Jana 54

JANA 54™ kit Installs Dana 50 gears into Dana 44 High Pinion housings, making them 44% stronger. As seen in Crawl Magazine, This Dana 50/44 hybrid kit comes complete with all adapter bearings, standard bearings, seals, shims, spacers & instructions, to install a Dana 50 gear set with a Dana 44 carrier 3.73 & down (or Posi) into the D44 HP diff housing. Gear ratios available: 4.11, 4.30, 4.56, 4.88, 5.13, & 5.38. Jana 3/8" thick cover girdles also available.

If you can install ring & pinions & use a grinder you can install this strength improving kit. If you are running alloy axles then you need this kit as the Ring & Pinion is now the weak link in your drive-train. This kit allows you to upgrade to 31, 32, 33 or 35 spline axles without having the limited strength of the 44 ring and pinion, yet not lose any ground clearance.
