YUKON DANA 44 Super Joints

297x Super Joints, grease and a grease gun The Super Joint is 90% stronger than OEM joints. How's that, you ask? Well, first off, the trunion size is increased, offering a 72% strength increase. The Super Joint eliminates needle bearings which crush and disintegrate during extreme use. By foregoing the needle bearings the Super Joint eliminates needle-bearing lock up, which typically destroys axles and U-joints by rotating the snap rings and caps out of place. The strength doesn't stop there. The Super Joint utilizes 4340 Chromemoly forged material, which offers an additional 25% strength increase (based on OEM joints). Also there is an ionically bonded coating, as well. This specialized coating eliminates the need for bearings or brushings, and for periodic rebuilding, as compared to other aftermarket U-joints. The high temp copper and graphite EP compound (the finely divided soft metals and solid lubricant) make sure to prevent metal to metal contact under 200,000 psi loads, and will not break down in temps up to 2000 o Farenheit. This compound also creates a hardened copper bushing between the cap and trunion substrates. Quality like this is hard to find. And the full circle snap rings prevent the caps from working out of the axle cups. Super Joints are made with strength, endurance and quality in mind. This kit includes two 297x Super Joints, grease and a grease gun
