High Lifter CV Axles are built tough to handle any terrain. They are made with Chromoly Steel. They have a 20% increase in axle diameter and a 15% increase in CV Joint size. The axles are double plunging with a high angle up to 40 degrees. The internal CV Joint components are precision machined and have induction heat treated bearing, CV cage and races to reduce friction and increase CV joint strength and durability. High Lifter uses Molybdenum Grease and durable TPEE CV Joint Boots resistant to tearing and abrasion. TPEE provides outstanding strength, stiffness and overall durability.
