Generally, aftermarket shafts have to be purchased Pattern in most cases differed from the car, and due to the bearing sizeĭifferences, 28-spline car axle shafts are much more abundant than theģ1-spline car shafts. When it comes down to actual shafts as well, since the truck lug
The few cars and early Broncos (and some early trucks) which received TheĪctual car posi units, which were primarily 28-spline carriers, can be More plentiful starting in the early 1970's, many of the units found todayĪt car swap meets and shows are the units pulled from trucks with theģ1-spline carriers and "Traction Loc" style posi unit. (often referred to as a "POSI") came to be a popular option and Since the "Limited slip" or Locking rear end Wheel drives) right up until about 1982, these housings are by far the Many half ton trucks continued to utilize the 9-inch (both 2 wheel & 4 Gross Vehicle Weight ( GVW ) wouldĭetermine which axle housing many cars and trucks received.

Most of the later trucksĪlso received the larger axle bearings housings. Trucks varied more, early half ton trucks got the 28-spline axles andĬarriers, while sometime in the early 70's the switch was made to mostlyģ1-spline axles and carriers for most trucks. Of course most desirable is the N case, first used on the 427 GalaxiesĪround 64-65 I believe.They are most often found behind the later 428CJĪnd 429CJ cars.From what I have seen don't expect to find them in 390 orĢ89 Hipo cars.The N cases went with 31 spline centers and are for ruggedĭuty.And believe it or not, they were also used in some FE equipped Ford Some of the heavier cars like the Galaxies also received the Exceptions to this were the ultra Hi performance Boss 302’s,īoss 429’s, 427’s, 428 CJ/SCJ and the 429 cars which received theģ1-spline carriers and axle shafts.
