Having issues wearing out CV Axles? DmaxStore has the solution, this extended travel CV axle assembly was designed for the rigorous abuse that Duramax owners put their trucks through with the added stresses caused by modifications to the vehicle the stress on the stock components can often lead to failures. This axle allows for a full 47 degrees of articulation versus the 23 degrees that the factory axle allows, making it perfect for leveled and lifted applications. The thermoplastic elastomer boots offer better life than many of the other boots on standard CV axles. The advantages of these thermoplastic elastomer boots include: ideal flex fatigue characteristics, exceptional tear resistance, protection against water and a wide temperature capability. The upgraded cages, races and bearings allow for smooth operation even at the highest degree of articulation unlike some competitors, this is achieved by the 8 bearing joint versus the factory 3 bearing joint that can limit the articulation and smooth operation of the CV axle. This axle also carries a lifetime warranty against defect and workmanship so you can rest assured your parts hold up ot the test of time.
