ORIGINAL: 06Saleen3V J, the ft/lbs of torque is the torque for the bolts on the U-joints (correlating to their strength) not how much ft/lbs of torque the actual driveshaft can handle The above is not an accurate statement in regards to theasked question which was for torque ratingof a 1330 series u-joint, those ratingsare not for the "bolts on the u-joint".....what bolts? there are no bolts retaining the u-joints to the shaft, the are held in byretaining rings. The rating is actually the "continuous torque rating" for the u-joint,and on a1330 series u-joint that would be 130 lbs/ft and for a 1350 series it would be 210 lbs/ft. Now what that means is that Danau-joints on a "gas or diesel engine" are rated for steady state torque at the above mentioned ratings which in return assures a long life cycle of the u-joint. Those u-joints are also rated for "short duration torque" of 890 lbs/ft for the 1330 series and 1240 lbs/ft for the 1350 series joint. So to answer the question properly, the 1330 u-joints will be fine for most applications, but it wouldn't be a bad idea to upgrade to the 1350 joints, especially since the other side of the shaft (the one opposite the internal slip spline) should already have a 1350 series in it. The 1330 will have a shorter life cycle than the 1350's if you consistently run above the "continuous torque rating" but most should be fine, just run a driveshaft loop and if you drive hard frequently, inspect your driveshaft to insure that the u-joints and fasteners that hold either end to the car are intact with no obvious imperfections.
