ring and pinion and install Detroit trutrac lockers. After many days of researching and pros and cons of everything out there on the market I decided after one guy’s posts on a Jeep forum he said why not while you’re rebuilding that Dana 30 with the miles you have on it you’re gonna be in those axles anyway you might as well replace the seals and ujoints ball joints and everything else so I came across the Dana ultimate 44 it comes with whatever gear you want comes with an elocker chromoly axle shafts oversized ball joints 1350 ujoints and extra support gussets stiff as a board this thing does not flex at all compared to the 30 stock axle and for $450 more and $595 to install it worth every penny no more bump steer. Went ahead and rebuilt the rear with 4.88 G2 ring and pinion Yukon master install kit Yukon axle seals. I’ve gone from avg 11.2 mpg to 17.9 mpg worth every penny.

I feel this axle is the best upgrade I could have done for the money. Great value and amazing quality!

I was looking at upgrading my 2017 JKU Sport with a 3.5 inch lift and 35 inch tires to be able to fully utilize it again, and get my sixth gear back. After pricing everything out to build from the ground up I came to the conclusion that this was a steal. It comes ready to go, components are solid, true and reliable for a vehicle that is a daily driver and off-roads. Got my sixth gear back at some of my mpg. Only complaint is that you have to make sure you purchase the Dana splicer harness part # 10021771. I was not informed of this, so had to run it for two months with a useless front locker. The harness is plug and play, easy install on your own. Just wish I would have known it at time of install. Besides that this axle is a beast. Solid build and reliable while saving you money and time. I would recommend it.
