Installing Superior Axle & Gear's Super 44 Kit
PhotosView Photo Gallery
Makers of the popular Super 35 Kit designed to add strength to Jeep TJs equipped with Dana 35 rear axles, Superior Axle & Gear is now offering its Super 44 kit for Jeep TJs with the Dana 44 factory option. Using Superior's Evolution-series axleshafts, the kit affords the ability to upgrade the stock 30-spline axleshafts to 33-spline 'shafts for a significant increase in strength. This is an excellent means of gaining rear axle muscle without the expense or hassle of a custom axle swap.
Superior designed, engineered, and manufactured the Super 44 Kit in-house, basing improvements upon customer feedback. The Evolution-series axles are constructed from an induction-hardened alloy and offer cold-formed rolled splines, which are said to be as much as 40 percent stronger than the usual cut-spline process. The axleshafts feature a DuraCoat finish and are predrilled for dual bolt patterns for those eager to upgrade to a larger 5 on 5-1/2 lug pattern. Each kit offers everything required for a simple bolt-in installation, and includes left and right axleshafts, a newly designed 33-spline Detroit Locker, Timken tapered roller bearings, axle bearings and seals, and Grade 8 thread-in lug studs. Superior also indicated that a 33-spline Dana 44 ARB Air Locker option should be available later this year.
Recommended for Jeep TJ vehicles equipped with 35-inch-or-larger tires, or those seeking a heavier-duty axle option without the added weight and expense of a Dana 60, the Super 44 Kit from Superior Axle & Gear is a great alternative to achieving the bulletproof axle assembly your Jeep TJ deserves. We followed along with the crew at Currie Enterprises as it carried out a Super 44 installation on a vehicle that had previously fallen victim to a broken 30-spline axleshaft.
